PEOTECTIVE INOCULATION 



257 



Babbits Nos. 5 and 6. 



Both these animals were for the first time injected intravenously 

 on July 1 with 5 cc. of Haffkine's prophylactic : — 



From this it appears that intravenous injection of the prophy- 

 lactic was followed by a little less decisive rise of temperature than 

 was subcutaneous injection in the former cases. The body weight 

 fluctuated considerably — fluctuation which was on the whole fairly 

 parallel for the two animals ; that is to say, when it rose in one it 

 rose also in the other rabbit, and vice versa.
