When, therefore, any large quantity of water in which camphor is diffused is to be prepared at once, it is proper to employ some means for entangling the camphor. Sugaralonedoes not seem to besufficien for the purpose ; and it is more effectually done bytriturating one, or with a portion of sweet in by means of mucilage into an emulsion. It has been thought that the virtues may be increased byexhibiting along with it a portion of nitre; but in many trials I have not been sensible of the benefit derived from the nitre, which, in any quantity that can be conveniently employed, has little effect on the system. It is with more probability alleged, that vinegar exhibited with camphor is of service.

TREE. PREPARATIONS, 1, Campnoratep Mixture. (Mistura Camphorata. L. D.) Take of camphor, one drachm (one scruple, D.); — rectified spirit of wine, a little (fen drops, D.); — double refined sugar, half an ounce; —— ‘boiling distilled water, (water, one pint, D.): tub the camphorfirst with the spirit of wine, then with the sugar; lastly, add the water by degrees, and strain the mixture. 2. CampworateD Emunsion. (Kmulsio Camphorata.. EB.) Take of camphor, one scruple ; -——— sweet almonds, blanched, two drac double refined segar, one drachm ; — water, six ounces: This last is made in the same manner as the common almond emulsion. Neither of these mixtures are very permanent, as the camphorseparates and swims upon the surfacein the course of afew days. As extemporaneous prescriptions, they are, however, very convenient modes of exhibiting that active drug, and may be given to the extent of a table-spoonful every three or four hours in cases of lowness. ‘The latter is the more pleasait remedy, and of equal efficacy. 3. Campnoratep Tincture or Opium. Parecoric Exixir. (Tinctura Opii Camphorata. L.; sive Elixir Paregoricum. D.) Take of hard purified opium, in powder, —— benzoic acid, of each one drachm; camphor, twoscruples; essential oil of aniseed, one drachm ; ——— proof spirit of wine, two pints : Digest for ten days (seven, D.), and strain. In this formula the virtues of the opium and the camphor are combined. It gets an agreeableflavour from the acid of benzoin and essential oil. ‘The latter will also render it more stimulating ; but whetherit derives any salutary virtues from the former, we do not know. It was originally prescribed under the title cf Elixir Asthmaticum, which it does not ill deserve. It contributes to allay the tickling which provokes frequent cough. ing; and at the same time it is supposed to open the breast, and give greaterliberty of breathing. It is given to children against the chincough, &c. from five drops to twenty; to adults, from |
