The number of blood-corpuscles appears to be very great, but it is so only in 

 appearance and not in reality ; for, the amount of blood in the Chelonian is very 

 small, and the blood-corpuscles correspondingly few in number. The whole amount 

 of blood, obtained with great care, did not exceed 200 grains.

If the starved terrapin, and the one in a normal condition possessed originally 



equal quantities of blood, having the same chemical constitution, then the starved 



terrapin must have consumed, during fifty-seven days, 800 grains of blood, having 



the following constitution : —

In noting the changes of the constituents of the blood of the Emys terrapin during 

 starvation, we might be led into error if the relative quantities of the different con-
