Attention is particularly directed to the Synopsis or Index of Diseases in Part II.; it is not pretended that the modes of treatment therein detailed are the best which could be adopted; the object has rather been to show how much good may be effected by the simple means at command at almost every "upcountry station" throughout India; and those who follow the directions may feel assured, that with the exercise of ordinary prudence, if they fail to do good they will at any rate do no harm. LONDON, 1874. [Footnote 1] To these Bromide of Potassium and Biniodide of Mercury have since been added. INTRODUCTION. This work, it is presumed, will fall into the hands of many who are wholly ignorant of, or very partially acquainted with, matters pharmaceutical; hence some few introductory remarks are indispensable to enable such persons to understand fully, and follow out correctly, the directions given. 1. _Weights and Measures._—In Appendix C, a small set of Apothecaries' scales and weights is included, but in the absence of the former it is well to remember that a small set of scales, such as is used by native jewellers, can be procured for a few annas in every bazaar; care, however, is necessary to see that the balance is strictly correct and even. _Weights._—The Apothecary weights supplied from England have the following marks or signs impressed upon them: ℈fs = half a scruple = 10 grains. ℈j = one scruple = 20 " Ʒfs = half a drachm = 30 " Ʒj = one drachm = 60 " Ʒjfs = one drachm and a half = 90 " Ʒij = two drachms = 120 " The small circular indentations on the grain weights indicate the number of grains each weight represents. In the absence of these, the following hints may be useful: A new rupee of the present currency weighs 180 grains or three drachms. A half rupee of the present currency weighs 90 grains or a drachm and a half. A quarter rupee of the present currency weighs 45 grains or three quarters of a drachm. To obtain smaller weights beat a new quarter rupee into a long, thin, narrow plate, and divide it carefully into three equal parts. You have thus three 15 grain weights. One of these divided again into three equal parts, furnishes three 5 grain weights. One of these subdivided into five equal parts furnishes five 1 grain weights. Care should be taken to see that the parts are of equal weight, and each part should be marked with a figure to denote its weight. A native jeweller, at a very small cost, will readily carry out the above subdivision.
