wheel, or to that of the arterial elasticity, by which intermittent force 

 effects constant flow. The blood acts as a chloroform reservoir (or as 

 an ether reservoir if ether be the anaesthetic employed). 



In the firat experiment we compared manometrically the absorptive 

 power of blood and of water by introducing a known volume of each 

 liquid in the two identical closed flasks connected with two petroleum 

 manometers, and previously filled with chloroform and air of identical 

 percentage. 



The figures of a first trial were as follows for 50 c.c. of blood* and 

 of water respectively in flasks of 600 c.c. capacity filled with chloroform 

 vapour at 17 per cent. : 



A second trial, with the blood and water transposed, and the flasks 

 charged by chloroform and air at lower CHC1 3 percentages gave :
