 Having the largest and most complete stock of Mathematical, Engineering 
 and Surveying Instruments in the United States, we are enabled to furnish all 
 goods mentioned herein, of the best quality, and at the lowest prices. 
 
 In ordering from this Catalogue it is only necessary to mention this edition 
 and to give the number of the Instrnment or article desired. 
 
 The prices mentioned will be strictly adhered to, except when large quan- 
 tities are ordered. 
 
 "TERMS CASH. 
 
 The safest and best method of remitting money, is by a Bank Draft or Post 
 Office Money Order, made payable to my order. Money Orders can now be 
 obtained for a small sum at most all Post Offices in the United States. When 
 neither of these can be procured, United States, or National Bank Notes, or 
 Postage Stamps, may be remitted by Registered Letter, or sent by express. 
 
 When no satisfactory Baltimore, Philadelphia or New York references is 
 given by the party ordering the goods, the money must accompany the order, 
 or if preferred, the goods will be sent by Express, C. O. D. (collect on 
 delivery), provided the order is accompanied with a remittance of Five 
 Dollars, and when the order comes from West of the Mississippi, the order 
 must be accompanied by a remittance of Ten Dollars. The object of this is 
 to insure the goods being taken, as we have frequently sent goods by Express 
 which have not been taken out of the office, and have had to pay freight and 
 charges both ways. 
 
 The charge for collecting and returning the money will be added to 
 the bill. 
 
 Articles of glass can only be sent by mail at full letter rates, namely, four 
 cents per ounce. Merchandise, not glass, can be sent unsealed, at one cent 
 per ounce. 
 
 Goods ordered to be sent by mail must be prepaid, and the return postage 
 included in the remittance. 
 
 All goods sold by us, are warranted in perfect order, but we assume no 
 responsibility for breakage or other damage, after a package leaves our store. 
 
 Packing boxes will be charged at cost, and all goods will be packed with 
 the utmost care.

 FOR: 
 
 This Blue Process, now extensively used in the Drawing-Rooms of our 
 most prominent Railroads, in Engineers' and Architects' Offices, saves not only 
 much labor and expense, but a great deal of weariness to the junior drafts- 
 man, to whose lot it usually falls to make copies or tracings of drawings. 
 The manipulations required are of the simplest possible kind, and are en- 
 tirely within the skill and comprehension of any office-boy who can be trust- 
 ed to copy a letter in an ordinary press. These particulars are as follows : 
 
 1. Provide a flat board as large as the tracing which is to be copied, or 
 better, a photographic frame specially made for the purpose. 
 
 2. Lay on this board two or three thicknesses of common blanket, or its 
 equivalent, to give a slightly yielding backing for the paper. 
 
 3. Lay on the blanket the prepared paper with the sensitive side uppermost. 
 
 4. Lay on this paper the tracing, smoothing it out as perfectly as possible, 
 so as to insure a perfect contact with the paper. 
 
 5. Lay on the tracing a plate of clear glass, which should be heavy enough 
 to press the tracing close down upon the paper. Ordinary plate glass of ^ 
 inch thickness is quite sufficient. 
 
 6. Expose the whole to a clear sunlight, by pushing it out on a shelf from 
 an ordinary window, or in any other convenient way. In bright sunlight 
 
 LIKE MIDSUMMER, ONLY FOUR MINUTES REQUIRED. A GREAT DEAL DEPENDS 
 
 UPON THE sun's BRIGHTNESS AND HEAT. Frequently when complaints are 
 made about prepared paper, often it is not the fault of the paper, 
 BUT NOT EXPOSED LONG ENOUGH to develop it. Experience will teach you 
 a great deal more than I can. If a clear skylight only can be had, the 
 exposure must be continued for thirty to forty-five minutes, and under a 
 cloudy sky, sixty to ninety minutes may be needed. 
 
 7. Remove the prepared paper and drench it freely for ten minutes or 
 longer, in clear water, and hang it up by one corner to dry. 
 
