    RELATION OF MEASURES OF CAPACITY OF THE BRITISH PHARMA- COPCEIA TO THE METRICAL MEASURES. I Gallon == 4*543487 litres. I Pint - 0*567936 ,, or 567*936 cubic centimetres. I Fluid ounce = 0*028396 ,, 28*396 ,,, I Fluid drachm = 0*003549 „ 3*549 >> I Minim = 0*000059 ,, 0*059 ,, RELATION OF THE METRICAL WEIGHTS TO THE WEIGHTS OF THE BRITISH PHARMACOPCEIA. I ]\Iilligramme I Centigramme I Decigramme I Gramme I Kilogramme = 0*015432 grs. - 0*15432 „ = 1*5432 = 15*432 = 2 lbs. 3 oz. 119*8 grs. or 15432*348 grs. RELATION OF THE METRICAL MEASURES TO THE MEASURES OF THE BRITISH PHARMACOPCEIA. • I Millimetre = o *03937 inches. I Centimetre = 0*39371 ,, I Decimetre = 3*937o8 ,, I Metre = 39*37079 ,, or I yard 3*7 inches. I Cubic centimetre = 15*432 grain measures. I Litre = i pint 15 oz. 2 drs. ii m. or 15432*348 grain measures. All liquids are ordered by measure unless it is stated otherwise. It will be seen that the solid drachm and the scruple have been omitted from the Pharmacopceia; if the signs 3j and 9j are still made use of, they- will represent sixty and twenty grains respec- tively, and not the eighth and twenty-fourth part of the avoir- dupois ounce. The avoirdupois fluid ounce corresponds to the solid ounce, in the case of distilled water at 60° Fah. ; that is, one fluid ounce weighs exactly an oimce. A minim of distilled water, however, does not weigh one grain, as the fluid ounce is divided into 480 minims ; the solid ounce into 437*5 grains only. GROUPS OF PHARMACOPCEIA PREPARATIONS. The following remarks concerning certain groups of pharma- ceutic preparations contained in the British Pharmacopoeia may prove of service to the reader, by^ enabling him to discover at a glance the nature of their more important general characters, and facilitating the understanding of some peculiarities in nomenclature and methods of preparation found in many of them.
