Camphor (clean), 4 1 ⁄ 2 oz.; rectified spirit, 1 gall.; di olve. This forms the ‘ ESSENCE OF CAMPHOR ’ and ‘ LIQUOR CAMPHORÆ ’ of the wholesale houses. About 1 ⁄ 2 fl. dr., added to 7 1 ⁄ 2 fl. dr. of cold distilled water, forms (by agitation) a transparent aqueous solution of camphor, fully equal in strength to the filtered ‘ MISTURA CAMPHORÆ ’ (camphor julep) of the Ph. L. The above made with weaker spirit forms the ‘spirit of wine and camphor’ of the shops. 2. Camphor, 1 oz.; rectified spirit, 10 oz. (by weight); di olve. This forms the ‘ CONCENTRATED ESSENCE OF CAMPHOR ’ of the wholesale druggists. 10 or 12 drops, added to 1 fl. oz. of pure cold water, make a transparent camphor julep, as before. There is a large quantity of these solutions of camphor sold by the London houses, who charge a considerable price for them. They are very convenient for preparing extemporaneous camphor julep or camphor mixture in dispensing. 3. (Fordred.) Tincture of camphor, 13 fl. dr.; tincture of myrrh, 1 ⁄ 2 fl. dr.; rectified spirit, 18 1 ⁄ 2 fl. dr.; mix. 1 fl. dr., added to 4 fl. oz. of water, forms camphor julep. It has been proposed to bleach the tincture of myrrh with animal charcoal, but this interferes with its proper action. 4. (Homœopathic.) See Cholera remedies , Nos. 6 and 7. 5. (Houlton.)
