The Medical Times And Gazette Vol 38

Excerpt from The Medical Times and Gazette, Vol. 38: A Journal of Medical Science, Literature, Criticism, and News; July 3 to December 25, 1858 The addition of alcohol to an aqueous extract may cause the crystalization of some of the immediate principles in the solution which are insoluble, or sparingly soluble, in alcohol, as takes place, for example, when alcohol is mixed with a solu tion of certain inorganic salts in water. It often happens that immediate principles cannot be made to crystalize directly in an extract. We must then endeavour to divide the extract into separate groups of substances or amorphous deposits, from which the immediate principles may be obtained after wards in the crystalized state, or in a chemically pure condition.
