    Specification. 3 Fox’s Improvements in Treating Cod liver, Castor, and other Oils. effect tlie object of my said Invention as herein-before set fortli, the proportions which I have found to be suitable when employing sulphate of cinchonia or quinine being somewhat as follows, namely, twenty ounces of syrup of sugar, (liquid measure); three grains of quinine or sulphate 5 of cinchonia; four drachms of essence of lemon or of citron; two drachms of oil of aniseed or cloves; and a small quantity, say about three drachms, of spirits of wine. The quinine may be dissolved either in the spirits of wine or in a suitable quantity of water, a quantity of sulphuric acid sufficient to cause the said quinine to dissolve being added to the 10 said water or spirit. I usually add the aforesaid mixture or a mixture similarly made from such substances or materials as herein-before mentioned to about an equal bulk of cod liver oil. When making a preparation of palatable castor oil a mixture made as aforesaid may be added to the said castor oil in the same proportions as when making a 15 preparation of cod liver oil or in other proportions as found to be suitable, but as the quinine or other bitter is not so necessary or advantageous in the case of the castor oil as in the case of the cod liver oil I prefer when making the said preparation of castor oil to dispense with the use of the quinine or other bitter, the mixture in such a case and before being 20 added to the oil consisting only of sweet syrup, spirits of wine, and one or more aromatic flavouring matters of the nature herein-before indicated. In the aforesaid mixture or preparation the proportion of quinine is only intended to be so great as to effect the principal object of my Invention, that is to say, to neutralise the taste of the oil, but a 25 further portion of my present Invention has for its object to increase the medical efficacy of cod liver oil by adding to the said oil such a pro¬ portion of quinine as that each dose of the mixture shall contain a suitable dose of quinine, the said mixture being rendered palatable in manner as has been herein-before mentioned, as, for example, to the 30 proportions of sweet syrup, essence of lemon, and oil of aniseed, or other suitable aromatics as aforesaid I add about one scruple of quinine or sulphate or other suitable salt of cinchonia either with or without the addition of a small quantity of spirits of wine as may be desirable, and I add to such mixture about an equal bulk of cod liver oil or such pro- 35 portion of cod liver oil as may be found to be suitable. The mixture last described I term palatable cod liver oil with quinine. In some cases glycerine may be substituted wholly or in part for the sweet syrup employed in any of the afore-mentioned preparations or mixtures. It may be desirable in order to render either of the herein described
