29. Blood of Female Yellow-bellied Terrapin [Emys serraia), which had been 

 kept without food or drink for twenty-six days.

Loss of weight during twenty days .... 5.480 " 

 In twenty-six days this terrapin had lost from one-fourth to one-fifth of its whole 

 weight. Loss of weight each hour, llyVo gi^ains, = a-gVi^^^ ^^^^ original weight of 

 its body. 



This Chelonian was in a feeble state, and in all probability M^ould not have lived 

 many days. 



"When its tissues and organs were examined it was found that the yellow fat, 

 which is so abundant in these animals, had disappeared, having been consumed for 

 the maintenance of the animal function, and in the supply of the wastes of the 

 tissues and organs. The destruction of the fat was observed to be one of the con- 

 stant effects of starvation. 



The amount of blood obtained was not more than one-half as much as that 

 obtained from a much smaller terrapin, which was killed only a few days after its 

 removal from the water.
