But as druggists and medical practitioners constantly employed measures, in defiance of the prohibition, and as the practice, besides being attended with great and obvious convenience, was found to be less fraught with danger than had been conceived, the London College in the first instance, and subsequently the other colleges also, recognized a system of measures of their own, founded on the standard measures of the country. The Colleges of London and Edinburgh, adopting the imperial pint of 1826 as the basis, divide it into twenty parts, called fluidounces; each of which corresponds exactly with an avoirdupois ounce of distilled water at 62° F. and 30° bar., and therefore contains 437.5 grains troy. The fluidounce is subdivided into eight parts of 54.6875 grains, termed fluidrachms ; and each of these consists of sixty parts, called minima, which therefore amount each in weight to 0.91146 troy grains of distilled water. [The Dublin College, at the last revision of its Pharmacoposia in 1851, adopte('. the same standard for measures; so that all the British Colleges now use the Impe- rial pint and its subdivision of twenty fluidounces.—Ed.]
