These are the most recent, and probably the most accurate 

 of any of the analyses of human bone yet published. We 

 may omit, from absolute superfluity of matter, the researches 

 of Schreyer, E/ees, Thilenius, Sebastian, Davy, Frerichs, and 

 Stark, which refer merely to the estimation of the organic and 

 inorganic matters, and shall take a brief survey of the more 

 perfect analyses of bone.
