This series will include the leading works on International Law, the republica- tion of which has been undertaken principally on account of the difhculty of oro- curing the texts in convenient form for scientific study. The text of each author wi 1 be reproduced photographically, so as to lay the source before the reader without the mistakes which creep into a newly printed text. An Introduction will be prefixed to each work, giving the necessary biographical details concerning its author and stating the importance of the text and its place in International Law; tables of errata in the origmal will be added when necessary, and notes to clear up doubts and ambiguities or to correct mistakes in the text will be supplied. Each work will be accompanied by an English version made expressly for the series by a competent translator. Dr. James Brown Scott, member of the Institute of international Law, will supervise these publications as General Editor.

Quarto, 2 vols. Published 1906. Price $14 00 Vol. 1. The Catalogue, Lv-f256 (256a-256r) pages. Vol. 2. Notes to the Catalogue, viii-f 257-1086 pages. A catalogue of all the double stars visible in the northern hemisphere, discovered since the earliest records, with all the measures and other observations from Her- schel in the seventeenth century to the latter part of 1906. In volume 1 the stars are given in order of right ascension, in tabular form, in eleven columns giving respectively the general number, the name of the double star, a reference to one of the principal star catalogues in which the star is found, the right ascension, the dechnation, the measured position-angle, the measured distance, the magnitudes of the components, the date of the measures given, the observer and number of ob- servations, and lastly brief notes concerning colors, etc. The first portion of this volume contains some fifty pages of introductory matter, including ten indexes to the various observers, classes of stars, etc., enabling the user to find at once any special star, or class of stars, without a knowledge of the star places. Volume 2 f?^i^i"j complete references to all the observations of each of the 13,665 double stars. All published orbits of the binary systems and the proper- motions of the brighter stars are given. The history of each pair includes a selec- tion of the best measures showing motion, if any, and an examination of the mate- rial questions suggested by the measures. Some 600 diagrams, drawn to exact scale show the relative change in the systems having decided orbital and proper motions.' No. 168. BuRNHAM, S. W. Measures of Proper Motion Stars. Quarto, iv+Sll pages. Published 1913. Price $4.00. Micrometer measures made with the large telescope of the Yerkes Observatory from 1907 to 1912 of various stars having large, small, or uncertain proper-motions. These selected stars are of all magnitudes from the faintest in Argelander to prom- inent naked-eye stars, and include, as far as possible, all those which have been heretofore compared by direct measures with other and fainter stars in the field. Independent differential values of the proper-motions are thus obtained for com- parison with_ the results found from meridian observations. The latter values are frequently discordant and contradictoiy, and particularly so when the motions are small. The several values from the leading authorities on meridian-circle observa- tions, Auwers, Newcomb, Porter, Boss, etc., and from the various standard star catalogues, are collected and compared. The greater number of proper-motion stars observed here are taken from the General Catalogue of Double Stars. The others are selected from various sources and include stars of special interest, among others the Boss group of Taurus stars with a common movement in space, and small stars with supposed proper-motions taken from the Oxford and other astro- graphic catalogues. As a rule, each star is measured on three or more nights, and very faint comparison-stars selected which, it is safe to say, have no sensible motion which could affect the result obtained. No really faint star, not attached to and moving with a brighter star, has ever been shown to have any proper-motion which could be detected by any method of observation to this time. Of course it is to be presumed that the faintest and most distant stars have both proper-motion and parallax,^ and it is equally obvious that the one is as negligible as the other in all differential comparisons. A careful remeasurement of these small stars after a suitable interval of time will give the movement of the principal stars with a degree of accuracy not yet attained by other methods. 21 22 Astronomy No. 9.

Vol. 1, 381 pages ; vol. 2, 346 pages ; vol. 3, 577 pages ; vol. 4, 466 pages. The above volumes comprise the works of Dr. Hill in dynamical astronomy, mathematical physics, and mathematics complete up to 1907. The memoirs, 84 in number, are arranged chronologically, the date of the earliest being 1859. The last five memoirs appear here for the first time.

Catalogue of Stars within Two Degrees of the North Pole, Deduced from Photographic Measures. Octavo, 85 pages. Published 1905. Price $0.50. This is an extension of the Star Catalogue presented in Publication No. 1 of the Vassar College Observatory, which gave a catalogue of stars within one degree of the North Pole, whereas the present publication extends the catalogue to two degrees from the North Pole. Both catalogues are based upon photographs taken by Professor Donner, of Helsingfors, Finland, a series of twelve negatives being under consideration, which together include all the stars of less than two degrees polar distance. The present paper treats first of the measurement and reduction of 89-degree plates, with a preliminary catalogue of the stars found thereon ; second, of the inter-adjustment of the several plates and their com.bination with the former catalogue; and third, of the form.ation of the final catalogue of all the stars found on twelve plates. No. 10. Newcomb, Simon. Contributions to Stellar Statistics. On the Position of the Galactic and Other Principal Planes Toward Which the Stars Tend to Crowd. Quarto, 34 pages. Published 1904. Price $0.25. A principal inquiry in the above paper is to determine the position both of the galaxy itself and of the planes toward which the stars appear to crowd, irrespective of the existence of the galaxy. Some previous inquiries might appear to show that the tendency to crowd toward the galaxy is well marked even in the case of stars visible to the naked eye, but the present investigation shows that this tendency IS less marked when the galactic stars are considered as forming a collection separate from the others. No. 72. Newcomb, Simon, assisted by Frank E. Ross. Investigation of Inequali- ties in the Motion of the Moon Produced by the Action of the Planets. Quarto, viii+160 pages. Published 1907. Price $1.00. The principal object of the above work was the hope of explaining by gravi- tational theory the observed variations in the mean longitude of the moon, shown by miore than two centuries of observations to exist, but not yet satisfactorily ac- counted for. The work naturally divides itself into four parts. One of these treats of the theory of the subject, including under this head not only the general equations, but the numerical details on which all the computations are based. In this part the fundamental quantities are reduced to products of two factors, one of which depends upon the coordinates of the planet; the other upon the geo- centric coordinates of the moon. The first factors, termed planetary, are numeri- cally developed in Part II. This development falls into two parts, one treating the direct action of the planet, the other the indirect action through the sun. In Part III is found the numerical development of the factors depending upon the moon alone, and of the partial derivatives as to the lunar elements. In Part IV are presented the combinations of these two factors and the final results of the work. No. 33. Parkhurst, J. A. Researches in Stellar Photometry. Quarto, 192 pages, 13 plates, 39 text figures. Published 1906. Price $2.00. The equalizing-wedge photometer is investigated and applied to stellar pho- tometry in measuring the comparison stars, from 6th to 16th magnitude, for :welve variable stars, using telescopes of 6, 12, and 40 inches aperture at the Yerkes Observatory. The fields, including the stars measured, are shown by half- tone charts from photographs taken with the 2-foot reflector. Light-curves of the Astronomy 23 variable stars are given from observations made between 1892 and 1905, by Arge- lander's method and with the photometer. The unique feature of the work consists in the application of photometric methods to faint stars near the limit of the Yerkes 40-inch refractor. No. 138. Adams, Walter S., assisted by Jennie B. Lasby. An Investigation of the Rotation Period of the Sun by Spectroscopic Methods. Quarto, III+132 pages, 2 plates, 5 text figures. Published 1911. Price $3.00. The results of a determination of the rotation period of the sun from the dis- placements of the spectrum lines. The material employed consists of tv/o series of photographs obtained at the Mount Wilson Solar Observatory during the years 1906-7 and 1908 with fixed spectrographs of high dispersive power. The methods of observation and reduction are discussed in full, and a comparison is made with the results of other observers and with the values of the rotation period as derived from studies of sun-spots, faculss, and flocculi.

A series of monochromatic photographs of the sun, made with the spectrohelio- graph of the Kenwood Observatory, in the years 1892-94, provided the material for this investigation. By means of a special measuring instrument the daily motions in longitude of the calcium flocculi in different latitudes were determined. It was found that the law of rotation for these flocculi is almost identical with that for sun-spots. The paper describes the Kenwood spectroheliograph and the globe- measuring instrument, as well as the methods of measurement and the reduction employed. No. 235. Hale, George E. Ten Years' Work of a Mountain Observatory: A Brief Account of the Mount Wilson Solar Observatory. 12mo, 99 pages, 65 text figures. Published 1915. Price, in paper cover, SO cents; in cloth, 75 cents. This little book has been written to meet a demand for information regarding the purpose and work of the Mount Wilson Solar Observatory. As it is intended for the general reader, untechnical language has been used and numerous illustrations have been provided. The purpose of the Observatory is to throw as much light as possible on the evolution of stars and stellar systems. Its researches naturally fall into three chief divisions, comprising: (1) Solar observations, for the purpose of adding to our knowledge of the only star open to minute analysis. (2) Stellar and nebular observations, bearing directly on the structure of the universe and the physical nature of stars and nebulse. (3) Laboratory investigations, for the imitation and interpretation of astro- nomical phenomena. The book describes typical methods of work, involving the invention, design, and construction of new telescopes and other instruments, their erection on Mount Wilson in Southern California, their use in photographing celestial phenomena, and the study and interpretation of the photographs in the offices and laboratories in Pasadena.

Published 1915. Price $3.50. This volume contains the results of a comprehensive and thorough discussion as to the positions for 1900, proper-motions, and other useful particulars in relation to all stars in both hemispheres that are visible to the naked eye. About 2,000 stars fainter than the sixth magnitude are also included, because they are among the stars which have been most precisely and frequently observed in the past. The primary object of this work was to employ substantially all useful evidence of 24 Astronomy observation in determination of proper-motions with a high degree of precision, especially in the systematic sense. Results of researches leading up to the present work have been published in Volume XXVIII of the Astronomical Journal. Therein are described the steps by which the results of the various original catalogues of observed star-positions are made systematically consistent — one with another, and with a resulting normal system. These and subsequent labors in preparation of the present work have led to various useful results, additional to those concerning the main issue — computation of systematically accurate proper-motions. Thus, the present work contains very carefully computed positions of all the stars suitable to be classed as standard stars. The systematic errors of observation due to magni- tude-equations of the respective observers have been eliminated from the right- ascensions of the catalogue with substantial success. In the catalogue is incor- porated a Normal Uranometry prepared by Dr. S. C. Chandler. This is founded upon all the most important measurements and estimates of brightness, rendered homogeneous by the application of systematic corrections for color and position in the sky. Three appendices contain respectively : Appendix I. Ephemerides of Polar Stars. Appendix II. Notes to the Catalogue, Periodic Proper-Motion, etc Appendix III. Systematic Corrections and Weights.

The observations of the first catalogue, which are strictly dififerentiai, were designed to meet the need of star positions in a region of the sky difficult of access to the principal European observatories. The second catalogue supple- ments the observations taken at Nikolaief. A third part of the publication contains the standard star positions observed in determining the system upon which the zone observations of the first catalogue are based and a number of miscellaneous star positions. Other miscellaneous stars form the fourth part. An appendix contains a list of the proper-motions amounting to more than 10 seconds of arc per century. No. 119. Perrine, Charles D. Determination of the Solar Parallax from Photo- graphs of Eros made with the Crossley Reflector of the Lick Observa- tory. Quarto, ¥+98 pages, 1 plate, 2 text figures. Published 1911. Price $2.50. This publication gives a detailed account of observations and computations made in deriving the solar parallax from photographs of the minor planet Eros taken by means of the Crossley reflecting telescope of the Lick Observatory during the interval October 1900 to January 1901. The value of the parallax deduced is 8.8067" ±0.0025". No. 147. Russell, Henry Norris. Determinations of Stellar Parallax, based upon Photographs taken at the Cambridge Observatory by Arthur R. Hinks and the writer; with Magnitudes and Spectra determined at the Har- vard College Observatory under the direction of Prof. E. C. Pickering. Quarto, vi-f 142 pages. Published 1911. Price $2.00. This work is based on 254 plates of 37 different fields, taken with the Sheep- shanks equatorial coude of 12 inches aperture and 20 feet focal length. The rela- tive parallaxes of 52 stars especially selected for observation, and of 242 others chosen as objects of comparison, have been determined. Every precaution was taken to eliminate systematic error; and the discussion of the results for the com- parison-stars indicate that the residual errors — whether depending upon a star's position, magnitude, or spectral type, or on the season of the year at which obser- vations were made — can not exceed a few thousandths of a second of arc. As regards accidental errors, the results appear also to be of high precision. The con- Astronomy 25 ditions suitable for obtaining the most accurate results for a given amount of work expended are next discussed, and, later, the astrophysical conclusions derivable from the data for the principal stars. Detailed tables of the numerical results of observation conclude the volume. No. 43. Peters, C. H. F. Heliographic Positions of Sun-Spots, Observed at Ham- ilton College from i860 to 1870.

The tables give the position of each spot referred to the center of the disk, the deduced heliographic latitude, the longitude from the node, and the heliographic longitude. For each day on which Peters observed, the angular distance between the prime meridians of the systems of Carrington and Peters is given. No. 86. Peters, C. H. F., and E. B. Knobel. Ptolemy's Catalogue of Stars, A Revision of the Almagest. Quarto, iii-l-207 pages. Published 1915. Price $3.50. The Catalogue of Stars, made by Hipparchus, transmitted by Ptolemy, and commonly called Ptolemy's Almagest, is the first and most ancient known manu- script which gives a description of the heavens of sufficient exactness to admit of comparison with modern observations. For many centuries it was practically the only record of positions of the stars which the world possessed, and it has accord- ingly been a subject of many researches and investigations. About 1876-77, Dr. C. H. F. Peters, of Hamilton College, realizing the import- ance of verifying the exactitude of the Catalogue, begun the studies which led up to the present volume, calculating, from modern observations, the longitudes and latitudes of all of Ptolemy's stars, embracing every probable star near Ptolemy's positions, corrected as far as possible for proper-motion. At almost the same time when Dr. Peters began his labors, Mr. Edward Ball Knobel, of the Royal Astronomical Society of London, took up this work on nearly the same lines, and for a considerable time the two continued their labors quite unknown to each other; but being fortunately brought into communication, a plan of cooperation in the enterprise was agreed upon. Before any progress was ef- fected, however, Dr. Peters died, in 1890. But his executors placed his manu- scripts and notes at the disposal of Mr. Knobel, who completed the work embodied in the present publication. No. 250. Knobel. Edward B. Uliigh Peg's Catalogue of Stars, revised from all Persian Manuscripts existing in Great Pritain, zvith a Vocabulary of Persian and Arabic words. Quarto. In press. From the second century, when Ptolemy published his Almagest, to the middle of the fifteenth century, there exists no catalogue of stars from original observa- tions. In the year 1437 Ulugh Beg published his astronomical tables entitled "Zig Ulugh Beg," which contain a catalogue of Ptolemy's stars, the positions of which were re-determined from original observations made at Samercand. Ulugh Beg was the last and perhaps the most distinguished representative of Arabian as- tronomy, and his catalogue is of unique interest, not only on account of its originality, but as it is the only record of the heavens v/e possess between the second century and the end of the sixteenth century when Tycho Brahe made his observations. In 1879 E. B. Knobel pubHshed a translation of the catalogue from a Persian manuscript of Ulugh Beg. Some time after this the late Dr. C. H. F. Peters, of Hamilton College, devoted much attention to the subject, but he confined ' his researches mainly to the printed editions of Hyde, Tharpe, and Baily. He com- puted f rom^ modern catalogues the positions of the identified stars for the epoch, thus affording sound means for determining the errors of the catalogue. 26 Astronomy The libraries of the British Museum, the India Office, and the Bodleian are particularly rich in Persian manuscripts of Ulugh Beg. The present work em- braces the results of Mr. Knobel's investigation of 23 or 24 Persian and Arabic manuscripts, including three manuscripts partly collated by Dr. Peters in Paris. The object has been to make the work as exhaustive as possible, but it is regretted that the war has prevented a complete collation of the manuscripts possessed by the Bibliotheque Nationale at Paris. No. 161. MouLTON^ F. R., in collaboration with Daniel Buchanan^ Thomas Buck, Frank L. Griffin, William R. Longley, and William D. Mac- MiLLAN. Periodic Orbits. Quarto. In press. A large part, though not all, of the periodic orbits treated in this book belong to the problem of three bodies. The first chapter contains certain theorems on implicit functions, the solutions of analytic differential equations, and a new treat- ment of linear homogeneous and non-homogeneous differential equations having periodic coefficients. The second contains a treatment of elliptic motion by the methods which have more general application. This is the simplest astronomical problem in periodic orbits. Certain additional methods are illustrated in the third chapter on the spherical pendulum, with new developments of certain elliptic func- tions. The fourth chapter treats of periodic motion about an oblate spheroid with applications to the motion of Jupiter's fifth satellite. The fifth chapter is devoted to a complete discussion of oscillating satellites in both two and three dimensions, in the case in which two of the bodies are finite and moving in circles, while the third is infinitesimal, and in which the centers of libratioti are collinear with the finite masses. Chapter VI is a treatment of the same problem by another method having important advantages in certain cases. Chapter VII is a discussion of the problem when the finite bodies move in elliptical orbits. Chapter VIII is a gen- eralization of Lagrange's collinear solutions of the" problem of three bodies to the general case of n bodies. Chapter IX is that of Chapter V for the equilateral triangular points of libration. Chapter X treats of the motion in the case in which two masses are equal, the third infinitesimal or finite, and the three always occupy- ing the vertices of an equilateral triangle. Chapter XI treats of satellites and in- ferior planets with application to the lunar theory. Chapter XII treats of superior planets. The problem of Chapter XIII is similar to that of Chapter XI, except that there are four or more bodies. Chapter XIV treats of the orbits of many small masses revolving around one large one. In all cases the existence of the periodic solutions is proved, methods of practically constructing them are given, and numerical illustrations are often added. Xo. 247. Barnard, E. E.

