The bladder contained two fluidounces of clear, light yellow urine, having a 

 slightly acid reaction. Specific gravity, 1002. 



The amount of the urine had been greatly increased, and its character also 

 chemically and physically, had been decidedly changed. 



This subject will be more fully considered hereafter. The stomach was filled 

 with vegetable food, which gave a slightly acid reaction. 



42. Examination of a female salt-water Terrapin (Emijs terrapin) which was 

 deprived of food and drink for twenty-one days, then placed in a tub of fresh water, 

 and abundantly supplied with Purslain (Portulacca oleracea), for thirty-three days, 

 Sept. 17. 



The serum was of an orange yellow color. 



The clot was small, and like that of the blood of Terrapins under the same cir- 

 cumstances, soft. 



The bladder contained about half a fluidounce of clear, light yellow urine, neu- 

 tral to test paper and of low specific gravity. 



The stomach and intestine presented the usual appearance of those of Terrapins 

 which had been treated in a similar manner.

Several other salt-water Terrapins which had been starved, and then transferred 

 to fresh water, and supplied with vegetable food, were examined, and in every 

 instance the results were similar to those recorded above. The following tables 

 will give a condensed view of the effects of these experiments upon the constitu- 

 tion of their blood.
