    INTRODUCTION. Before entering upon the main object of this work, it is necessary to notice a few circumstances which pertain more especially to Pharmaceutic Chemistry, yet appear to be called for in this place; and, though they are familiar to every educated physician, may be useful to the student who has not yet turned his at- tention to prescriptions. In the first place, it is requisite to be well ac- quainted with the signs of quantityr, or those symbolic characters which are used in writing prescriptions. In the ancient practice of medicine, there were very many of these symbols, not only for the purpose of denoting the quantity of the ingredient, but the in- gredient itself. Most of these, however, have become obsolete ; and a few only are retained as indispensable to the convenience of the practitioner. These will be found in the following table, which is adopted in the Pharmacopoeias for the regulation of weights. English Name. Latin Name. Symbol. Contains. A pound, An ounce, A drachm, A scruple, Libra, Uncia, Drachma, Scrupulus, lb, 3, 3, 12 ounces. 8 drachms. 3 scruples. 20 grains.