Factor Table for the First Ten Millions, containing the smallest factor of every number not divisible by 2, 3, 5, or 7 between the limits 0 and 1001/000. Folio, xiv-|-476 pages. Published 1909. Bound in leather and buckram $20.00 Unbound $18.00 This table furnishes the smallest divisor of every number up to the limit 10017000. The multiples of 2, 3, 5, and 7 are not listed as being easily obtainable from inspection. At the same time the failure to find a given number in the table is evidence that it is a multiple of one of these numbers. The omission of such numbers greatly reduces the bulk of the tables and adds very slightly to the com- plexity of the arrangement. A list of smallest divisors really serves to find all of the divisors of a number, for one may divide out the smallest factor as listed in the table and then proceed to obtain the smallest divisor of the resulting quotient. This process may be con- tinued until a quotient is obtained which is a prime. Factor tables for the first nine millions have already been published, but are for the most part unobtainable. The tables herewith published have been com- pared, entry for entry, with the previously printed tables and what is believed to be a complete list of errors is also given in the Introduction. The tenth million has been checked against a table in manuscript by Kulik deposited in the Vienna Academy of Sciences. Comparison with all of these tables has been made five times (six for the first three millions). The tables were printed by photographic methods which are believed to eliminate many errors which commonly occur by the falling out or breaking off of tj'pes. The problem of finding the factors of a given number is important in itself and is constantly met with in the theory of numbers and in the theory of groups. The allied problem of finding the number of primes between given limits makes a reliable list of primes of the first consequence. This list can now be made as far as the first ten millions, it is believed, with absolute confidence. Computations of the number of primes in the successive millions, and indeed in shorter intervals, tally exactly with the counts made from these tables as far as these counts have been made. No. 165. Lehmer, Derrick N. List of Prime Numbers from i to 10006/21. Folio, xvi+133 pages. Published 1914. Price $5.00. Until the completion of the author's Factor Table for the first ten million num- bers the construction of a reliable list of primes was impossible, owing to the numerous errors still undetected in the old tables of factors. The list of primes herewith published is taken from the corrected tables of factors and has been checked by comparison with the results of the count of primes made independently of factor tables by Meissel and Bertelsen. The number of primes in each successive thousand as counted by Glaisher has also been compared with the number obtained from the list. The results indicate a very high degree of accuracy for the list. The successive primes are arranged in columns of one hundred, there being fifty columns to the page. Each page thus serves to list five thousand primes. The total number of pages is 133, and therefore the total number of primes listed is 665,000. The page is identical in size with the page of the Factor Table. The arrangement enables one to tell at a glance the rank of any particular prime and the number of primes between any two given limits. 27 28 Mathematics No. 78. Shaw, James Byrnie. Synopsis of Linear Associative Algebra: A Report on its Natural Development and the Results Reached up to the Present Time. Quarto, 145 pages. Published 1907. Price $1.50. This synopsis aims to present in a synthetic way the results, up to the date of publication, of various methods of studying linearly distributive and associative operation. The abstract theory of such operations is the intent of the book. Under this head are included matrices, linear substitutions, bilinear forms, vector algebras, quaternions, and the general theory of operations. The main results of numerous memoirs on these subjects are put into organic relationship and some further results are deduced. No. 120. Decker, Floyd F. The Symmetric Function Tables of the Fifteenthic. Quarto, 21 pages. Published 1910. Price $1.25. This publication presents the table of symmetric functions of the equation of the fifteenth degree. Similar tables of equations of lower degrees have previously been published, references to which are given, together with a list of corrections of misprints found in some of them. The use of the tables is exhibited by the solution of a numerical equation and by the calculation of a resultant of two equations. The publication contains also a historical sketch, compiled from original sources, of the formulas connected with the calculation of symmetric function tables, which may not only give an appreciation of the development of the subject, but which will be useful in calculating tables of higher orders. No. 151. Stager, Henry W. A Sylow Factor Table of the First Twelve Thousand Numbers, giving the possible number of Sylow sub-groups of a group of given order between the limits of o and 12000. Quarto, xH-120 pages, 1 plate. Published 1916. Price $4.50. The main purpose of this table is to furnish direct information as to the possible number of sub-groups of a group of given order under Sylow's Theorem, "If is the highest power of a prime, p, which divides the order of a group, G, the number of sub-groups, H, of order p<^ is congruent to unity, modulo pf These sub- groups of order p<^ are called Sylow sub-groups. Each number is expressed as the product of powers of primes, and for each prime factor greater than 2 the values of k, other than zero, of all divisors of the number of the form p{kp-\-\) are given. Those values of k, other than zero, such that the number is identically equal to p{kp-\-\), are indicated by a star. In addition, a list of those numbers which contain no factors of the form p{kp-\-\), ^ > 0, is given, so arranged that the number of such numbers between any two limits less than 12230 is easily ob- tained. The table was constructed independently by two different methods, and the results compared for errors. No. 245. Hedrick, Henry B. Interpolation Tables or Tables of Proportional Parts, containing the products to the nearest unit of all numbers from I to 100 by each hundredth from o.oi to o.gg and of all numbers from I to 1000 by each thousandth from o.ooi to o.ggg. Folio. In press. These are essentially tables of proportional parts to hundredths and to thou- sandths, or multiplication tables of decimal fractions to two and to three places. They give the products to the nearest unit of all numbers from 1 to 99 by each hundredth from 0.01 to 0.99 and of all numbers from 1 to 1000 by each thousandth from 0.001 to 0.999. They are intended for use in multiplication where the product is required to no more significant figures than the smaller factor contains, as is usually the case in interpolation or in the multiplication of decim.al fractions which are given to three significant figures only. They give what is contained in Crelle's Multiplication Tables, but in a more compact and convenient form, when the product is not required to more places than the factors. The advantages over Crelle's tables are that the products are given only as far as needed and so the computer does not have to "point off," nor cut off part of the product. He does not have to notice if the omitted part is more or less than 0.500 in order to adjust the last figure of the result. Mathematics 29 These tables give the result directly and to the nearest unit. Instead of having to find the required product at the intersection of a line and a column, as in other tables — in using these tables the eye has to travel only in one direction at a time, first in a column, stopping at the second factor or the nearest number less than the second factor, and then along this line to one of the outside columns v/here the required product is found. There is a great economy of space which makes the tables very much easier and more rapid in use. They omit all unnecessary numbers of a series of consecu- tive numbers which give the same product. The great economy of space can be judged from the fact that only fourteen pages, instead of the one hundred pages in Crelle's tables, are required for the 200 tables from 0.001 to 0.200. These tables are more convenient and more accurate than a slide-rule of the same capacity. The two-place tables (three pages) are printed separately on heavy paper. ENGINEERING. No. 66. Goss, W. F.

A study based upon experimental investigations concerning the effect of changes in steam pressure upon the efficiency of steam locomotives. A basis for discussion is given in the results of 100 locomotive tests arranged in six series, a definite boiler pressure being assigned to each series. The range of pressure was varied from 120 pounds to 240 pounds per square inch. The presentation includes a description of the research and of the means employed in its advancement; a discussion of diffi- culties in operating a locomotive under very high steam pressures; a statement of facts concerning boiler and engine performance under different pressures, concern- ing machine friction, and concerning the degree of efficiency attending the perform- ance of work at the draw-bar; and a concluding discussion with reference to the more general question of boiler pressure versus boiler capacity as a factor in eco- nomic operation. Four appendices present respectively a description of the locomo- tive experimented upon, methods and data derived from tests, general data concern- ing the weight of boilers, and a file of typical indicator-cards. No. 127. Goss, W. F. M. Superheated Steam in Locomotive Service. Octavo, v-f 144 pages, 6 plates, 88 text figures. Published 1910. Price $1.25. A study based upon recent foreign practice and upon experimental investiga- tions concerning the use of superheated steam in locomotive service. In the course of this study generous attention has been given German superheating locomotives. These have been inspected when in the process of manufacture, when in service upon the road, when in shops for general repairs, and when in roundhouses for routine attention. Observations thus made prove that superheated steam may be successfully used in locomotive service without involving mechanism which is unduly complicated or difiicult to maintain. The experimental investigations were conducted at the laboratory of Purdue University. They included forty-seven formal tests of an American-built locomotive. The boiler pressures emploj'^ed dur- ing these tests ranged from 120 pounds to 240 pounds. The results show the re- lation between the degree of superheat developed and the output of power, together with such other significant data as water and fuel consumption. Heat balances covering the performance of the boiler and superheater are given for eighteen tests. The results are compared with those which are presented by Publication No, 66, entitled "High Steam Pressures in Locomotive Service," for the purpose of showing the effect of superheated steam upon the power and economy of the locomotive. Many results are presented graphically. Four appendices present a description of tests, methods, data, etc. No. 79. DuRAND, W. F. Researches on the Performance of the Screw Propeller, Octavo, 61 pages, 85 text figures. Published 1907. Price $0.75. An investigation into the influence on screw-propeller performance of the three thief factors: (1) pitch ratio, (2) slip ratio, (3) area ratio. Forty-two model pro- pellers of 12-inch diameter were employed covering variation in pitch ratio from 0.9 to 2.1 and in area ratio from 0.18 to 0.72, each propeller being tested through a range of slip from 10 per cent to 40 per cent. Measurements were made permitting the determination for these model propellers of thrust, work absorbed, and effi- ciency. The reduced results are shown in various forms, tabular and graphical, and their application to problems of propeller design is discussed. Similar results arc also given for some 47 combinations of two propellers on one shaft, comprising various arrangements of the above propellers as to relative pitch ratio, distance apart, and aspect of blades. 30 CHEMISTRY AND PHYSICS.

In this paper the defects of many previously used methods for determining compressibility are explained, and new methods are suggested which are applicable to nearly all liquids and solids. With the help of these methods the compressibility of bromine, iodine, chloroform, bromoform, carbon tetrachloride, phosphorus, water, and glass have been determined by reference to mercury in most cases as far as 500 or 600 atmospheres. From some of these the compressibility of liquid chlorine has been inferred. Approximate determinations of the heats of compression of water and mercury have been made. A new manometer for calibrating high-pressure gauges is proposed. The compressibilities of the substances named above have been compared with regard to their relative decrease with increasing pressure. It is pointed out that usually the greater the compressibility the greater is its decrease with increasing pressure. No. 28. Richards, T. W., and R. C. Wells. A Revision of the Atomic Weights of Sodium and Chlorine. Octavo, 70 pages. Published 1905. Price $0.50. The investigation described in this monograph consisted of a very careful quantitative study of the three ratios involving the three substances— silver chlo- ride, sodium chloride, and metallic silver. An effort was made to test every opera- tion involved in the execution of the experiments with the greatest precision. Ex- traordinary precautions were taken in purifying all the substances used. The identity of materials obtained from many different sources was demonstrated in order to prove the adequacy of the methods of purification. Before weighing, all the substances were fused in vacuum in order to eliminate air and moisture. The conditions governing the irregularities attending chemical precipitation were studied more minutely than hitherto and the necessary precautions were applied. It was shown conclusively that Stas's silver must have been impure and that ac- cordingly his atomic weight of chlorine was in error by over 0.05 per cent, while his value for sodium was nearly 0.2 per cent too high. The new values are respec- tively 35.473 and 23.008, if silver is provisionally taken as 107.930, each figure being diminished by 0.046 per cent if silver is taken as 107.88. No. 56. Richards, T. W., and G. S. Forbes. Energy Changes Involved in the Dilution of Zinc and Cadmium Amalgams. Octavo, 68 pages, 10 figs. Published 1906. Price $0.50. The electrochemical and thermochemical properties of liquid amalgams were investigated with a view to the further understanding of chemically generated electromotive forces. Extraordinary precautions were taken against experimental errors. Zinc amalgams gave potentials lower than those calculated from the gas law (or law of concentration-effect) and cadmium amalgams gave potentials higher than those thus calculated. As the dilution with mercury is increased, the deviations diminish, and in the most dilute amalgams investigated the closest ap- proach to the law ever noted in the study of solutions was found. The temperature- coefficient of the potential of the cadmium amalgam cells was found to be almost identical with the tension increment of a perfect gas, while that of the concen- trated zinc-amalgam cell was shown to be greater. Preliminary thermochemical experimentation supported these conclusions, and all the experiments were studied in relation to the conclusions of Helmholtz and of Cady. A part of the work has since been verified by the less comprehensive investigation of Hulett and De Lury (J. Am. (Jicm. Soc.» SO, 1812 [1908] ). This investigation is continued in publication IIS. 31 32 Chemistry and Physics No. 61. Richards, T. W., and G. E. Behr. The Electromotive Force of Iron under Varying Conditions and the Effect of Occluded Hydrogen. Oc- tavo, 43 pages, 6 text figures. Published 1906. Price $0.25. The object of this work was to determine with great precision the electro- motive force of iron in contact with solutions of its salts, as a first step in the exact study of the very important phenomenon of rusting. It is shown that all previous investigations upon this subject were at fault because of inadequate pre- cautions as to the purity of the iron and the exclusion of oxygen from the system. Iron in various conditions was investigated and the effect of stresses was studied. If the normal calomel electrode is taken as having a single potential difference of 0.56, pure compact iron has a single potential difference of 0.15. Occluded hydrogen was found greatly to raise this value. The facts received brief theoretical discus- sion. This work has since been repeated and verified by others. No. 69. Richards, T. W., and A.

