For being solidified by these means, the substance is no longer soluble in water or miscible with it, and is besides differently acted upon by chemical re-agents. The coagulation of this fluid by heat is considered by the same writer, to be an effect sui generis^ which at present it is impossible to refer to any general principle. •]• The proportion of the ultimate constituent parts of the albumen are stated by M. Thenard to be as follows: 50 carbon, 24 oxygen, 8 hydrogen, 15 nitrogen, in 100 parts of albumen, and in addition to these, on the authority of Mulder, there are present also sulphur and phosphorus.
