    INTRODUCTION. illKiiEiy mediuiues are viewed from a pliariuaceiltical aild imedioal aspect; references to their use, with the doses em- I'ployed, are given in precis. The area of selection is limited by personal experience. Modern official drugs are still noticed, and older ones are introduced wlien unofficial prepara- ?tion3 of them are in use, or their preparations have undergone satteration. In the Secondary List of drugs will be found those ito which medical attention lias been more or less directed, but nwhich have not come into general use. The Index forms a copious IPosological Table. The doses are based on personal experience, or are culled from the best authorities. The terms Drachm and ' Ounce, when applied to liquids, are understood to be the iriuid IDrackiu and Fluid Ounce respectively, as defined by the 'British Pliarmaoopa'ia. E.vcept in some foreign formulas where liquids are ordered to be weighed, when parts are referred to iCsolubilities included), it is to be understood that ounces and fluid ounces, grains and grain-measures, or grammes and culiic centimetres are to be emph>yed. In regard to the formula; for hypodermic injections and several others, as a iminira is not equal to a grain-measure, and as hypodermic ■syringes and dispensing measures are graduated in minims, for •practical purposes the use of ' parts ' is generally avoided 'when referring to these small quantities. They are therefore ordered in grains and minims or ounces (i.e. fluid ounces) ; tluislnjectio Morphina- Acetatis Hypodermica contains 1 graia of Morphine Acetate in fj minima. Exceptions to this rule are clearly indicated. Specific grauties and solubilities have ■been determined at 15'5° C. (60 F.). Percentage solutions are sometimes mentioned, by which it is intended that 100 grain-measures of the finished solution ■sliall contain n grains of the substance, or that 100 Cc. shall contain n Gm.; e.ii. a .50 i)er cent, solution of Cocaine Hydro- chloride will contain 50 grains in 100 grain-measures, and will dilute with an equil volume of liquid to form a 25 per cent. • solution. Liquids are in nearly all cases directed to be measured, but in a few instances, where it would tend to greater convenience 'Kiid accuracy, c.(j., oils, glycerin, the strong mineral acids and •oleic acid, the quantities are ordered to be weighed.