Octavo, 88 pages, 4 text figures. Published 1907. Price $0.50. This monograph includes four papers, one having been undertaken with the help of each of the four assistants named above. The first consisted of a study of the atomic weight of potassium essentially similar to that of sodium described in publication 28, with some further precautions contributing still more to accuracy. It was shown that Stas had made the same errors in the case of potassium as in that of sodium and that the real atomic weight of this element is to be taken as 39.114, if silver is 107.93. The second paper describes a precise study of potassium bromide. This yielded identically the same value for potassium as the chloride, leaving no doubt as to the true value of the atomic weight of this element. If silver is taken as 107.88, potassium becomes 39.096. The third paper deals with the synthesis of silver nitrate from pure silver and pure nitric acid. In the course of the work a new and convenient apparatus for quantitative evaporation involving quartz flasks was devised. The silver nitrate was fused until constant in weight; it was carefully tested for dissolved air, re- tained water, and ammonia, and nitric and nitrous acids. Only the second and third of these impurities could be detected by tests proved to be adequate, and these only in mere traces, less than 0.002 per cent in all. The outcome was that if nitrogen is taken as 14.008, silver must be taken as 107.880. The fourth paper concerns the atomic weights of silver and sulphur, which were evaluated by converting pure silver sulphate into silver chloride. The results showed that if sulphur is taken as 32.07, silver must be 107.88. No. 76. Richards, T. W., and W. N. Stull, F. N. Brink, and F.

Until this investigation was undertaken almost nothing was known about the compressibility of the elements. The monograph describes experiments carried out by the new method detailed in Publication No. 7. Thirty-five of the solid and liquid elements were investigated — enough to show that the compressibilities of the elements are distinctly related periodically with one another as well as with other properties such as volatility and atomic volume. Among the elements investi- gated, silicon was least affected by pressure, having a compressibility less than one-twentieth of that of mercury, and caesium was found to be the most compres- sible among the solid elements, having a compressibility about fifteen times that of mercury. Liquid chlorine was found to be about half again as compressible as this ; and other solid and liquid elements have values ranging between these extremes. No. 118. Richards, T.

Octavo, iv-l-72 pages, 12 text figures. Published 1909. Price $0.50. The connected investigations described in the two papers comprised in this mono- graph are a continuation of the research described in Publication No. 56. The Chemistry and Physics 33 object was to extend the study to elements possessing other valences and to study more accurately the phenomena investigated. The electromotive forces (and their temperature coefficients) of various cells containing amalgams of the eight metals named in the title were measured, with many precautions against experimental errors. Thallium and indium were found to behave in the same manner as cadmium, but in a much more exaggerated degree. Tin and lead were found to behave in the same manner as zinc, but likewise in a more exaggerated degree. It was shown that the greater part of these deviations from the concentration law may be explained by the heat of dilution of the amalgam, according to the equation of Cady. The temperature-coefficient of a cell of this type was shov/n to correspond closely with the requirement of this equation. The difficulties of the actual measurement of thermochemical data involving amalgams were emphasized, and many errors in the work of previous investigators were discovered. It was shov/n that the deviations from the simple concentration law in every case decreased as the dilution increased, so that upon reaching a concentration of 0.01 gram-atom per liter all the amalgams investigated behaved practically as ideal solutions.

The first paper describes a new method for determining the atomic weight of silver through the ratio of lithium perchlorate to the chloride on the one hand and the ratio of the chloride to silver on the other. A new method of purifying lithium salts is described, as well as new apparatus for effecting the change of the chloride into the perchlorate. Incidentally the atomic weight of lithium was determined anew and found to be nearly 1 per cent lower than Stas's value. If oxygen is taken as 16, the investigation yielded as its result Ag = 107.871 and Li = 6.939. The second paper contains a brief description of all the investigations concerning atomic weights which have been conducted in Harvard University, with a detailed chronological bibliography and a table comparing the results with the accepted inter- national values.

Octavo, vi-f352 pages, 20 text figures. Published 1907. Price $2.50. This publication describes an extended series of researches on the electrical con- ductivity of aqueous solutions through a v/ide range of temperature (18° to 306°). The special apparatus which had to be constructed for the purpose is fully described! The conductivity results obtained with seventeen different salts, acids, and bases at various concentrations are presented in detail ; and these results are discussed v/ith reference to the migration-velocities of the constituent ions and the degree of ionization and hydrolysis of the substances themselves. From the hydrolysis meas- urements the ionization constant of water is derived for temperatures between 0 and 306^ The general conclusions to which all these researches have led are presented m a comprehensive summary at the end of the work.

In this monograph are brought together the results of several years' work on the various lines of evidence bearing upon the "Hydrate Theory." One of the most 34 Chemistry and Physics important of these is the evidence furnished from the lowering of the freezing-point of water with which a salt crystallises and its power to lower the freezing-point of water when dissolved in that solvent. This is shown to be a strong argument in favor of the theory of hydration in aqueous solutions. The freezing-points of be- tween 1,200 and 1,500 solutions of more than 100 compounds were measured, and the results are here recorded. Experimental evidence was also obtained which showed that salts dissolved in alcohol frequently combined with more or less of that solvent, forming alcoholates. The theory of hydration in aqueous solutions thus becomes the theory of solvation in solution in general. The second part of this monograph deals with the absorption spectra of solu- tions from the standpoint of the hydrate theory. The absorption spectra were obtained with a grating spectroscope, and solutions both in water and in the alcohols were studied, also solutions in mixtures of the alcohols with water. The effects of concentration of the solution and of the presence of a dehydrating agent were tested; also the effect of adding varying amounts of water to the solutions in the alcohols. The results all fall in line with the hydrate theory, and can be interpreted in terms of no other conception thus far advanced. No. 80. Jones, Harry C, and C. F. Lindsay, C. G. Carroll, H. P.

This publication deals with conductivity and viscosity in mixed solvents. The conductivities of a large number of salts in water, methyl and ethyl alcohols, and acetone were studied, and the relation between these conductivities and the vis- cosities of the several solvents, including especially the mixed solvents. A large number of relations were brought out, showing that the viscosity of the solvent, or solvent mixture, is a prime factor in conditioning the conductivity of dissolved electrolytes. It was shown that the effect of one associated solvent on the association of another associated solvent, with which it is mixed, is to lessen its association. The minima in the conductivity curves obtained in mixed solvents were also explained. The bearing of the temperature coefficients of conductivity on the hydrate theory is discussed, and the meaning of negative temperature coefficients pointed out. The lowering of the viscosity of water produced by certain salts is considered, and the first satisfactory explanation of this important phenomenon given. No. 110. Jones, Harry C, and John A. Anderson. The Absorption Spectra of Solutions. Octavo, vi+110 pages, 81 plates. Published 1909. Price $3.50. This monograph deals entirely with the absorption spectra of solutions of cer- tain salts of cobalt, nickel, copper, iron, chromium, neodymium, praseodymium, and erbium in water, methyl alcohol, ethyl alcohol, and acetone; and in mixture* of water with the other solvents. The work recorded takes up the subject of the absorption spectra of solutions in a fairly comprehensive manner. Among the problems studied are the effect on the absorption of light produced by changing the concentration of the solution but keeping the total amount of colormg matter in the path of the beam of light constant; the effect of dehydrating agents; the absorption spectra ift methyl and ethyl alcoliols, as well as in water and in acetone, is also brought within the scope of this work. Some surprising results were obtained, especially with the salts of neodymium in the alcohols. It was found that neodymium chloride showed one set of bands in aqueous solutions, but some entirely new bands made their appearance in the alcoholic solutions. In mixtures of water with the alcohols both sets of bands came out simultaneously. The nature of absorption of Hght by solutions in general is discussed at some length. Heliotype reproductions of 81 plates of spectrograms are given, including about 1,200 solutions. All these data are explained with perfect ease by means of the general theory of solvation in solution, but a large number of the facts brought to light in this work are not explicable in terms of any other suggestion thus far advanced.

The results obtained from the study of about 3,000 solutions are herein recorded. The effect of the addition of free acids and foreign salts on absorption spectra show that chemical reactions are probably m.uch more complex than we usually suppose. It was found that solvents which do not absorb visible light may have a marked influence on the absorption of the dissolved substance. Definite solvent bands have been discovered for water, the alcohols, acetone, and glycerol. These bands are characteristic of each solvent, and the proof of their existence is regarded as strong evidence for the theory of solvation in solution. It is difficult, not to say impossible, to see how the solvent can produce such a marked effect upon the reso- nance of the vibrators in solutions unless it enters into some kind of combination with the dissolved substance. The evidence for the solvate theory having become so strong, a brief discussion of the significance of that theory is given. Itls shown that when we supplement the theory of electrolytic dissociation by the theory of solvation we have a satisfactory theory of solution. A fairly large amount of work was done on the effect of temperature on the absorption spectra of solutions, and the results are recorded. A bibliography of the publications from this laboratory on the solvate theory of solution is appended. No. 160. Jones, Harry C, and W. W. Strong.

The results of the study of three problems are herein recorded, and the ab- sorption spectra of a number of rare substances are mapped. Salts of dysprosium and samarium have spectra that are almost as interesting as those of neodymium. The spectra of a number of salts in a large number of organic solvents were studied and "solvent bands" were found for a number of the solvents used. Isomeric solvents showed different bands for a given salt. The second problem was the change in the spectrum which takes place as one salt of a metal is transformed into another salt. The effect of oxidizing agents on uranous salts was especially investi- gated Mild oxidizing agents oxidized the "hydrated" salt and left unaffected the alcoholated" salt— an example of selective oxidation. The effect of rise in temperature on the absorption spectra of solutions was also studied. By means of a c osed cell, devised for the purpose, temperatures as high as 195° were used with alcoholic solutions. The absorption bands widen with rise in temperature, colored solutions in general becoming more opaque. It was also found that the "water" bands of any given salt are more affected by rise in temperature than the "alcohol" bands ; showing that the hydrates are less stable with rise in temperature than the aicoholates. These are but a few of the many relations brought out by the work. No. 170. Jones, Harry C, and A. M. Clover, H. H. Hosford, S. F. Howard, C. A. JACOBSON, H. R. Kjreider, E. J. Shaeffer, L. D.

' The work recorded in this monograph was undertaken especially because, when reference is made to the literature for the conductivity of any electrolyte at any given temperature, and for the temperature coefficients of conductivity, it is fre- quently difficult to find what is desired; or, if found, the data may be so discordant 36 Chemistry and Physics that it is impossible to decide as to the true conductivities and dissociations in question. Since the magnitude of the dissociation of any electrolyte is fundamental to its scientific use in chemistry, it is desirable that such data should be made avail- able over the range of temperature most frequently used in the laboratory. With this idea in mind, the work has now been continued until it represents more than twenty years' continuous labor for one man, about 40,000 conductivity measurements having been made. The conductivities and dissociations of about 110 of the more common salts have been worked out from zero to 65 degrees, and over a range in dilution extending from about the most concentrated solution that could be used to the dilution of complete dissociation. The temperature coefficients of conductivity have been calculated in both conductivity units and per cent. Similar data have been obtained for about 90 of the more common organic acids, and their constants have been calculated by means of the Ostwald dilution law. No. 180. Jones, Harry C, assisted by C.

The effect of one hydrated salt on the hydration of another hydrated salt was worked out with a number of pairs of salts. The dissociation of a number of salts was determined by the freezing- point and conductivity methods. It was shown that the atoms or ions with the smallest volumes have the greatest hydrating power. The relation between hydrat- ing power and electrical density is discussed. The dissociation in the alcohols was determined by the improved conductivity method. Three investigations had to do with the physical chemistry of glycerol as a solvent. The conductivity and viscosity of solutions in glycerol as a solvent were studied at different temperatures, glycerol being a liquid solvent with enormous vis- cosity. The temperature coefficients of both conductivity and viscosity in glycerol were very great. The salts of ammonium and rubidium were found to lov/er the viscosity of glycerol. The explanation of this phenomenon, offered by Jones and Veazey in monograph No. 80, for aqueous solutions, was found to apply equally well for solutions in glycerol as the solvent. No. 190.

Octavo, vii+93 pages, 22 plates, 44 text figures. Published 1913. Price $2.00. A form of closed apparatus was devised and used for studying the absorption spectra of aqueous solutions up to 200°. It was found that the absorption bands widen with rise in temperature. The effect of dilution on the absorption spectra of solutions was also investigated over a range of dilution varying from 1 to 500. The absorption increased with the concentration, especially towards the red end of the spectrum. A radiomicrometer was built and used for studying absorption spec- tra quantitatively. This permitted work at much greater wave-lengths than was pos- sible by means of the grating spectroscope and photographic plate. The former was limited to X 7,600, while the latter can be used as far as X 30,000, and even farther. The effect of dilution was also studied quantitatively by means of the radiomicrom- eter, and interesting and important results were obtained in reference to the effect of dilution on the nature and position of the transmission bands. It was found that "free" water had a different absorption from "combined," and this was regarded as further evidence for the solvate theory of solution. The absorption spectra of a fairly large number of salts were mapped by means of the radiomicrometer. Chemistry and Physics 37 No. 210. Jones, Harry C, with E. J. Shaeffer, E. P. Wightman, P. B.

Price $1.75. In the investigations recorded in the above-named publication it was found that solutions of non-hydrated salts are equally absorbent with pure water, except at the bottoms of the bands where the solutions are more opaque. Solutions of hy- drated salts are more transparent than pure water, showing that combined water has less absorption than free water. This is regarded as strong evidence in favor of the solvate theory of solution. The work on the conductivities and dissociations of the organic acids in both water and alcohol has been extended, and some results of interest, especially in alcohol, are included in this volume. The work in mixed solvents, the earlier results of which have already been published in Nos. 80 and 180 of this series, has been extended. An elaborate study has been made of a few salts in binary mixtures of ethyl alcohol and water, of acetone and water and in ternary mixtures of acetone, glycerol, and water, and the results are recorded in this monograph. Work bearing directly or indirectly on the solvate theory of solution has been in progress for about 15 years in the Chemical Laboratory of the Johns Hopkins University; and many papers dealing v/ith the subject have been published in American, German, French, and English scientific journals. The Carnegie Institu- tion of Washington, which has assisted the work with grants during much of this time, has also published nine monographs on various phases of the subject. Some of the more important points established in all of this work are summar- ized in the last chapter of the present publication. No. 230. Jones, Harry C, with P. B. Davis, W. S. Putnam, E. J.

Octavo, vii-f 175 pages, 3 plates, 21 text figures. Published 1915. Price $2.00. The viscosities of solutions of csesium salts in mixed solvents and in mixtures of the associated liquids, v/ater, formic acid, and acetic acid were studied in their bearing on the theory of viscosity proposed by the principal author some years ago. The dissociation of salts in formamid was measured in connection with the relation between the dissociating power of solvents and their dielectric constants. A new grating spectroscope and radiomicrometer were employed in working out the ionization constants of indicators and satisfactory results v/ere obtained for a few of the indicators more commonly used in analytical work. The relative chemical activity of free and of combined water was investigated in connection with the velocities with which they saponified an ester and hydrated acetic anhydride. The conductivities of a number of the more common organic acids in ethyl alcohol and in several of the less common salts in water were measured. It was found that combined water probably had less dissociating power than free water. The absorption and adsorption of potassium chloride by soils are of both scientific and technical importance. Potassium chloride is partly absorbed or combined chemically with the soil particles and partly adsorbed or in a state of physical union with the particles of the soil. 38 Chemistry and Physics No. 35.

A spectroradiometric investigation of the most important groups of chemically related compounds to determine what effect certain groups of atoms have upon the transmission of radiant energy. Part I describes the absorption spectra of 135 substances, including solids, liquids, and gases, many being organic compounds. The observations extend from the visible spectrum to wave-length 0.015 mm. in the infra-red. Many absorption bands were identified with certain groups of atoms, e. g., with CHa, NH4, NO2, OH, NCS, etc. Five appendices are added, which deal with subsidiary problems, such as radiometers, absorption of solids in solution, etc. Part II gives the results of a radiometric investigation of the emission spectra of various metals in the carbon arc and of gases in a vacuum tube.

In Part III the results obtained in Part I are applied to gain information with regard to the molecular struc- ture of minerals containing oxygen and hydrogen in the form of "water of crystal- lization" and of "water of constitution." It is shown that the spectra of minerals containing "water of crystallization" have absorption bands identical with those of water, while "water of constitution" shows no such bands. In Part IV are described the reflection spectra of various minerals, such as, for example, sulphides, sulphates, silicates; also solutions of these substances and metals not heretofore examined. These investigations extend to wave-length 0.015 mm. in th€ infra-red, and many of these substances are shown to have bands of strong se- lective reflection. Five appendices are added, in which are described the emission spectrum of carbon disulphide, a new radiomicrometer, methods of blowing quartz fibers, and a discussion of the possibility of the observed radiation from the moon being due, in part, to selectively reflected solar energy.

