Other terrapins which had been treated in a similar manner were examined, and 

 the results, in every instance, corresponded with those detailed above. 



We shall next compare these analyses with those of the EmT/s serrafa in its normal 

 condition, and when deprived of food and drink. The following tables will give a 

 condensed view of the changes in the amounts and chemical constitution of the blood 

 of the Emys terrapin during thirst, starvation, and a change of diet.
