These tables show that, during starvation, the water wasted more rapidly than 

 any of the other constituents of the blood, which became more and more con- 

 centrated as starvation advanced, and hence the apparent increase in its solid 

 constituents in 1000 parts. The blood-corpuscles wasted as well as the albumen, 

 fibrin, and fixed saline constituents. This fact proves that the blood-corpuscles 

 have important offices to fulfil, in supplying the tissues and organs with nutriment, 

 and replacing the organic and inorganic constituents thrown off and consumed.