Part V gives the reflection spectra of various substances, including sulphides, oxides, carbonates, and silicates not previously obtainable. In the sulphides and carbonates the long-sought-for shift of the maximum of the reflection or absorption band with change in atomic weight of the basic element (which is joined to the CO2 or SO4 radical), which was described in No. 65, was definitely established. A minute ex- amination of the reflection bands of quartz (crystalline and amorphous glass) and of carbonates was made; and by means of residual rays the reflection spectra are extended to the remote parts of the infra-red to wave-lengths 0.03 to 0.04 mm. In Part VI the transmission spectra of various solutions, of colloidal metals, and of colored glasses arc described, and the effect of special groups of atoms on radiant energy is considered in detail. Part VII is an extension of Part II and describes the arc and spark spectra of metals in hydrogen, to verify the previous work, which showed that no strong emission lines exist in the deep infra-red. New and impor- tant results were obtained on the vapors of the carbon arc. The radiation of the Rubens thermopile to a vessel of liquid air was investigated, showing that the pile is a very complete radiator and absorber of radiant energy. The Nernst glower is shown to have a discontinuous spectrum at low temperatures, which becomes con- tinuous at high temperatures. Various solids (many heated electrically, like the Nernst glower) are shown to have discontinuous spectra with emission bands which are as sharp as those of gases. The emission of the new metals (used in incandescent lamps) was investigated, and it was found that the so-called "constants" of radiation are really functions of Chemistry and Physics 39 the temperature and the wave-length. From a consideration of the reflecting power it is shown that metals must emit selectively in the visible spectrum. The radiation from selectively reflecting bodies, with special reference to lunar radiation, is again discussed; also the effect of the surrounding medium upon the emission of a substance. Three appendices are added, the most important one being on instruments and methods used in radiometry, in which the radiometer, thermopile, radiomicrometer, and bolometer are compared, both historically and by means of experimental data. In each volume the author indicates problems requiring further investigation as well as new fields of research. No. 164. CoBLENTz, W. W. A Physical Study of the Firefly. Octavo, 47 pages, 1 plate, 14 text figures. Published 1912. Price $0.50. In this paper are discussed the production, the composition, and the functions of the light emitted by fireflies. Luminous efficiency, candle-power, radiation, and temperature measurements are given ; also data on the fluorescent substance found in fireflies. The lights of various species of fireflies and of a standard lamp were photographed, and the densities compared by means of spectrophotographic photom- etry. In this manner the spectral energy curve of the light of the firefly was deduced from a knowledge of the spectral energy curve of the standard lamp. It is shown that the color of the light of the firefly is not a subjective phenomenon, the maxi- mum emission of the Pyrophorus noctiluctis being at 0.538/a, Photuris pennsylvanica 0^7?

The volume gives an account of the apparatus used in recording sounds and of the methods applied in obtaining speech curves. A chapter on qualitative analysis indi- cates how phonetic facts may be read directly from the speech curves without meas- urement. It is also explained how such fundamental factors of speech as melody, duration, and amplitude can be obtained from the curves by simple methods of measurement. The method of harmonic analysis is carefully considered, the theories of vowel productions are discussed, and detailed examples of vowel analysis are given. No. 57. Washington, H. S.

An investigation of the relation between the feldspars of the lime-soda series undertaken partly in an endeavor to settle an old question of great petrological interest and partly to establish the fact that minerals in solution with one another differ in no essential particular from other solutions and obey the same funda- mental lav/s. The materials are chemically pure feldspar types prepared in the laboratory; the methods are those of quantitative chemistry, physics, and physical chemistry, and the field covers the entire temperature range of feldspar formation up to 1540° C. Many of the phenomena occurring at these extreme temperatures differ widely from those commonly observed at ordinary temperatures and are thus broadly interesting from the viewpoint of the properties of matter. In particular, it was discovered that among the minerals it is not uncommon for the solid state to persist for hours or even days at a temperature considerably above the melting-point, a phenomenon which has never been observed before.

Price $1.25. An account of a new determination, with the nitrogen thermometer, of the funda- mental scale of temperatures, beginning with 400° C. and extending to 1550° C. Its purpose was partly to increase the accuracy of the existing (Reichsanstalt) scale, which reaches only to 1100°, but more particularly to extend the scale beyond this temperature as far as it should prove practicable to go without serious sacrifice of accuracy. It proved possible to establish the melting-point of pure palladium (1549.5*) with a probable uncertainty of no more than 2°. Two bulbs were used, one of platinum containing 10 per cent of iridium, the other of platinum containing 20 per cent of rhodium. The latter material proved to be better suited to the purpose than any which has hitherto been tried. In the experi- mental development of the problem, the errors of the older (Reichsanstalt) instru- ment, so far as known, were reduced to about one-fourth of their former magnitude. The apparatus and its limitations, together with all the results obtained with it in a period of nearly five years, are described in considerable detail. No. 158. Wright, Fred. Eugene.

The factors underlying the determination of any given optical property are discussed in detail, and the attempt is made in each case to ascertain the absolute accuracy attainable. No. 40. Barus, Carl. Nucleation of the Uncontaminated Atmosphere. Octavo, xn-f-152 pages, 104 text figures. Published 1906. Price $1.00. This book contains as its chief feature a record of the dust content of the air at Block Island, Rhode Island, in comparison with identical observations made at the same time in Providence, Rhode Island, throughout the winter of 1904-1905. In winter the former locality is relatively uninhabited and is surrounded by water on all sides. It is shown that the time distribution of nuclei in both places is qualitatively the same, although in Providence it is four to ten times larger quantitatively. In the introductory chapters a number of independent correlative experiments are in- cluded, referring to condensation on ions and on the vapor nuclei (colloidal nuclei) of dust-frec wet air, to the production and distribution of persistent nuclei pro- Chemistry and Physics 41 ducible by the X-rays, to the penetration of radium radiation through different media and different distances, etc., all interpreted by measuring the apertures of the coronas of cloudy condensation. The corresponding nucleation is computed as shown in the author's earlier papers. No. 62, Barus, Carl. Condensation of Vapor as induced by Nuclei and by Ions. Octavo, x+164 pages, 66 text figures. Published 1907. Price $1.50. The purpose of this book is the development of a capacious fog-chamber, efS- cient enough to capture the ions and the vapor nuclei of dust-free wet air by con- densation, to the extent in which their number per cubic centimeter may be measur- able by aid of the coronas of cloud particles. As the apertures of the coronas eventually become very large, approaching 60°, and a reasonable exhibit of coronal colors is essential for identification, the need of a large apparatus is apparent. Equa- tions are deduced for the practical treatment of the variables involved. Experiments made with water and alcoholic vapors in different gases establish the nature of the vapor nuclei of dust-free media. In continuation of the atmospheric work of the preceding report, a comparison is made of the ionization and the dust contents of the atmosphere in a series of observations extending over several months ; also of the ionization of dust-free wet air in the lapse of time, as exhibited by the fog-chamber. No. 96. Barus, Carl. Condensation of Vapor as induced by Nuclei and by Ions. Report III. Octavo, vi+139 pages, 48 text figures. Published 1908. Price $1.25. After summarizing the thermodynamic equations which determine the efficiency of the plug-cock fog-chamber, the author continues his work on the changes of the incipient nucleation (ionization) of dust-free wet air in the lapse of time. No periodic variations are detected, but the vapor nucleation changes about 2 per cent per degree centigrade. A new series of experiments is then undertaken to standard- ize the coronas of cloudy condensation in dust-free air in terms of the nucleation represented. This is done both by the old method of diffraction from a single point of light and by a new method in which the coronas from two sources are brought into contact. The results obtained are next applied for exhibiting the distribution of ions and vapor nuclei in dust-free wet air in relation to size. Finally, a systematic study is made of the behavior of residual water nuclei, /. e., nuclei of pure water obtained from the evaporation of fog-particles precipitated on vapor nuclei or on ions in dust-free wet air. More nuclei are lost after evaporation in the cases of ions as compared with the cases of vapor nuclei, and the initial evaporation is always preponderating in its destructive effect. No. 96.

In the first part of this report the author treats the properties of the nuclei of water vapor, showing among other things that they persist longer in proportion as the evaporation of the parent fog-particles is more rapid. The standardization and efficiency of fog-chambers are then taken up, the results being tested by the coronas of monochromatic light (mercury vapor). These results have a direct bearing on the theory of coronas. Some space is given to the displacement of ions by exhaus- tion, as evidenced by the occurrence of maxima of ionization in the fog-chamber. Finally, the attempt is made to standardize the coronas by the aid of Thomson's elcc" tron, the charge of which is known. Independent methods, using either the velocity of the ions or the decay constants, are tested for this purpose. The voltaic poten- tial difference between conductors separated by an ionized medium is investigated. No. 149. Barus, Carl. Production of Elliptic Interferences in Relation to Inter- ferometry.

Price $1.00. In the cases of coronas there is a marked interference phenomenon superposed on the diffractions. This suggested the present investigation, which aims at a sim- 42 Chemistry and Physics plification of the effect in question by bringing two complete component diffraction spectra, from the same source of light, to interfere. Many ways are shown to be available, the methods being either direct (as discussed in Chapters II and III, where a plane mirror immediately behind the grating returns reflected-diffracted and dif- fracted-reflected rays) or indirect, using the devices of Jamin, Michelson, and others (Chapters IV and V). In Chapter I a modification of Rowland's apparatus, suitable for plate gratings, is described. The direct method gives equidistant fringes, duplex in character, but rigorously straight throughout the spectrum, their distances apart and inclination being measurable by ocular micrometry. Lengths and small angles are thus subject to micrometric measurement. In case of the indirect method, the half-silvered plate is replaced by the grating; the fringes are, as a rule, approxi- mately elliptic (confocal) throughout the spectrum, and the fringes again partake of both a drift and a radial motion when the interferometer adjustment is altered. Drift and radial motion may be regulated in any ratio. The theory of the subject is worked out, in so far as it bears on the practical results obtained. Part 11^ is in the main a direct continuation of the preceding and refers chiefly to applications of the displacement interferometer. The first section describes cer- tain interferences obtained when two originally coplanar halves of a reflecting grating move normally to the ruled surface, the line of separation being parallel to the rulings. It suggests the occurrence of interference rings when the source of light in the case of coronas is not simple but a doublet of two interfering beams, and that, for layers of fog-particles whose distance apart is commensurate with wave-length, interferences should be superimposed on the coronal diffractions as actually observed. Certain subsidiary investigations follow : The effect of the thickness of the cloud layer on the type of corona obtained ; on the efficiency, ccBt. par., of different sizes of fog-chambers; on the rate of decay of different sizes of nuclei, etc. The dis- placement equation adduced in the first report is rigorously tested, a method for measuring the dispersion of a fragment of plate glass being devised for the purpose. Finalty, a type of interferometer specially suited for displacement work is construc- ted. This instrument is thereupon put to the test in the endeavor to measure rela- tions connected with the adiabatic expansion of gases, and other phenomena in which instantaneous registry by aid of the index of refraction of the gas is serviceable. Part III records a variety of investigations made at widely different times, but in all of which the displacement interferometer was used as a basis of measurement. No. 186. Barus, Carl. Diffusion of Gases through Liquids, and Allied Experi- ments. Octavo, vi+88 pages, 38 figs. Published 1913. Price $1.00. In 1900 the author began a series of experiments to determine the rate at which gases diffuse out of a submerged Cartesian diver through water. The method proved to be remarkably sensitive and the results striking. In the present volume the method is perfected, with a view to completing the measurements within a reasonably short interval of time. Diffusions of air, hydrogen, and oxygen into each other, through water and a variety of solutions, are investigated in detail and the diffusion constants determined. It is shown that a method of exploring the internal channels or physical pores of liquids is probably in question. In the course of the work a number of other applications are included; for instance, the disk of an absolute electrometer is floated on a Cartesian diver subm.erged in hydrocarbon oil, and the potential is measured absolutely by the pressure needed to just suspend the diver in the liquid. All these results are given in full and in most cases charted, the curves being often of singular complication. It is shown why diffusion frequently occurs against the apparent pressure gradient.

Price $1.00 This volume contains applications of the displacement interferometer to subjects largely depending on minute angular measurement. Although a location free from tremor and irregular temperature variations could not be found, the development of methods of the kind in question was quite feasible; and v;ithout attempting to push them to a limit, their ranges of application could be fully investigated. Chemistry and Physics 43 Among the subjects selected for treatment was the horizontal pendulum. In Chapter I certain available forms of the pendulum, with and without a float, are considered and tested as to their discrepancies, through long lapses of time, by a reflection method. Thereafter the interferometer itself is used, a serviceable method of application worked out and the range of application studied through many months. With a relatively very wide scope (several seconds of arc) there should be no difficulty, under proper surroundings, of measuring changes of in- clination as small as 3X10-^ seconds of arc per interference ring. In Chapter II an attempt is made to use this interferential horizontal pendulum, for the measurement of the gravitational attraction of two parallel disks. What was obtained, however, was a definite repulsion of the disks, decreasing with their distance apart and appreciable even within 1.5 mm, of this distance. Chapter III is introduced as a severe test on the interference equation employed, for the case of path differences resulting when glass columns as much as 10 inchei long are inserted in one of the component beams of the displacement interferometer. It appears that the constants of any dispersion formula may be obtained directly from these observations. In Chapter IV a number of incidental experiments, on allied subjects, have been grouped together. The possible bearing of certain disk colors of circular gratings, on the somewhat similar phenomenon in coronas, is discussed, as well as the per- formance of the easily available film grating to replace the ruled glass grating, for purposes of displacement interferometry, from a practical standpoint. An interest- ing case of regular reflection and refraction of scattered light, bearing on the X-ray phenomena, is also discussed. In Chapter V, finally, following the suggestive experiments made in an earlier report, the displacement interferometer is directly applied to the quadrant elec- trometer. The sensitiveness obtained in this way should be of the order of a millionth of a volt per vanishing interference ring. No. 249. Barus, Carl. The Interferometry of Reversed and Non-reversed Spec- tra. Octavo, 158 pages, 99 figures. Published 1916. Price $1.50. In this volume the author has endeavored to generalize the classic experiments in the diffraction of light, by bringing two spectra from the same source to inter- fere under a great variety of conditions. The spectra may be identical and super- posed throughout their extent, or one may be expanded longitudinally, or reversed on a transverse axis, or inverted on a longitudinal axis, relatively to the other. An abundance of new phenomena are thus obtained, some of them useful. The interfering pencils may have any relation to each other, either running in parallel at any distance apart or crossing each other at any angle. Though spectrum inter- ferences are usually obtained, some of them are achromatic. Experiments of this character make up the first seven chapters of the book. The remaining six chapters are devoted to new investigations with the displacement interferometer, such as the use of curvilinear compensators, the dispersion of air, etc. No. 135. Baxter, G.

The investigation covers the effect of a magnetic field upon 1,120 lines in the iron and titanium spectra between the limits A 3660 and A 6743, with discussion of experimental methods, brief historical treatment, and full discussion of the results with reference both to existing theories of the Zeeman effect and the effect of other physical conditions upon spectra. A large portion of the range of wave-length examined has not been covered in previous work with the magnetic field, while the high dispersion employed and the attention to the weaker lines give much new data for those parts of the spectrum already treated to som.e extent. The large range of wave-length has made it possible to study the change of the average separation of Zeeman components with increase of wave-length, bringing out the important result that for both spectra the average separation increases with the square of the wave- length. The material shows clearly how generally the separations, both simple and complex, are related to a fundamental interval involving the accepted value of e/m. Fifty-seven lines having five or more clearly resolved components are examined with respect to the commensurability of their separations. Among these complex lines many cases of magnetic duplicates are pointed out. This indicates a similarity of the Chemistry and Physics 45 vibrations producing such lines which will aid in the consideration of their behavior under other physical conditions. An extended comparison is made of magnetic separation and pressure displacement for the lines of iron and titanium, showing to what degree a correspondence exists. Examples of dissymmetry in separation are noted, including the small dissymmetry of triplets and dissymmetries so large as to be classed as abnormal separations. No. 198. Morse, H. N.