 The paper should be stored in a dry place, and be entirely shielded from 
 the sunHght before being used. 
 
 The paper is of a full yellow or bronze color. After the exposure to the 
 light the surface becomes a darker bronze or yellowish gray, and the lines 
 of the tracing appear as still darker on the surface. Upon washing the 
 paper, the characteristic blue tints appear with the lines of the tracings in 
 vivid contrast. 
 
 Such copies can be taken from tracings only, either made on tracing-paper 
 or cloth. A very deep black India Ink should be used, as the distinctness 
 of the copies depends thereon.

 DIRECTIONS FOR USING AMSLER'S POLAR PLANIMETER. 
 
 By means of Amsler's Polar Planimeter, a person entirely ignorant of 
 geometry may ascertain the area of any planimetrical figure, no matter how 
 irregular its outlines may be, more correctly, and in much shorter time, than the 
 most experienced mathematician could calculate it. 
 
 The management of the instrument can be easily learned in half an hour, and 
 in size it is no larger than a two-feet folding rule. 
 
 The Planimeter indicates square feet, or square inches, and acres for surveying. 
 
 Directions. — Preparatory to the use of the instrument, ascertain its state. 
 The index roller D must play easily, without coming in contact with the nonius 
 (or vernier). The screw centres, on which its axis revolves, must be adjusted so 
 as to allow perfect freedom of rotation ; the same is to be observed for the centre 
 pin C. 
 
 The needle point E ought to project but very little from its socket. Great care 
 must be taken not to bend any part of the instrument. 
 
 To ascertain the area of a figure in square inches, slide the square rod A into 
 the tube H, so that the line marked 10 sq. in. (10 square inches) stands fair with 
 the beveled part of the tube J. Then set the instrument on the paper, so that 
 the index roller D, the tracing point F, and the needle point E, rest on the paper ; 
 press the latter point a little on the paper — not enough to pierce it through. This 
 point is to remain stationery during the whole operation. Set the tracing point P 
 on any point P of the outline, and mark that point, and read off the state of the 
 counting wheel G, and the index roller D. Suppose the counting wheel indicates 
 3 (as in cut), the index roller 905 (90 degrees to be read on the index roller, and 
 ■^Tj on the nonius), so that the O of the nonius stands on SOj^^^ of the circumfer- 
 ence of the index roller. Write down the number just read off thus, 3,905. 
 
 Now follow, with the tracing point F, the outline of the figure, or part of the 
 figure to be measured, with great exactness, in the same direction as the hands of 
 a watch would move, until you arrive at the starting point. 
 
 Straight lines may be followed along a rule ; then read off again the state of the 
 indicators. Suppose you find now 5,763, i. e. the counting wheel indicating 5, 
 and the index roller and nonius 76j% degrees. From these two readings, the area 
 found is to be obtained, and here two points are to be considered. 
 
 A. If the needle point E is outside of the figure just traced round, the first 
 number (3,905) is to be deducted from the second number (5,763). 
 
 5,768 
 
 3,905 and the remainder (1,858) is to 
 
 be multiplied by ten, equal 18.58 ; 
 
 which is the area desired. 1,858 
 
 B. If the needle point E is inside of the outlines of the figure, add to the num- 
 ber last read off (5, 763) the number marked on the side of the square rod next to 
 where 10 sq. in. is marked on the upper side. 
 
 In this case, it is 20,240, the last number 5,763 read off 
 
 20,240 
 
 26,003 Deduct from this 
 
 amount the number first read off, 3,905 
 
 22,098 Multiply this remainder by 
 ten, equal 220,98, and this is the amount of square inches, or area of the measured 
 figure. 
 
11 
 
 It is of no consequence whether the roller moves inside or outside of the out- 
 lines of the figure, provided it moves on a smooth surface even with the figure. 
 
