EFFECTS OF THIRST, ETC., ON EMYS TERRAPIN. 



87 



By a careful comparison of the results of these experiments upon the Yellow- 

 bellied Terrapins {Emys serrata) and the Salt-water Terrapins {Emys terrapin), we 

 discover the following effects of starvation, thirst, and a change from animal to 

 vegetable food. 



The blood lost during starvation was rapidly restored, in amount, upon a vege- 

 table diet. 



The proportion between the moist blood-corpuscles and liquor sanguinis was not 

 altered in any great degree. 



In most instances, the solid constituents of the blood were less under a vegetable 

 than under an animal diet.