Tliis part of tlic work deals with the principles for drawing charts representing the fields of motion in atmosphere and hydrosphere, and develops the practical methods required for passing from the single observations to these continuous representa- tions of the motion. From the observation, charts representing the horizontal cora- Donent of the motion are first derived. These charts being found, it is shown how other charts, representing the vertical component of the motion, can be derived by makmg a proper use of the hydrodynamic surface-condition and of the equation of 46 Chemistry and Physics continuity. The methods are also developed for deriving charts of acceleration from two charts representing the velocities observed at two successive epochs. The methods used in drawing these different kinds of charts may be considered as ex- amples of a special "graphical algebra" and "graphical differential and integral cal- culus," of which the fundamental principles are developed in two special chapters. This part is accompanied by 60 plates, 24 of which give a bathymetrical and hyp- sometrical map of the world on the scale 1 : 20,000,000, destined for use in meteoro- logical and hydrographical investigations.

These volumes contain the results of all magnetic observations made on land by the Department of Terrestrial Magnetism from the beginning of its observa- tional work in February 1905 to the end of 1913. Descriptions of the types of instruments used are given. The discussions of the general methods of the mag- netic and astronomical field work include, besides the general detail of selection and occupation of stations, specimens of field records, computations, and determinations of constants and corrections. However carefully constructed, various instruments give results differing by small, more or less constant, amounts, and in order to secure a standard of reference, extensive intercomparisons of instruments have been made at Vv^ashington, in the field, and at many magnetic observatories through- out the world; with these data it has been possible to reduce the magnetic results for the region covered in the publication to magnetic standards within an error in general on the order of the error of observation. In Volume I intercomparisons of the provisional magnetic standards adopted with standards of 12 observatories in the northern hemisphere and 4 in the southern hemisphere, are given, as also the indirect results of observations by other organizations at seven additional magnetic observatories in the northern hemisphere ; these show that the provisional standards adopted are very close to international standards, at least so far as all practical requirements of a general magnetic survey of the Earth are concerned. The corrections to these standards for the various instruments used are given in detail. The results are summarized as follows: Africa, 386 stations; Asia, 308 stations; Australasia, 10 stations; Europe, 36 stations; North America, 328 stations; South America, 111 stations; Islands of the Atlantic Ocean, 68 stations; Islands of the Pacific Ocean, 51 stations. The table of results contains for each station the geographical latitude, longitude, date of observation, observed values of magnetic declination, inclination, and horizontal intensity, the local mean times to the nearest one-tenth hour for each element, the instruments used, and the observer. The volume also contains descriptions of stations ar- ranged under the same geographical divisions adopted in the table of results. Volume II presents the results of all magnetic observations made on land by the Department from January 1911 to the end of 1913, and reports on some of the special researches and equipment. It describes new magnetic instruments of light and portable types, designed, constructed, and used for the field operations of the Department subsequent to the work reported in the first volume, including a combined magnetometer and dip circle and a combined magnetometer and earth inductor. The results of the extensive intercomparisons of instruments at Wash- ington and in all parts of the world are given in detail for each instrument. The stations at which the magnetic observations were made between 1911-1913 may be summarized as follows: Africa, 202; Asia, 83; Australasia, 284; Europe, 38; North America, 48; South America, 247; Islands of the Atlantic Ocean, 16; Islands of the Indian Ocean, 14; Islands of the Pacific Ocean, 16; Antarctic Regions, 30.

For the Galilee ocean work there are 443 tabular entries and for the Carnegie about 2,750, a total for the two_ vessels of about 3,200. After a general introduction and a brief account ot previous ocean magnetic surveys, the magnetic work of each vessel is treated separately. The construction of the Carnegie in 1909 is described and illustrated A special feature of the Carnegie work is the full account of the instruments devised by various members of the Department of Terrestrial Magnetism, and constructed m the Department's instrument shop, including descriptions and illus- trations of the manne collimating-compass for magnetic declination; the sea deflector for horizontal intensity and declination; the sea dip-circle for inclination and total intensity ; the marine earth-inductor for inclination, and a reversible gimbal stand. Ihe descriptions also give the scheme or method of observation with each instrument. The_ section on geographic position at sea is given special treatment under the Carnegte work, and specimens of observations and computations are added A brief account is given also of special investigations. A general statement, accom- pamed by diagrams, is made regarding the extent and character of the corrections which the existing magnetic charts require in order to make them conform to the observations on the Galilee and the Carnegie. Under extracts from the com- mander s field reports, are found, among other matters, notes on the occurrence of thunder at sea as observed on the Carnegie's cruise, 1915-16, and an account of the Carnegie s sub-Antarctic voyage of 1915-16. The special report by L. A. Bauer and W. F. G. Swann deals with the ''Results ot the atmosphenc-electnc observations made aboard the Galilee (1907-08) and the Carnegve (1909-16)." The introduction, by L. A. Bauer, summarizes the con- siderations determining the extent of the program of scientific work possible aboard such vessels as the Carnegie and Galilee. Next is given a compilation of the main atmospheric-electric results obtained at sea by the Department since 1907, as based on the field reports. A greatly increased program of atmospheric-electric work was undertaken on the Carnegie's fourth cruise (1915-16), and the paper contains a full account and discussion by W. F. G.

The conclu- sions reached are that the tides of the lithosphere, hydrosphere, and atmosphere at present are not sensibly changing the rate of the earth's rotation, and that the geological evidences indicate that during geological history the rate of rotation of the earth and its shape have been approximately as they are at present Professor Slichter gives, in tabular form, the polar and equatorial radii, the ellip- ticity, the polar and equatorial attractions, the latitude of mean radius, the equatorial contraction, and the meridional elongation for various rates of rotation The rate of change of rotation of the earth from the rate of degradation of energy in the ocean tides is computed by Professor MacMillan. The result reached after making liberal assumptions as to the magnitudes of the tides, is that they lengthen the day one second in 500,000 years. The first paper of Professor Moulton starts with the present earth-moon system and, by considering particularly the relations of energy and moment of momentum, traces the members of the system back to their closest possible proximity It is tound that at their closest possible approach their surfaces were more than 4 000 miles apart, and it is inferred that the moon did not originate by fission from 'the earth From a consideration of the secular acceleration of the moon's motion it is tound that the day is now changing at the rate of one second in 13,000,000 years Professor Moulton's second paper starts with the original united hypothetical earth-moon mass and considers the question of its fission. It is found that the mass could not suffer fission under contraction until its density became many times that at present. This paper, together with his preceding paper, leads to the conclu- sion that the moon has not originated by fission from the earth. Professor Chamberlin, in his second paper, considers the bearing of molecular activity on mass fission, and concludes that it keeps the equilibrium from becoming disturbed to such an extent that the separation of large masses is possible. Professor Lunn s work is mainly a quantitative study of that portion of the earth s mternal energy which may have been derived from the mechanical energy of a system of planetesimals. The computations are made for the Laplacian law ox density, and then the mfluences of certain secondary hypotheses are considered 51 52 Geology Professor Stieglitz makes a study of the conditions for precipitation and deposi tion of calcium sulphate, calcium carbonate, and calcium bicarbonate in the presenc of atmospheric carbon dioxide.

The fault where the earthquake originated is a part of a larger physiographic feature known as the San y-Vndreas rift. This rift and the geology of the coast system of mountains are carefully described in the first volume, which is miainly descriptive. Then follow detailed accounts of the displacements along all parts of the fault and descriptions of the effect and intensity of the shock in all parts of California and the neighboring States, where it was felt. All the phenomena observed are described, including the visible undulations of the ground, the formation of cracks, fissures, landslides, etc. The permanent displacements of the ground, as determined by geodetic measurements, are given, and the positions of certain monuments erected for the purpose of determining future sHps on the fault are recorded. The second volume, on the mechanics of the earthquake, contains a theoretical discussion of the phenomena described in the first volume. It traces the forces required to cause the rupture at the fault to drags applied from below, and points out that the rupture v^^as necessarily preceded by a relative displacement of regions on opposite sides of the fault, which suggests a method of anticipating certain earthquakes. The records obtained by seismographs in all parts of the world are given and discussed. A very complete mathematical theory of seismographs is given. No. 57. AVashington, H.

Volume I, Part I, contains observations relating to the geology of northeastern, northern, and central China (Shan-tung, Chi-li, Shan-si, and Shen-si). The treat- ment is primarily by districts, and under each district the terranes observed are described in order from older to younger. The nature and succession of strata, the fossils, and the structure of each terrane are discussed. The terranes observed may be enumerated as follows: Pre-Cambrian, Cambrian, Ordovician, Devono-Silurian (in Central China only), Carboniferous, Permian (?), Jurassic, and Quaternary. The principal contributions to knowledge relate to the Pre-Cambrian, the strati- graphy and fossils of the Cambrian and the history of the Quaternary. The last named comprises an analysis of the mountain forms in terms of uplift and erosion and a discussion of the loess. A unique feature is the account of an early Cambrian tilhte or glacial till, which underlies the Cambrian limestone of the Yang-tzi valley. The volume is profusely illustrated with photographs of the scenery of the mountain districts of Chi-li, Shan-si (the land of the loess), and Shen-si. The atlas contains 2 route maps, 20 topographic maps, and 20 identical geologic maps. The topographic maps represent the features along and adjacent to the route on a scale of 1 : 125000, with 100-foot contours. They are based on plane-table sur- veys and the forms of the land were sketched expressively in contours on the spot. Vol. I, Part H, includes three special reports which are subsidiary to the general treatment of the geological observations in Part I of the same volume. The first and largest section contains a description of the varieties of igneous metamorphic, and sedimentary rocks collected by the expedition in China. All of these specimens come from northern China, the majority of them being from Shan-tung, western Chi-li, eastern Shan-si, and southern Shen-si. The collection comprises typical representatives of the geological systems from Archean to Mesozoic. Of special importance are the description and interpretation of the varied oolitic and conglomeratic limestones found in the Cambrian terrane. The second section, dealing with zoological observations, includes an annotated hst of the amphibians, reptiles, and birds observed. About 130 species of birds are noted and of these 6 of the least known are illustrated by beautiful colored plates. Tj- u ^f^^^^^^^o" contains a syllabary of Chinese sounds, prepared by Professor Hirth, Ox Columbia University. The orthography recommended by the author 54 Geology compared in tabular arrangement with that of Williams and Wade, and all arc referred to the corresponding Chinese ideographs. Volume II treats of the same material as Volume I, but from the standpoint of systematic continental history. Repetition has been avoided so far as is consistent with the general subject. The subject-matter of this volume is classified primarily according to geologic eras of periods, and secondarily by broad areas, of which China proper is the central region. Each chapter treats of the geographic condition of southeastern Asia during a particular age, and the successive chapters trace the sequence of changes from age to age. Only the great events of continental history are distinguishable on the basis of existing knowledge, but they suffice to show that the present continent is an aggregation of land masses which, from time to time, have been forced into union with one another. This study of A<;ia has been carried on with comparative studies of North Am.erica and Europe, and has led to theoreti- cal vievv's regarding continental structure and development which have a broad application. They are briefly stated in a closing chapter. Volume III contains the description and illustration of the Paleozoic fossils col- lected by the expedition, of which the greater portion are Cambrian in age. The section devoted to the Cambrian, written by Dr. Walcott, includes the description and correlation of fossils collected by Prof. J. P. Iddings on Tschang-hsing-tau Island, Manchuria, and treats of the development of our knowledge concerning the geology and paleontology of the Cambrian formations of China. Each of the lo- calities is described in detail, with lists of included species and notes indicating their position in the general lists of species accompanying the discussion of the strati- graphy in Volum.e I ; the vertical and cross sections given in that volume are re- drawn, showing the locality numbers in their proper positions ; and the faunal hori- zons are correlated with each other and, so far as possible, with those of other countries. The volume also contains an important report by Prof. Stuart Weller on the Ordovician fossils collected in Eastern Asia in 1903-4, accompanied by two plates. These fossils include two collections, one from the province of Shan-tung and the other from the extreme eastern portion of the province of Ssi-ch'uan. Dr. George H. Girty has contributed to the volume a report on Upper Paleozoic fossils collected in China 1903-4, together with three plates. The specimens were obtained from localities quite widely separated and Dr. Girty's discussion of the col- lections is a valuable contribution to the geologic history of the region. No. 192.