 To obtain the area in square feet, slide the square rod into the tube up to the 
 line marked 0,1 sq. ft. or 0,05 sq. ft. In this case the difierence between the first 
 and second readings of the indicators is to be multiplied by 0,1 or 0,05. If the 
 difference, for instance, is 4,653, the rod being up to the line marked 0,1 sq. ft., 
 then is 4,653 x 0, 1 = 0,4653 equal to the area in decimal fractions of a square foot. 
 
 If the needle point is within the outlines of the figures as described in B, pro- 
 ceed the same way as at B, but multiply by 0,1 or 0,05. 
 
 If the figure to be measured is at a reduced scale, the result has to be multiplied 
 by the square of the proportion of the reduction. If the proportion of the figure 
 to the full size is as 1 : 10, the result is to be multiplied by 10^ = 100 — for instance : 
 the result of the first example is 1,858, which multiplied by 100 (1,858 X 100) = 
 1858 sq. inches, would be amount of the area. 
 
 If the amount of acres is to be ascertained, the proportion of the reduction being 
 1 : 1000, slide the square rod up to the line marked 2 ac. 1 : 1000, or 1 ac, and 
 operate as indicated above : the result is to be multiplied by 1 or 2, instead of 10 
 or 5. If the rod is set up to the line marked 1 ac, no multiplication is necessary. 
 
 Should the plan of the piece of land be drawn on a smaller scale than j-^^^ — 
 for example, -^7/5 (jth — then multiply the result with the square of the proportion 
 of the reduction to the scale of xTnnr- Thus, for the scale of ^j^^j^, the result would 
 have to be multiplied by 5 x 5 = 25 (^^^^irths being to xAxrtli as 5 : 1). If the 
 scale is ^^^th, multiply the result by ^^ == j, that is to say, divide the result by 4. 
 
 Remark. — If, on reading off the horizontal or counting wheel, G, the indicator 
 points near the middle line between two figures, say between 3 or 4, then see how 
 the index roller stands to the nonius. If the on the nonius is on the lower side 
 of the of the roller, therefore near 100, then read 3 ; but if the on the nonius 
 is on the upper side, therefore near on the roller, then read 4 for unity. 
 
 If the horizontal wheel turns on its axis during the tracing operation, so that it 
 goes beyond (in fact 10), and even marks several revolutions, and then stops at 
 any number — for instance, 7 — you read 17 or 27, «S;c., adding as many times ten 
 as the wheel has made full revolutions. 
 
 It is easy to notice the number of revolutions. If the wheel G marks six', and 
 the roller D is, for instance, on degrees ^g- degrees, or on 4 degrees -^-^ degrees, 
 then the reading is of course 6,007, or 6,047. The number read off the nonius 
 always taking the third place after the units. 
 
 The cut shows the actual size of the instrument. 
 Price in Box $30 00 
 
 Draftsmen, engineers, surveyors, ship builders, architects, machinists, v/ill 
 please devote a few moments only to the examination of this instrument, and they 
 will at once be convinced of its great importance and value.

PREPARED SENSITIVE PAPER, 
 For Copying Drawings : 
 
 To use the Sensitive Paper, first procure a printing frame, lay the drawing 
 faoe down upon the glass, on which place the Sensitive Paper, prepared side down, 
 then several thicknesses of cotton flannel for a pad ; if on turning the frame over 
 any wrinkles appear open the hinged back and place a piece of paper in order to 
 press them out (this should be done in a darkened room), then expose to the sun- 
 light for five or ten minutes, depending on the clearness of the day, remove and 
 examine in a dark room by opening the back of the frame, if the lines are slightly 
 turned in color it has been done properly, remove it and wash in clear water 
 with two or three changes, then dry it. 
 
 The paper must be kept in perfect darkness until used.

"Detalia" is a new article for Drawing purposes. Slightly buff, is less trying 
 to the eyes than ordinary colors. It is very tough, and even in finish, will bear 
 rubbing and is unsurpassed for erasing; it may be erased and drawn upon and 
 again erased without any important deterioration of the surface. It is the best 
 paper in the market to-day for Engineer, Surveyor or Architect use.
