Book excerpt: Excerpt from Merck's 1907 Index an Encyclopedia for the Chemist, Pharmacist and Physician In presenting Merck's 1907 Index we need bat 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 line chemical products. In order to bring the Index up to date in this edition we have added the newest products, adopted the latest nomenclature, 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. Pharmacop ia, 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 values. 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 each 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).