No. 145. Case, E. C. A Revision of the Cotylosauria of North America. Quarto, 122 pages, 14 plates, 52 text figures. Published 1911. Price $3.00. This monograph, which is the second in the series dealing with the vertebrate fauna of the Permian or Permo-Carboniferous period in North America, gives a revision and morphological description of the group of primitive reptiles called Co- tylosauria. The same general plan is followed in this work as in the previous vol- ume on the Pelycosauria. The types are redescribed and the original descriptions quoted. Much new material is also described and a scheme of classification is pro- posed which reconciles all the facts now available. Several types which have been found to be indeterminable are so listed. The location and museum number of each type and characteristic specimen are given. A morphological description of each form follows the systematic portion with a discussion of probable relationships and habits. The bibliography includes all papers referred to in the text and all v/hich have been published since the appearance of Hay's Bibliography and Catalogue. No. 146. Case, E. C. A Revision of the Amphibia and Pisces of the Permian of North America. Quarto, 184 pages, 32 plates, 56 text figures. Pub- lished 1911. Price $4.00. This is the third monograph of the series on the vertebrate life of the Permian or Permo-Carboniferous period in North America. The method of treatment is the same as in the two previous monographs. A full systematic revision is given for both the amphibians and fishes, followed by a morphological description of each form. The location and museum number of each type and characteristic specimen are recorded. The bibliography is complete, in connection with Hay's "Catalogue and Bibliography of the Vertebrata of North America.'' The portion upon the fishes is the independent work of Dr. Hussakof, except the part included in the history of work upon the amphibians and fishes. A short article by Dr. E. H. Sellards describes two new cockroaches from the beds in Texas. No. 181. Case, E. C, S. W. Williston, and M. G. Mehl. The Permo-Carbonif- erous Vertebrates from New Mexico. Quarto, v-{-81 pages, 1 plate, 51 figures. Published 1913. Price $2.00. This is a supplementary volume to those published by E. C. Case on the Permo- Carboniferous vertebrates of North America. It contains an account of the ex- ploration of the Permo-Carboniferous beds of El Cobre Canyon, near Abiquiu, and those on the Arroyo de Agua, both in Rio Arriba County, New Mexico. Fos- sils of this age were first discovered in New Mexico by James Baldwin over thirty years ago, and specimens found their way into the hands of both Cope and Marsh, who described imperfect material. The result of this exploration was the dis- covery of a large quantity of new material, including some exceptionally perfect specimens. The monograph contains descriptions of new material, corrections of synonymy and of errors of interpretation, and references to all material described elsewhere. The two senior authors collaborated in order to avoid all possible errors and future discussion and are jointly responsible for all statements made by them. Dr. Mehl's part consists in the description of a single specimen. 56 Paleontology 57 No. 207. Case, E, C. The Permo-Carhoniferous Red Beds of North America and Their Vertebrate Fauna. Quarto, 176 pages, 24 plates, 50 text figures. Published 1915. Price $4.00. This is the fifth monograph of the series dealing with the Permian Vertebrates of the Permo-Carboniferous of North America. The first four deal with the taxonomy and the morphology of the different groups of vertebrates. The present describes: (1) The stratigraphy of the different beds in which the fossils occur; the conditions under which the beds were deposited; the climatology of the time interpreted from the deposits; all other recognized inorganic factors constituting the inorganic environment of the fauna. (2) The habits and inter-relations of the animals as interpreted from their structure; the food habits as interpreted from the teeth and other parts ; the possible food supply as a check on the assumed food habits. (3) The appearance of the forms, so far as known, with restorations of the better-known species. (4) The origin, development, and extinction, or disap- pearance,^ of the fauna. (5) The surface of North America in Permo-Carbon- iferous time; the possible land connections of the continent with other continents in reference to the possible migrations of the fauna. A synoptic table gives the geographical and geological distribution of the various forms and the author's idea of the proper classification. The whole monograph is a summary of our knowl- edge of the fauna and an attempt to study the evolution of the group from its inception to its extinction or final disappearance from the continent, in the light of all recognized controlling factors, organic and inorganic. The relations of the fauna to that of other continents is not treated in detail as it is planned to consider this phase of the matter in a continuation of the work. No. 75. Hay, Oliver P. The Fossil Turtles of North America. Quarto, iv-f 568 pages, 113 plates, 704 text figures. Published 1908. Price $9.00. This work has for its purpose the careful description of all the species of fossil turtles of North America that were known to exist at the time of publication. In all 266 species are described and, with few exceptions, figures are given of all of these. Of the 266 species 76 are regarded as hitherto undescribed. The classifica- tion of the order is discussed and the families and genera are carefully defined. Before entering on the consideration of the fossil forms the osteology of most of the^ living families is elucidated. The modifications undergone by the turtles since their earliest appearance are discussed, as well as the derivation of the order and its various families. There is a chapter on the geographical distribution of the living turtles, illustrated by 8 maps. Two tables present the geological distribution of the North American extinct species. This work is of interest to all students of these reptiles, as many of the genera here described still exist. No. 34. WiELAND, G. R. American Fossil Cycads. Quarto. Vol. I. Structure, viii+296 pages, 51 plates, 141 text figures. Pub- lished 1906. Price $6.25 Vol. II. Taxonomy, vii+277 pages. 58 plates, 97 text figures. Published 1916. Price $6.25. In volume I a record is made of the discoveries and collections of silicified cycads. Some of the more important finds noted were made by the author. These include the most remarkable of the branched forms. The various conditions of fossilization and methods of treatment, including the cutting of large thin sections, are taken up. The foliage of the Cycadeoids is determined from the young crowns of partially emergent fronds and compared with that of the existing cycads, some ncAv facts about the latter being brought out. The ovulate fructification 'is de- scribed in much detail, and the discovery of the bisporangiate flower buds is set forth on the basis of completely illustrated serial sections. The subject of young fructifications is dealt with in preliminary form. There is thus given a redintegra- tion of the long problematic Cycadeoid type. This part of the work affords a key to the study of many hitherto scantily known fossil casts and imprints of Cyca- daceous affinity. The closing chapters are devoted to a thoroughly illustrated com- parative study of the habitus and structure of the existing cycads and to a new 58 Paleontology theory of angiosperm descent from hypothetic types little remote from the early Mesozoic Cycadeoids. In volume II the structure of the Cycadeoids is taken up from the viewpoint of classification and nomenclature. Trunk structure is further considered on the basis of large poHshed transverse and longitudinal, and also thin sections. Notes are given on nearly all the more important American species, and the necessary comparisons with European forms are drawn. The aim is to give in clear and usable form the present status of Cycadeoid study. Incidentally many new details of both structural and general biologic interest are illustrated. In particular the remarkable monocarpic species Cycadeoidea dartoni is described. As in volume 1 extended comparison with existing cycads was made, so in volume II a well-illus- trated account of the related Mesozoic Cycadophytan stem, leaf, and fruit im- prints, and casts is appended. This in large part rests on the author's own dis- coveries in the Liassic of Mexico. A fuller account of the seeds is given, and new theories of seed and floral constitution are discussed. The descent of the angio- sperms is further considered. The two volumes therefore constitute a treatise on the Cycadeoids setting forth all the main features of the group thus far discovered. Both volumes are profusely illustrated and contain the necessary bibliographies. No. 238. MooDiE, Roy L. The Coal Measures Amphibia of North America. Quarto, x+222 pages, 26 plates, 43 text figures. Published 1916. Price $5.50. A complete account of the anatomy, distribution, classification, and relation- ships of the oldest known land vertebrates of North America is given so far as may be determined from the material which has been discovered. It is accom- panied by a bibliography of 645 titles, which are citations to all the studies made to^ December 1915, on the fossil Amphibia of the world. Especial emphasis is laid on the anatomical facts. Plates and text figures show the osteology, the lateral-line system, the dermal covering, the alimentary canal, and such other features as are possible of ascertainment from the fragmentary material. The history of the classification of the fossil Amphibia is given, together with an account of the discovery of the land vertebrates in the Coal Measures of North America. Dis- cussions of the manner of occurrence and the geological and geographical dis- tribution are accompanied by maps and photographs. A large share of the volume is devoted to careful description and classification of the 90 species which are now known to occur in the Coal Measures of North America, with figures, recon- structions, location of type material, synonymy, and references to the original descriptions.

The object of the exploration was to search for evidence for or against the Central Asiatic origin of early cultures, with especial reference to the hypothesis of a so-called Asiatic Aryan home. The volume of the Reconnaissance Expedition of 1903 contains the results of the separate expeditions of Prof. W. M. Davis, of Harvard University; of Mr. Ellsworth Huntington, and of Professor Pumpelly and Mr. R. W. Pumpelly. These results are chiefly: 1. The corroboration and extension of the evidence of an extensive Glacial and post-Glacial inland sea. 2. The independent determination of at least three Glacial and two inter-Glacial phases of the Glacial Period in the Tien Shan and on the Pamir. 3. The observation of a vast number of ruined sites of all ages, some of which were evidently of very remote age. The two volumes of 1904 treat of the archeological and physiographic results of the Second Expedition, with especial reference to the excavations at Anau and incidentally at Merv.

In the expedition of 1904 two sites on the Oasis of Anau were excavated, expos- ing four successive civilizations— Anau I, H, HI, IV, extending with breaks from 8000 B. C. to the beginning of our era, and aggregating over 130 feet of culture strata and a later city of the period of known history. The archeologist, Dr. Hubert Schmidt, of the Royal Museum fiir Volkerkunde of Berlin, describes the excavations and gives a critical description of the successive potteries and other finds. Prof. J. Ulrich Duerst, of the University of Berne, gives an extended com- parative anatomical study of the abundant animal remains, collected foot by foot from the lowest culture strata upward, of the two oldest civilizations. In these he finds the beginning of domestication and the differentiation of breeds and origin of some prehistoric European breeds. He also contributes a chapter on the desert horse of Anau in its relation to the varieties of domestic horses. In the opening chapters of Volume 1 (1904) Professor Pumpelly, after tracing the evolution of the environment that conditioned the prehistoric civilizations of .^9 60 Archeology Anau, reviews the characteristics of the civilizations and analyzes the results of his own and his collaborators' investigations. By physiographic methods there were obtained, through shafts in the oasis formation, a determination of the rate of alluvial growth relatively to that of the accumulation of the debris of civilization and evidence of three climatic cycles, paralleling the cultures, as well as their rela- tion to the rise and fall of these. The rate of accumulation of debris of civilization is found subject to a fixed law, and the stratigraphic rate is converted into a time scale v/hich is confirmed by the author's study of datable Eg)^ptian village mounds. Thus, and partly from internal evidence, is obtained the dating of the beginning of the cultures Anau I, II, III, IV (8000, 6000, 5000, 4000 B. C.) and 3000 to 4000 years as the duration of a climatic cycle. The civilizations Anau I, II were wholly Central Asian ; the people isolated from Europe and Africa, at least since an inter- Glacial period, by the inland sea of the Glacial epoch, were forced by increasing aridity on to the oases and to the evolution of agriculture. The dolichocephalic founders of Anau I and II were by long inheritance town-building cultivators of wheat and barley who later began the domestication and breeding of animals — the criteria of civilization. Toward the end of Anau III (5000 to 3000 B. C.) appears external (Chaldean) influence and culture. Anau I and II had slight knowledge of copper. Anau III covers the developed copper age, but ends before the use of bronze. There was a long gap between copper culture (III) and iron (IV). The agricultural preceded the nomadic shepherd stage. The arid extremes caused the great migrations. The climatic reaction following the Glacial period began the evolution of organ- ized civilization. Domestic animals and elements of agriculture of dolichocephalic Anau-li were brought to Europe in the late stone age by brachycephalic Asiatic immigrants. The relation of Anau cultures I and II to early Babylonia and Susa are discussed No. 53. MuLLER, W. Max. Egyptological Researches. Vol. 1. Results of a Journey in 1904. Quarto, 62 pages, 106 plates.

Volume 1 records the results of an expedition by the author in 1904, having as its object a study of the monuments recording the relations of ancient Egypt to foreign countries, especially to Asia and Europe — monuments which are mostly direct contributions to Biblical studies and in many ways elucidate the history of the whole world. Professor Miiller sought especially to secure final, or at least better, copies of the most important "known" texts rather than to obtain "new" material. Volume 2 is a continuation of the above and records the author's researches in 1906. No. 100. Ward, William Hayes. The Seal Cylinders of Western Asia. Quarto, xxix+428 pages, 1,500 text figures. Published 1910. Price $7.50. These seal cylinders were of the size of a large or small spool, purely cylindrical or v/ith the surface concave and in the latest Persian period convex and barrel-shaped. In the earliest period they were made of the central hard core of a conch shell from the Persian Gulf; afterwards of serpentine or lapis-lazuli ; then hard stones, quartz crystal, chalcedony, or carnelian. Every owner of property had to have one of the cylinders. The engravings on them were usually figures of the gods worshiped by the owners, or scenes of agriculture, war, or the chase. Later the owner's name would be added in cuneiform characters, with the name of his father and that of his favorite god. This work opens with an introduction describing the materials, the tools, the uses of the cylinders, and the principles of classification, and it closes with a discussion of religions and sacrifices, lists with figures of the gods and their sym- bols, and a conclusion as to the source of the earliest culture, which seems to have been in Elam, just east of Babylonia, on the Persian Gulf. The main body of the Archeology 61 work is devoted to the study of these seals as classified by nationality, period, and subject. Almost every page has several illustrations, so that the student of history, civilization, and art has here a body of material and conclusions not hitherto acces- sible to scholars. The present volume consists of about 450 quarto pages with over 1,500 drawings, and may be described as an investigation of the earliest art of Babylonia and its later ramifications, showing the sources of that stream of culture which finally over- flowed in Greek art and civilization. From that period of perhaps 4000 B. C, long before the use of iron, if not before that of bronze, the course of art and culture and religion is followed as it spreads over Persia on the east and as far as the Mediterranean Sea and Cyprus on the west, including Assyria, the Hittite Empire of Asia Minor, Syria, and Phoenicia. Thus the investigation reaches down to about 600 B. C, when the seal cylinder gave way to seals of other sorts, owing to the growing disuse of clay tablets for writing and the substitution of the simpler cone seal and scaraboid in place of the cylinder. No. 108. Van Deaian, Esther B. The Atrium Vestce. Octavo, xii-[-47 pages, 17 plates. Published 1909. Price $1.50. This is a careful study of one of the many interesting problems which arise in the study of Roman topography and Roman architecture. The magnificent House of the Vestals was not the work of one period, but was enlarged" and beautified during successive epochs, the later builders doing their work in such a way as to fit It, as far as possible, into that of their predecessors, thus producing the impression of a uniform structure. In this monograph the House of the Vestals is considered not as an isolated problem, but in connection with a thorou^rh study of Roman brick- work, and the author has reconstructed the history of the building for the first and second centuries A.

The Maya Inscriptions. The Inscriptions of Co pan, Honduras. Quarto, 34 plates. In press. This volume deals with the hieroglyphic inscriptions of the ancient Maya civiliza- tion of southern Mexico and northern Central America, and is especially devoted to a consideration of the inscriptions of Copan, Honduras, one of the largest and oldest centers of the Old Empire. This city flourished during the first five cen- turies of the Christian Era and is particularly noteworthy for the large number of its hieroglyphic monuments. The texts are presented upon a variety of media: stelas, altars, door-jambs, fagades, steps, and stairv/ays. They vary in length from 2 glyphs to over 2,000. In fact the longest inscription in the Maya writing is found here— the Hieroglyphic Stairway on the western slope of Mound 26, which contains upwards of 2,500 glyphs. Of the 81 texts under observation, which include all nov/ known, 22 were found to belong to The Archaic Period {i. e., from the earliest times down to 9 . 10 . 0 . 0 . 0, approximately to 360 A.D.) ; 17 to The Middle Period {i. e., from 9 . 10 . 0 . 0 . 0 to 9 . 15 . 0 . 0 . 0, approximately 360 to 460 A.D.) ; and 42 to The Great Period {i.e., from 9 . IS . 0 . 0 . 0 to 10 . 2 . 0 . 0 . 0, approximately 460 to 600 A.D.). There are many drawings and photographs of heretofore un- known or undescribed inscriptions, and these include a large amount of "new material" here made accessible to students of the Maya hieroglyphic writing for the first time. 62 Archeology The work closes with a number of appendices, including lists of the monuments upon which the investigation was based, arranged according to their chronological sequence; lists of all known contemporaneous monuments from other sites; corre- lation tables; distribution maps and diagrams and a complete bibliography of the site. In short this monograph presents an exhaustive study of the Copan inscrip- tions based upon a first hand examination of the originals.

Douglass, and Charles J. Kullmer. The Climatic Factor, as illustrated in Arid America. Quarto, 341 pages, 12 plates, 2 maps! 90 figures. Published 1914. Price $5.50. This study of changes of climate is a continuation of the work described in the author s papers in Nos. 26 and 73. It deals mainly with the relation of climate to geological, botanical, and archeological phenomena, but contains also a considerable amount of geographical description. The book begins with a discussion of the present climate of Arizona and New Mexico, and its effect upon the earth's surface and upon vegetation. Because of the aridity and scanty vegetation, deposits of alluvium are abundant and many are terraced. A consideration of whether these terraces are of climatic or tectonic origin leads to the conclusion that they are climatic, and that they indicate climatic pulsations during the period of human occupation. Numerous ruins, here and in Mexico, Yucatan, and Guatemala, point to the same conclusion and suggest the existence of at least three moist periods separated by times of aridity. An independent investigation of the same problem, based on the method of Prof A. E. Douglass, shows that the amount of rainfall may be determined from the thickness of rings of growth in trees. From measurements of 450 Sequoias in California a curve has been plotted showing the approximate pulsations of rainfall m California for 3,000 years. Comparison with meteorological records suggests that the pulsations consist of an alternate weakening and strengthening of atmos- pheric circulation, whereby climatic zones are moved first poleward, then equatorward. This conclusion leads to an attempt to determine the cause of changes of cli- mate, including not only recent changes, but those of geological times, which are discussed by Professor Schuchert, who lays special emphasis upon the im- portance of broad crustal deformation. Such deformation, however, can scarcely account for glacial and inter-glacial epochs, and much less for the pulsations in- dicated by the California trees. Only the solar hypothesis seems adequate. This conclusion is tested by investigating the possibility of a connection between varia- tions m sun spots and changes in the growth of trees. Such a connection seems to exist,^ and various phenomena suggest that apparent discrepancies are in reality results that would naturally be expected. Chapters 2, 4, 5, 6, and 10 deal with the geological problem of the effect of aridity upon surface forms and upon subaerial deposits. The problem of the tec- tonic versus climatic origin of alluvial terraces in dry mountain regions is treated at length. Chapters 19, 20, and 21 discuss theories of climatic changes, special em- phasis being given to the solar hypothesis as the cause of changes of the masrni- tude of glacial epochs or less, and to crustal deformation as the cause of greater changes, such as glacial periods. Inasmuch as botanical evidence is largely used in elucidating the climate of the past, Chapter 2 describes the arboreal desert of the southwestern United States. Chapters 11 to 14 discuss the relation of the thickness of rings of growth to chmatic conditions, not merely in the case of the Sequoia of California, but among trees from all parts of the country. The evidence presented in Chapters 15, 16, and 17 suggests that in equatorial regions plant formations may be displaced by climatic changes with a degree of rapidity which must cause the process of natural selection to act with greater speed than is commonly supposed. The climate of the past stands in vital relation not only to geology and botany, but to men. Hence it is necessary to consider fully the ruins of the Southwest and the conditions under which the people lived. This is done in Chapters 6 to 10. The ruins and civilization of the Mayas in Yucatan and Guatemala are also im- portant lines of evidence, and in Chapters 15 to 18 the theory is advanced that when the Mayas were in their prime the lowlands of this region were decidedly drier than now. 63 HISTORY.

