Excerpt from Chemistry of Animal Bodies The object of the present work is to lay before the British public as complete a view as I can of the present state of the Chemistry of Animal Bodies. This branch of Chemistry is much more difficult than the chemical investigation of vegetable bodies. The difficulty does not lie in the analysis, for accurate and simple methods of analyzing animal bodies as well as vegetable have been devised , but in separating the different animal bodies from each other, and obtaining each in a state of purity. These processes with respect to vegetable bodies are much facilitated by the property which they have of crystallizing. Unfortunately the most important animal substances, as albumen, fibrin, gelatin, casein, &c., want that property. The consequence is, that we have no good criterion for determining when these bodies arc pure, or what the substances are with which they are mixed. The consequence of this difficulty has been, that the greater number of modern chemists have confined their investigations to those animal substances, assugar, cholesterin, cetin, urea, &c., which are capable of crystallizing. I am not aware of any modem British chemist who has attempted to investigate any animal substance incapable of crystallizing.
