    quantities of the ingredients taken to form the preparation, not from the quantities which exift in it after it is formed. The nitrate of mercury, for example, in the different ointments yito which it enters, is ellimated as equal to the whole quantity of mercury and nitrous acid employed to form it, although, from the very nature of the preparation, it cannot be fo much. In the folutions of opium, the opium is ellimated as equal to the whole quantity'employed, although not above two-thirds of it be diflblved. Laftly, no al- lowance is made for the lofs by evaporation; and hence, notwith- ftanding the difference by calculation, the Edinburgh troches of liquorice with opium contain probably as much opium as thofe of Dublin; for the former being made with fyrup, they will lofe more in drying than the latter, which are made with extt»dl of li- quorice.
