Not illustrated. 1853 edition. Excerpt: ...of lipyl, which may be separated in the form of glycerine. Lehmann regards them as haloid salts, formed by the combination of a haloid base with an organic acid, and he places together the oxides of ethyl, methyl, and lipyl, as belonging to the same series of compounds. They are also analogous in composition to what Gmeliu calls ethers of the third class, and acetate of the oxide of methyl, one of these bears a certain degree of analogy in its chemical constitution to fats and oils. Again, spermaceti is the cetylate of the oxide of cetyl, and the hydrated oxide of cetyl is considered by chemists to be closely allied to the alcohols, in fact a species of alcohol. It is not unworthy of notice that, nearly a century ago, cod liver oil was recognised as a remedy of no mean value, though its efficacy in consumption continued unknown; also that suet dissolved in milk was known as a remedial article of diet in consumption in the time of Dr. Young. Yet it is strange that two such Dr. Winkler states that he has lately found that cod liver oil differs in composition from all other oils hitherto used in medicine in this respect, that when saponified with potash it does not yield glycerine, but oxide of propyle, a new body which exists in combination with the oleic and margaric acids, taking the place of the oxide of lipyl in other oils and fats. By means of oxide of lead this body may be separated in a higher state of oxidation as propylic acid. By means of ammonia it may likewise be converted into an alkaloid profacts should not have been placed together, especially as other kinds of oil and fat had been known to have proved serviceable in consumption, and that thus the discovery should not have been sooner made of the applicability of cod liver...