This paper endeavors by means of published correspondence, especially the Drop- more Papers, to answer the important question how far the foreign policy of Eng- land during the prime ministry of William Pitt the younger, and especially during the period when his cousin Lord Grenville was Secretary of State for Foreign .Af- fairs, was devised and controlled by Pitt, and how far his management of foreign affairs during that critical period was influenced by Grenville.

The first historical enterprise of the Carnegie Institution was the making of an inventory, more largely from an historical than from an administrative point of view, of the governmental archives in Washington. The need of such an inventory was peculiarly pressing on account of the want of concentration of archive material in our national capital. Far from having effected such concentration as has been brought about by the English government in its Public Record Office, our practice has been, except in the case of the War Department, to leave the custody and ar- rangement of the papers of each subdivision of a department to its administrative chief, so that the archives of the government consist of at least a hundred separate deposits, classified and managed in different v/ays and in different places. Messrs Van Tyne and Lejand brought out in 1904 a volume of 215 pages, indicated under No. 14 above. This volume is now out of print. A new edition being requisite, Mr. Leland spent a year in revision and amplification, this work resulting in Publication No. 92, which describes the historical papers accumulated by each office of the gov- ernment, including the two Houses of Congress and the Library of Congress.*' No. 22.

Inventory of Unpublished Material for American Re- ligious History in Protestant Church Archives and Other Repositories Octavo, vii-f254 pages. Published 1911. Price $1.50. American religious history, if dealt with not in a denominational spirit but on broad lines, is quite as important a part of the historian's concern as any other aspect of the social history of the United States. Of the unprinted material for it, how- ever, a large part has escaped the knowledge of workers because of being kept in 65 66 History denominational or local repositories which have not had the same means of making their treasures widely known as are possessed by governmental establishments and public libraries. Therefore Mr. Allison was commissioned to make a personal ex- amination of the manuscript materials for American religious history in the acces- sible archives of Protestant denominations, of their missionary societies, and in the libraries of their theological seminaries, colleges, and historical societies. The book lists, in alphabetical order by States and cities, the voluminous but scattered ma- terials thus found. An elaborate index brings the material conveniently together. No. 148. Parker, D. W. Calendar of Papers in Washington Archives relating to the Territories of the United States. Octavo, 476 pages. Published 1911. Price $3.00. Two-thirds of the States have been Territories. Therefore, the materials for their earlier history are in large degree to be found in one or another of the gov- ernmental archives in Washington. Much effort is expended by workers in these States in the endeavor to find materials of this class. The difficulties are made very great by the extraordinarily dispersed condition of the records of the government, which has not one archive, but at least a hundred; and the distribution of papers among them is often casual or arbitrary, and in all cases it is hard to follow. Mr. Parker, after spending many months in listing in a wide variety of governmental archives in Washington the papers, relating to the history of the several territories, more especially their constitutional, political, and administrative history, has brought the data together into a form classified first by territories, and chronologically under each territory. This mode of classification, together with a full index, makes avail- able a vast amount of material, most of which was hitherto entirely unknown to investigators. The number of items in the Calendar is nearly ten thousand. No. 172. Parker, D. W. Guide to the Materials for United States History in Canadian Archives. Octavo, 339 pages. Published 1913. Price $2.00. The archives of the Dominion of Canada in Ottawa are made up of two great masses of material. One is a great collection of transcripts from the English and French archives. Of these the Dominion Government published calendars, and Mr. Parker could therefore give them a summary treatment, the more so because the originals from which they are copied will be described in the Institution's books on the London and Paris archives. The other mass comprises what may be called indigenous Canadian materials, derived from the offices of the Governor-General, the Secretary of State, and the various ministries, and rich in materials for the history of the United States, especially in the period since 1791. Besides a careful descriptive list of these, Mr. Parker has included in the book similar accounts of the materials for United States history in the provincial archives of Nova Scotia at Halifax, in those of New Brunswick at Fredericton, and in those of the Province of Ontario at Toronto. Full accounts and lists of materials of similar bearing in the civil archives of the Province of Quebec and in the ecclesiastical archives of the archbishopric there, and briefer descriptions of the archives of Newfoundland, British Columbia, and other western provinces have been added by other hands.

Guide to the Manu- script Materials for the History of the United States to 1783, in the British Museum, in Minor London Archives, and in Libraries of Oxford and Cambridge. Octavo, xiv-[-499 pages. Published 1908. Price $2.00. The chief masses of material in London for the history of the United States are those in the Public Record Office. A volume relating to these, upon which Professor Andrews has expended a large amount of time and labor, would natu- rally have had precedence over this present work; but its publication has had to be deferred on account of the large amount of reclassification which the Public Record Office has resolved upon in respect to the Colonial Office papers and other portions of the whole. Accordingly the present volume, though naturally supple- mentary, has been brought out first in order. Professor Andrews has furnished an itemized list, with proper explanations and comments, of all those papers in the library of the British Museum which relate to the history before 1783 of the United States and all other British portions of North America. Thi'-> he has followed History 57 with an account of the materials in the Privy Council Office. Miss Davenport has furnished detailed statements of the materials for American history preserved in the archives of the House of Lords, in the library of the Archbishop of Canterbury at Lambeth, in that of the Bishop of London at Fulham, and in other archives, public and semi-public, civil and ecclesiastical, in London. Professor Andrews concludes the volume with an itemized list of the American papers in the Bodleian Library and in other hbraries of Oxford and Cambridge. The volume is minutely indexed. No. 90a.

Price $2.50. Vol. IL Departmental and Miscellaneous Papers, viii-f427 oasres Published 1914. Price $3.00. Of all archives in Europe the Public Record Office in London contains by far the greatest quantity of material for the history of the United States, and par- ticularly for the period before 1783. For many subjects in the history of the colo- nial and revolutionary periods, indeed, there is much more unprinted manuscript in that one repository than in America itself. Volume I, in its introduction, gives a history and description of the Public Kecord Office, its rules and regulations, and statements respecting such of its pub- lications as are useful to American inquirers. The contents of the archive are classihed in two grand divisions, the one that of State Papers, the other that of Departmental and Miscellaneous Records. Of these, it is the State Papers which arc treated in the present volume. After an historical introduction upon the Sec- retary of State and his duties and upon the State Papers Office, the various series of State Papers Foreign, State Papers Domestic, Home Office Papers, State Papers Miscellaneous, State Papers Colonial, and Colonial Office Papers are described with full presentation of details. These are most abundant in the section devoted to the Colonial Office Papers. The reclassification of the Colonial Office Papers has so completely made obsolete all previous descriptions that Professor Andrews's minute description of them in their present order or arrangement must be of the greatest utility to all students of American colonial history. Volume II presents a detailed description, volume by volume, of the divisions of the Public Record Office known as Departmental Records and Miscellaneous, 1 he Departmental Records comprise the papers of the Admiralty, the Audit Office (including the Declared Accounts), and the Lord Chamberlain's Department the Commissariat, the Custom House, the Treasury, and the War Office. The Mis- cellaneous section embraces the records of the High Court of Admiraltv, the Man- chester, Cornwallis, Shaftesbury, Rodney, and Chatham papers, and those of the modern Board of Trade. The divisions of the Public Record Office embraced in this volume have been much less used for purposes of American history than the Mate Papers ' described in Volume L The largest sections of the book are thos.- relatmg to the Treasury, the Admiralty, the War Office, and the High Court of Admiralty. Each of the two volumes has its own index. No. 90b. Paullin, C O., and F. L. Paxson. Guide to the Materials in London Archives for the History of the United States since 178^ Octavo xi+642 pages.

E. Fryer and Mr. David W. Parker. The volume furnishes a comple- ment to those of Professor Andrews, and of Professor Andrews and Miss Daven- port, by supplying similar guidance to materials for the later period The official permissions for search originally extended to 1837 for most departments, but were later extended to 1860. Thus the book contains descriptive lists, for 1783 to 1860 of all the materials for the history of the United States which are to be found in 'the sections at the Public Record Office known as Foreign Office Papers, Home Office Papers, Colonial Office Papers, War Office Papers, Admiralty Papers, and many minor subdivisions.

This book aims to assist those using No. 91 as well as other investigators of the history of the United States in its relation to Spain, by indicating all those docu- ments useful to their purposes, in Spanish archives, which can be examined without going or sending to Spain. It consists of two lists. The first indicates, in chrono- logical order and with proper references, all those documents of this sort which are already in print.

While presenting descriptive accounts of all the archives in Mexico examined by Professor Bolton, this volume is mainly occupied with lists of documentary ma- terials bearing on the history of the United States. The largest part of it is devoted to such lists for archives in the city of Mexico; but a large number of provincial archives were searched, especially in the cities of northern Mexico upon which the regions now called Texas, New Mexico, Arizona, and California at one time de- pended, either in a civil or in an ecclesiastical sense. To a large extent these searches have been pioneer worls laying open treasures of material hitherto un- explored. Many of the documents bear upon the history of the relations between Mexico and the United States, especially about the time of the Mexican War; others illustrate in countless ways the progress of exploration, Spanish colonization, mission work, Indian hostilities, and American settlement in the present southwest. In the city of Mexico, to whose archives the major portion of the book is devoted, the repositories most largely reported upon are the national collections in the Archivo General y Publico and the archives of the executive departments, especially the Sec- retaria f^e Relaciones, the Secretaria de Gobernacion, and the War Department. No. 83. Per^:z, Luis Marino. Guide to the Materials for American History in Cuban Archives. Octavo, x+142 pages. Published 1907. Price $0.75. The Cuban archives, in spite of the removal of large quantities of papers to Spain in 1888 and 1898. and of many losses due to political changes, embrace a large mass of valuable historical material. The fact that, under the old administrative system of Spain, Florida and Louisiana were under the jurisdiction of the captain-general of Cuba, brings it about that considerable masses of these papers have a direct relation to the history of the United States. Mr. Perez spent five months in the investigation of these papers. His book gives a general description of the Cuban archives, traces historically the development of the administrative system of Cuba, describes the principal archive material relating to the history of the United States, and furnishes an itemized list of the papers most important in this respect. No. 128. Fish, C. R. Guide to the Materials for American History in Roman and Other Italian Archives. Octavo, ix-f259 pages. Published 1911. Price $2.00. Nine-tenths of this book relates to archives in Rome. In that city the two col- lections most abounding in materials for American history, and described in the History 69 most detailed manner in this volume, are the archives of the Vatican and those of the Congregation of the Propaganda. The former embraces the correspondence of the papal secretaries of state with the nuncios of Spain, France, and other colo- nizing countries, and various correspondence with bishops and other ecclesiastics in America. Taken in connection with the archives of the Propaganda, or chief mis- sionary office, these archives not only display with great fulness the ecclesiastical and religious history of early America and of the Catholic portions of the United States, but also cast an extraordinary amount of light upon the civil history and administration, especially French and Spanish. Besides the Vatican archives, the volume embraces the manuscripts in the Vatican Library, in other ecclesiastical collections, and in public and private libraries in Rome. The archives of Naples, Venice, Turin, and Florence are likewise included. There is a full index. No. 150. Learned, M. D. Guide to the Materials relating to American History in the German State Archives. Octavo, vii+352 pages. Published 1912 Price $2.25. German materials touch the history of the United States in the ordinary manner of diplomatic relations, and also, and in a very interesting manner, in the particular episode of the Hessian and other auxiliary troops in the American War of Inde- pendence. But the leading relation between German history and that of the United States has lain in the field of the history of German emigration, which, beginning in the seventeenth century and continuing to the present time, has contributed no doubt not less than one-fifth to the population of the United States. Therefore Professor Learned's inspection of German archives, though ample and detailed in the case of diplomatic archives and of the Hessian and other military papers was far from being confined to these. On the contrary, he made an examination of all seventeen of the Prussian provincial state archives, of the eight provincial archives in Bavaria, and of the archives of the minor German states, making it his chief object to note volumes and papers which bore upon the history of the migration of German population to America. The volume is minutely indexed. No. 220. Faust, A. B. Guide to the Materials for American History in Swiss and Austrian Archives. Octavo, x+299 pages. Published 1916. Price $2.00. In Switzerland there is some material for American history in the archives of the Confederation at Bern, but still more in the archives of the cantons This is mainly because of the large emigration from the German-speaking cantons of bwitzerland to America in the eighteenth and nineteenth centuries.

Mr. Hill's book, the product of more than two years' labor in Seville on his part and that of clerical assistants, describes the contents of each of these legajos as fully as this can be done in the average space of half a page or a little more, and with such fullness of detail as to personal and geographical names as will enable investigators to find whatever material in this section of the archives relates to the particular subject of their inquiries. An itemized list of all the documents in 158 of the most important legajos is kept in manuscript in the office of the Department of Historical Research, which has also photographed a series of more than 2,000 of the chief documents. No. 239. Colder, Frank A. Guide to Materials for American History in Russian Archives. Octavo. In press. The Russian archives contain two sorts of materials relating to the history of the United States : one, papers relative to the diplomatic relations between the two countries from the American Revolution down to the present time; the other, papers relating to Russian explorations in the Northern Pacific, and the settlement and development of Russian America, now Alaska, down to its transfer to the United States in 1867. These materials are preserved in a large number of different archives at Moscow and Petrograd, those of dates subsequent to 1800 being in the latter capital, v/hile some of those of eighteenth-century dates are kept in Moscow. Mr. Colder devoted several nionths to the examination of all of those archives, and found a rich store of materials, v/hich he has described carefully and systematically. Most of the diplomatic papers at Petrograd are in the archives of the Ministry of Foreign Affairs, in which Mr. Colder was permitted to pursue his investigations dov/n to the year 1854 without restriction. In the other archives he was allowed to proceed to even later dates. The diplomatic papers will be especially useful to students of such episodes as the Russian mediation in 1813, the arbitration of 1822, the treaty of 1824, Russian action during our Civil War, the Alaskan negotiations of 1867, the Fur Seal Arbitration of 1893, and the boundary settlement of 1903. On the other hand, the book lists a large variety of correspondence, journals, log-books, manuscripts, maps, and charts relating to the explorations of Bering, to later explorations, and to the early history of Russian America.

This History of Domestic and Foreign Commerce of the United States, in two volumes, constitutes one division of the Contributions to American Economic History being prepared by the Department of Economics and Sociology of the Carnegie Institution of Washington. Volume I contains three parts dealing, re- spectively, with "American Commerce to 1789," "The Internal Commerce of the United States," and "The Foreign Trade of the United States Since 1789." Volume II also has three parts devoted, respectively, to "American Fisheries," "The Coast- wise Trade of the United States," and "Government Aid and Commercial Policy;" this volume also contains a bibliography topically classified. Part one of Volume I, with the exception of two chapters, was written by Emory R. Johnson, Professor of Transportation and Commerce at the University of Pennsylvania, while the remainder of the two volumes was written by Dr. T. W. Van Metre, Assistant Professor G. G. Huebner, and Dr. David S. Hanchett. Sev- eral collaborators made special studies that were used along with other material in writing the volumes. Professor Johnson has directed the preparation of the entire work and has edited the parts contributed by his associates. No adequate history either of the foreign or of the internal trade of the United States had previously been written. While there is a large literature upon com- mercial subjects to be found in government reports and other publications, these volumes are the first to cover systematically the entire field of the history of American commerce.

