LOUIS. MO. RAHWAY. N. J. 3. 15 UNIVERSITY PLACE 9 CopyRight, 1907, by MERCK & Co., NEW YORK. PREFACE In presenting Merck's 1907 Indea, we need but refer to the popularity of previous editions and to point to the title page of the work, which fully shows its scope and defines its field of usefulness to the chemist, the pharmacist, and the physician– in other words, to the users of drugs and fine chemical products. In order to bring the Index up to date in this edition we have added the newest products, adopted the latest nomen- clature, consulted the most modern authorities, and, for the Merck products, verified the data in our laboratories and our Works. - Furthermore, we have added the crude drugs of commerce and have indicated under each drug the dose of its extracts, tinctures, fluid extracts, etc., instead of grouping all extracts, tinctures, etc., together as in the previous editions of the Index. We have given the specific gravities at 15° C.; in many cases, following the U. S. Pharmacopoeia, we have also given them at 25° C. As the Index is not intended to be a price-list we give no prices, but instead we give what may be called comparative walues. That is to say, wherever possible We have placed a number opposite the name of the product, and if such a number is compared with the numbers at the foot of eagh left-hand page the comparative value of the article so numbered will be at once apparent. For instance, Duboisine Sulphate Merck bears the number 875, its value lies, therefore, between that of Gold Tribromide Merck (the comparative value of which is 570) and that of Eserine Sulphate Merck (the comparative value of which is 1111). Or again, if neither of these two products suggests anything very definite, 875 can be considered as approximately 4 x 225, or 16 × 55, or 20 × 44, or 35 x 25, or 80 × 11, or 175 × 5, or 220 × 4, or 300 x 3, or 400 x 2, or 900 x 1; and consequently the value of Duboisine Sulphate—bearing this number 875– is about 4 times that of Aconitine, 16 times that of Morphine Sulphate, 20 times that of Veratrine, 35 times that of Strych- nine, 80 times that of Silver Nitrate, 175 times that of Iodoform, 220 times that of Potassium Iodide, 300 times that of Guaiacol, 400 times that of Salol, and 900 times that of such cheaper articles as Cerium Oxalate or Calcium Hypophosphite. Some of these products are familiar to every one and can, therefore, be used as an easy basis for comparison. Another point to which we wish to draw attention, as we were questioned frequently in regard to it in connection with previous editions of the Index, is the means by which products Inay be known to be obtainable of the Merck brand. For that purpose we have put the designation Merck after the name of every product procurable of the Merck brand. On page 299, for instance, Nicotine and its salts; Nigrosine; Niobium and its compounds; the various isomers of Nitraniline; and Nitran- isol (Ortho), are to be had of the Merck brand: whereas Nigella Damascena, Nigella Sativa, Nikiforoff’s Borax-Carmine, and Nirvanin are not. Merck’s products being the standard, We cannot recommend too strongly for the sake of accuracy of results and uniformity of action, that when ordering such arti- cles as bear this designation Merck, you should always Specify MERCHK’S on your orders.

N.B.-Occasionally practitioners fail to recol- lect, until after the disagreeable occurrence, that chloroform rapidly decomposes when its vapor comes into contact with an exposed gas-light, evolving peculiar chlorine vapors which are extremely irritating to all present and may be even dangerous to the patient. Chloroform, therefore, should never be administered by gas- light unless the latter be well protected by a closed glass case, and abundant provision made for the rapid escape from the room of all decomposition products. Note.—Purified by specially devised, careful processes, & freed from all poisonous foreign substances, Chloroform Merck for Anesthesia is particularly adapted for use as an anesthetic, as well as in all work of an exacting nature. do.

The decomposi- tion is rendered still slower by the presence in each vial of about 10 drops of a very dilute solution of soda.

Radium Etymol.: Fr. Lat. “radius,” a ray, referring to the luminous & o. rays given off by the element. Discovered in 1898 by Mme. Curie, in pitch- blende.—Ra.—Radium has not been isolated as such in the free state. It is marketed chiefly as hydrobromide, the salt being of varying radioactive strength acc. to its purity. Its strength is denoted by numerals showing the relation to an absolutely pure salt, the radio- activity of which is designated arbitrarily as 1,000,000 or even higher. The salts of radium possess the power of imparting radioactivity to other substances by contact or exposure, the substances then also becoming radioactive.— Uses: Therapeutically, in lupus, cutan. tu- bercul., Superficial epithelioma, cancer, &c. The salt, inclosed in a sealed glass tube, is brought near or fastened to the affected part, & the rays allowed to impinge for a sufficient time. On the healthy skin, the rays may cause Severe & obstinate burns that heal very slowly.
