41. Examination of a female Emys terrapin which had been starved twenty-one 

 days, then placed in fresh water, and abundantly supplied with Purslain. 



It consumed large quantities of this vegetable, and was kept in the water for four 

 weeks, Sept. 9.

 the latter required for its coagulation about thirty minutes. 



The Fibrin was much softer than that of Terrapins in the normal condition.
