In this case the blaze is diphasic, the second phase being larger and more lasting 

 than the first, which is very characteristic. 



At Dr. Alcock's suggestion I syringed out the gall bladder and filled 

 it with NaCl solution, 0'6 per cent., and then tested it ; the effects still 

 occurred in the some order and almost same magnitude, showing that 

 they were due to action in the enveloping gall bladder itself and not 

 to the bile contents. (See experiments of May 7.)
