Many other principles have been met with possessed of pe¬ 
culiar properties, but their characters in general have been so 
obscure, or their purity so uncertain, that they have not been 
distinguished by any appropriate names. 
In regarding the above list, we cannot help remarking how 
much this department of the science owes to Chevreul. Almost 
the only branch of animal chemistry which has been thoroughly 
investigated is that of the fatty bodies; and for nearly everything 
that has been done in it we are indebted to that distinguished 
chemist. 
Abstract of a Comparative Review of Philological and Physi¬ 
cal Researches as applied to the History of the Human 
Species. By J. C. Prichard, M.D. F.R.S. 
The object of this Essay is to furnish a survey of the progress 
of knowledge in relation to ethnography, with a critical ac¬ 
count of the attempts which have been made to distribute the 
human species into departments constituting what are termed 
families of nations, and especially of that classification of races 
which has been adopted by Baron Cuvier, and is now very
