Chart 3. — Variations in weights of dogs VIII, XI, XII, and XIV of Experiment III. 



Dogs numbers VII, IX, and X were killed on the eighteenth day of the 

 experiment through the same accident by which animals I, II, and III 

 were lost. Only four dogs Avere left, these being comparable more by
