    Translation:— Take (of) Potassium Acetate three drachms Tincture Digitalis one drachm Syrup of Orange six drachms Infusion of Broom to^ six ounces Mix. Let a mixture be made A consideration of the foregoing example will show that the quantities are in the accusative case, being the objects of the verb take thou (recipe)^ and the in- gredients are in the genitive case. The subscription is usually confined to simple directions, as : fiat^ mistura (let a mixture be made); fiant pilulae (let pills be made); fiat lotio (let a lotion be made); misce (mix); signa (label); signetur (let it be labelled). Having decided what drugs he intends to administer, the prescriber first determines the dose of each necessary, and the quantity of vehicle requisite to dissolve, or to hold in suspension, the constituents so that the prepara- tion may be suitable for administration. Lastly, he decides the number of doses, which will be regulated by the length of time he wishes the medicine to be taken, and by the proneness of it to undergo decomposition. Calculation of the quantities.

It will be noticed that Infusi Scoparii ad ovj places the in- gredient in the genitive case which is the common form of writing it when followed by ad, but some writers place the ingredient in the accusative. 2 The verb Fio takes a nominative after it.
