    EPITOME OF CHANGES. (3) Tahella.—Another form of lozenge, called tablets, is introduced, but only one article gets the name, and no information as to preparation is vouchsafed. (See Nitro- glycerine, the only remedy of which tablets are official, p. 26.) PROCESSES. Standardising is ordered with a view of securing a constant strength of certain preparations. Thus, Ext. Cinchon. Liq. is to be adjusted to 5 per cent, of total alkaloids. Ext. Opii to about 20 per cent, of Morphine. Ext. Opii Liq. to about 1 per cent, of Morphine. Ext. Nucis Vom. to about 15 per cent, of alkaloids. Aq. Laurocerasi is to be adjusted to o-i per cent, of Hydrocyanic Acid. It seems a pity this last preparation was not expunged from the B. P. altogether. Powdering is now, in some instances, graduated by the method adopted from the U. S. P., of passing the substance through sieves of particular sized meshes. The numbers of the powders are from 40 to 60, and signify the numbers of parallel wires per inch in the sieve required. OMISSIONS. The articles and preparations excluded from the new B. P. are only twenty-two. Those not mentioned in the foregoing groups are as follows :—Areca ; Digitalinum ; Ferri Iodid. ; Ferri Oxid. Magnet.; Ferri Perox. Humid.; Stramonii Folia. A complete list is given on p. 112. Some will regret one and some another of the omissions, but all may console themselves by the reflection that exclusion from B. P. does not forbid the use of remedies, or what should we have done, lo! these eighteen years, without those which were waiting for admission ? Many more will regret that the pruning knife has been so sparingly applied. There would be less objection to retaining articles not often em- ployed if students were not expected to get up minute details concerning them. ADDITIONS. These are 114 in number, but many are only new pre- parations of medicines already official. The additions and other important alterations will now be described at length, under the official names of the respective remedies.
