THE following equivalent formulae have been prepared in order to be a convenience to the pharmacist when preparing quantities in Imperial weights and measures. The formula give only the proportions of the constituents and quantities to be used in the process of manufacture; for the method the pharmacist is referred to the B.P. 1932. It should be noted that the quantities given here in the Imperial system are not the equivalent of the individual quantities given in the B.P. in the metric system; therefore, whichever formula is used the quantities specified in that particular formula must be adhered to throughout.

Liquids should be measured in all cases unless the contrary is specifically indicated. It should be noted that the Imperial system is standardised at a temperature 16-7� (62�F.), at which temperature 1 mil of water weighs somewhat less than 1 gramme, therefore, in making percentage w/v solutions with Imperial weights and measures to correspond with the percentage w/v preparations of the B.P. it is necessary to take 438.47 gr. (approximately 438� gr.) as equal to 1 oz. In the following formulae this has been the basis of calculation, but as it often leads to inconvenient fractions the figures have been rounded off for the sake of practical convenience. Where inconvenient fractions occur, it will usually be found that the nearest half grain or minim, up or down, can be reckoned.

Abbreviations: � gr. = grain; m. = minim; oz. = ounce; fl. oz. = fluid ounce; p.c. = per cent; q.s.=in sufficient quantity; w/v=weight in volume.