This volume contains a history of American manufactures from the settlement of Virginia to the Civil War. Its purpose is to picture and to explain the begin- nings of that growth which has made manufacturing one of the most important forms of natural production. The more important economic influences affecting general^ manufactures and specific industries are described and their relation to our industrial development is traced in detail. While the arrangement is loosely chrono- logical, the topical method of treatment prevails. There are very full references to the published and unpublished materials, and the book contains new statistical and bibliographical data of importance. No. 215c. History of Transportation in the United States before i860. Prepared by Caroline E. MacGill, under the supervision of Balthasar H. Meyer. Octavo. In press. The History of Transportation in the United States before 1860, prepared by Caroline E. MacGill and a staff of collaborators under the direction of Dr. B. H. Meyer, is the third book to be issued in the series of Contributions to American Economic History, published by the Carnegie Institution of Washington. This volume is based upon a series of monographic studies made by pupils of Professor Meyer and by other economists, who made free use of the extensive library of books on transportation given to the University of Wisconsin by the late Tames J. Hill. Transportation is the key to the economic progress of the United States. The great natural resources of the country could never have been developed without adequate means of bringing people to work them and of bringing the finished prod- 72 American Economic History 73 uct to the market. Transportation is also essential to the success of our political system. Without free communication between its different parts, this vast terri- tory could hardly have governed itself successfully under a free Constitution. The history of transportation is the story of the successful conquest of great natural obstacles. The early settlers had to follow, in most cases, the Indian trails, many of which had, in turn, been first traced by the buffalo. The trail was broadened into the wagon road, the wagon road was converted into the turn- pike, and the turnpike made possible the canal and the railroad. This volume stops at the Civil War, and, therefore, does not deal with the railroad problems of the present day, in the solution of which Dr. Meyer, as Chairman of the Interstate Commerce Commission, is now taking a responsible and onerous part. But it covers the romantic beginnings which are full of interest to the general reader, beside embodying many hitherto inaccessible data which are of great value for the Qnecialist. 74 American Economic History INDEXES TO STATE DOCUMENTS.

The index embraces reports of the boards of agriculture, charities and corrections, education, public works and public health, banking, insurance, railroad and tax commissions, bureaus of labor and vital statistics, climate and crop bulle- tins, geological surveys, fish, game, and forest commissions, auditors' and treas- urers' reports, immigration, sewerage and water-supply, roads, canals and river con- servancy, governors* messages, and reports of attorneys general. Particular care has been taken in reading the above-mentioned reports to note recommendations, sug- gestive comment, and especially the character of the tabulations. A check-list of the entire file of reports accompanies each subject. The indexed material is arranged chronologically under each subject. Thus the student is able to trace the historical development of each economic subject as it is reflected in the documents of an individual State. The work is published by States, a single volume to a State, and is designed to cover the period from the adoption of the Federal Constitution to the close of the year 1904.

The Folio American State Papers (Foreign Affairs), which ceased in 1828, have indexes, and an index to the annual Diplomatic Correspondence beginning in 1861 has been published by the State Department. The present publication indexes the documents of the intervening period, from 1828-1861. It affords reference to the entire published record of documents, papers, correspondence and, to a considerable extent, legislation and decisions upon international or diplomatic questions. In addition to the reports of Congress, the following series of documents have been indexed: the Senate Executive Journal, for diplomatic and consular appointments and treaty ratifications; the Opinions of the Attorneys General, for decisions on questions of international controversy; the Statutes-at-Large, for acts and resolu- tions relating to international affairs; and the Congressional Globe and its prede- cessors for speeches and correspondence. The text of the latter, it was found, does not always correspond with the text as printed in the House and Senate documents. LITERATURE. No. 74. SoMMER, H. OsKAR.

It represents the first attempt to produce a complete printed text of the whole of the Vulgate Cycle comprising* the early history of the Holy Grail; the prose-rendering of Robert de Borron's Merlin and the Book of Arthur ; the huge compilation of adventures known as the Book of Syr Lancelot of the Lake; the Quest of the Holy Grail; and the Death of Arthur. The text is a faithful reproduction of one of the six manuscripts known con- taining the entire Vulgate Cycle, viz, the Add. MS. 10292-10294 of the British Museum. It has been collated, supplemented, and corrected by help of other manu- scripts representing only certain sections of the cycle in the same library and in some special cases by the help of manuscripts in the Bibliotheque Nationale, of Paris. The lines are numbered and reference numbers to other manuscripts and printed editions are added throughout. Ample side-notes in English are supplied. In his Introduction Dr. Sommer briefly outlines the results of his studies on thf^ genesis of the Vulgate Cycle. His views differ in many essential points from those hitherto accepted as probable or correct. Volume I: Lestoire del Saint Graal, 296 pages. Volume II: Lestoire de Merlin, 466 pages.

Published 1912. Price $1.25. Pierre Du Ryer wrote at the time when the drama of modern France was first gaining national significance. The group of authors to which he belonged estab- lished the French classic drama as a distinct literary form, composed many tragi- comedies, both classic and romantic, originated for their country the comedy of manners, and did much to develop the technique of dramatic composition and repre- sentation. A thorough understanding of their achievement requires a careful study, not only of Corneille, the most important of these dramatists, but also of the lesser writers, who often showed the way to their illustrious contemporary. The present volume studies exhaustively the life and plays of Du Ryer, who, after Corneille, was in many ways the leading member of the group. Du Ryer's translations and lyric poems are treated in their relation to his life and dramatic work. The book contains an index, and is illustrated by vignettes and a plate reproduced from an early edition of Du Ryer's tragedy "Saul." No. 189. Osgood, Charles G. A Concordance to the Poems of Spenser. Quarto, xiii+997 pages, 1 plate. Published 1915. Price $20.00. This book is an alphabetical list of all the words in the English poems of Edmund Spenser. Under each word are quoted all the passages in which the word occurs, except that for a few very frequent and unimportant words only a selected list of quotations is given. The context of the word in each quotation is selected so as to show, as far as space allows, the meaning and use of the word. The whole work contains nearly 200,000 quotations. It is based upon the text of Richard Morris, revised and corrected by editions which have appeared since the concordance was begun. Spenser is usually ranked fourth among English poets, and his place in the history both of the English language and of English poetry is peculiarly important. The object of the concordance is not only to illuminate the poet's meaning and art in the use of words, but to afford aid to the historical study of the language and literature similar to that to be derived from concordances to the Bible, Shakespeare, Milton, Pope, Wordsworth, and other English poets. No. 202. Cooper, Lane. A Concordance to the Works of Horace. Octavo, x+593 pages. Published 1916. Price $7.00. This strictly analytical work records, in alphabetical order, every occurrence of every word in Horace, and all the variant readings included in two standard modern editions of the poet. Under each word is quoted every passage in which the word occurs, with a numerical reference to poem and line ; save that in the case of a few particles, no quotations, but numerical references alone are given. The basic text is that of Friedrich Vollmer (Leipsic, Teubner, 1912) ; his list of variants has been supplemented by the inclusion of a few readings noted in the edition of Wickham (Oxford, Clarendon Press, 1903-1904). The arranging of related grammatical forms under one heading has not been attempted; but homographs — for example, datives and ablatives ending in o — have been carefully separated. No effort has been spared to make the book typographically clear and easy to consult. The thought and language of Horace have exerted a profound and widespread influence upon subsequent poets, Enghsh as well as Continental. In common with other Latin authors, his works have in times past been indexed ; but of the previous verbal indexes still in print there is none that duly performs the functions of a concordance or adequately serves the purposes of the students of modern as well as ancient literature. Zangemeister's edition (now out of print) of Bentley's Horace contains an index which is virtually a concordance, but the typographical arrange- ment is so bad and the progress of studies in the text of Horace since 1869 has been so great, that, were his index more accessible, there would still be room for a new work. The present concordance was undertaken in view of difficulties actually experienced, with various indexes, in the comparison of English poets with Horace. No. 208. Broughton, L. N., M. R. Thayer, and others. A Concordance to the Poems of Keats. Quarto. In press. This work contains an alphabetical list of the words in the poems of John Keats. Under each word, except for a very small list of unimportant words, is Literature 77 quoted every metrical line in which the word occurs, approximately 65,000 quota- tions in all. The basic text is that of H. Buxton Forman, C. B. (Oxford Univer- sity Press). The recording was done from the issue of 1910; but has been care- fully collated with the issue of 1914, which contains five newly discovered poems. The page numbers given in the concordance correspond to those of the later issue, but for the convenience of those using the earlier text a table in the introduction carefully and completely records the relatively small number of changes in pagi- nation. The text is supplemented by the variant of La Belle Dame sans Merci from Lord Houghton's Life and Letters of Keats. PHILOLOGY, ETC. No. 169. Callaway, Morgan, Jr. The Infinitive in Anglo-Saxon. Octavo, xiii-j- 339 pages. Published 1913. Price $5.00. In this work Professor Callaway gives a detailed history of the Infinitive in, Anglo-Saxon and treats of some substitutes therefor. The study is based upon a statistical reading of the whole of Anglo-Saxon literature with the exception of the glosses and of a few out-of-prints ; moreover, in all of the more definitely known, translations, the Latin originals have been read. The statistics are given clearly and are complete except for the predicative infinitive with auxiliary verbs, the full tabulation of which seemed unnecessary. Fifteen chapters of interpretation are based upon this material. A long chapter is added on 'The Infinitive in the Other Germanic Languages," which of necessity rests upon the investigations of others, but which will, it is believed, be found something more than a summary. The bibliography makes no pretensions to exhaustiveness, but is fuller than any hitherto published in this field. It is thought that the monograph will appeal to students of Germanic syntax scarcely less than to students of English syntax, for the work IS written throughout from the comparative standpoint. No. 134. Churchill, William. The Polynesian Wanderings. Tracks of the Migration deduced from an Examination of the Proto-Samoan Con- tent of Efati and other Languages of Melanesia. Octavo, viii+516 pages, 2 plates. Published 1911. Price $3.50. Two theories of the origin of the brown Polynesian race of the Pacific are here discussed, the Semitic and the Malayan theories respectively. It has been essayed to dispose of these definitely by the methods of comparative philology. To that end the author has amassed all available data from all the Polynesian lan- guages and from 150 used in Melanesia and 50 Indonesian tongues; he has discussed their phonetic mutations and therefrom has pronounced against each of these theories. Dealing with the Polynesians as a pre-Malayan population of Indonesia, he shows that the race advanced upon the Pacific in two swarms separated by a wide interval of time. Confining his investigation to the earlier swarm, at or about the beginning of the present era, he outlines two streams of migration parted at the outset by the obstacle of New Guinea and not brought into association until their arrival in Nuclear Polynesia. As a contribution to the philology of the isolated tongues it is indicated that these studies set us at a point of examination but nar- rowly removed from the genesis of one of the languages of human speech. No. 154. Churchill, William. Beach-la-mar: The Jargon or Trade Speech of the Western Pacific. Octavo, 54 pages. Published 1911. Price $0.50. This work is directed toward two ends. The preservation of the vocabulary is expected to afford material for those students who may be attracted to the prosecu- tion of research upon jargons as underlying the artificial languages in general, a theme as yet untouched in philological examination. The discussion of the gram- mar of this crude means of communication has a value of its own as a preliminary step in the consideration of the grammar of isolating speech, a study essential to the establishment of the newer philology based upon the most primordial stage of the evolution of human speech. No. 174. Churchill, William. Easter Island, Rapanui Speech, and the Peopling of Southeast Polynesia. Octavo, 340 pages. Published 1912. Price $2.75. Herein have been assembled the word-lists of all former students of Easter Island, the French vocabulary compiled by Pere Hippolyte Roussel, the words recorded by Geiseler, Thomson, and Cook, together with the author's own collec- tions. To this material has been added the necessary philological apparatus where- with to make this the first dictionary of the speech of this remote outlier of the Polynesian race. Prefaced to the dictionary is a discussion of the various languages ©f southeastern Polynesia, namely, those of Tahiti, the Marquesas, the Paumotu, and 78 Philology, etc. 79 Mangareva. This material has been employed to dissociate the several streams of Polynesian migration which have moved eastward from Samoa under the helio- tropic impulse which has ever been active in this great movement of folk migration in these studies it has been possible to dissect out earlier and later migrations and to a satisfactory extent to translate into terms of geography the results of philo- logical comparison. No. 184. FiNLEY, J. P., and William Churchill. The Suhanu: Studies of a Sub- Vtsayan Mountain Folk of Mindanao. Octavo, ivH-236 pages 2 places Published 1913. Price $2.00. In Part I of this work Colonel John Park Finley, U. S. Army, has furnished a record of the present stage of this mountain tribe of Mindanao, a race hitherto practically untouched by even such culture as the Moros of the coast possess. Since St. Francis Xavier gave them up in despair they have remained in unmixed savagery until now they are being brought within the civilizing efforts of American endeavor. This record is as complete as could be obtained by ten years of admin- istrative contact with this shy and rude folk. In collating the linguistic material collected in the intervals of campaigns by the military author, Mr. Churchill hag established the ethnic position of the race as archetypal in reference to the more widely extended Visayan culture. This theme leads naturally to a careful discus- sion of the Malayo-Polynesian speech family and the employment of this important collection of new data to accomplish its demolition, thus clearing the way for a free study of the respective language units which hitherto have been obscured bv En untenable association. No. 244. Churchill, William. Sissano: Movements of Migration within and through Melanesia. Octavo, 181 pages, 17 charts. Published 1916 Price $2.00. Newly available material derived from the Sissano, a people on the Arop lagoons on the north coast of New Guinea, has been utilized in this work for the study of one of the more intricate problems of the track of Polynesia migration out of Indonesia. Objection has been raised against the suggestion that two migration tracks were discernible in reference to New Guinea as in part obstacle and in part conduit of folk movement. These tracks have been traced along the north coast of the island and along the south coast through Torres Strait. It has been sug- gested that the traces of Polynesian speech found in the Gulf of Papua havp reached that area by coastwise voyaging from the north coast to the southeast peninsula and thence westward. By the employment of the speech material from isissano tor the explication of the similar material found in the Torres Strait tract it is established that all the evidence at present available indicates the probability of the folk movement eastward from the Arafura Sea through Torres Strait inde"^ pendently of the movement along the north coast.

The Caddo tales presented in the above publication were collected during the years 1903-1905 and form part of a systematic investigation of the religious system and ceremonial organization of the tribes of the Caddoan stock. The Caddo smce 1859 have lived in western Oklahoma, between the Washita and Canadian rivers, where they have been closely associated with the Wichita. They retain practically nothing of their ancient culture. Their early home was in Louisiana, on the lower Red River. Later they migrated toward the Texas border, and still later to Brazos River in Texas. Like the Wichita, their early habitations were conical grass lodges, and they were agriculturists, hunting the buffalo only within comparatively recent times. No. 59. DoRSEY, George A.

The tales are grouped according to the Pawnee conception of tales : True Stories of the Heavenly Beings ; Tales of Ready-to-Give ; The Origin of Medicine Ceremonies or Power; Coyote Tales. A brief introduction relates the method of obtaining the material and all the tales are furnished with abstracts. Many of the tales contain ont or more songs. 8o EMBRYOLOGY. No. 191. Weed, Lewis H.

Data regarding the stages in the initial spread of this fluid were obtained by morphological studies and by a physiological method of replacement of the existent fluid. Two functional areas for the extraventricular passage of the em.bryonic ventricular fluid are described. The process of differentiation of the perimedullary mesenchyme into the_ three meninges of the adult is considered with regard especially for the circulation of the cerebro-spinal fluid through the subarachnoid spaces. Throughout this paper, the morphological changes in the development of the cerebro-spinal spaces have been related as far as possible to the physiological use of these channels. No. 226.
