One coarsely granular leucocyte met in counting through 2,000 leucocytes in 



cover-glass preparations. The films, both fresh and dried, show obvious but 



not extremely severe leucocjtosis. 



Under these conditions of experiment the changes in the blood of 

 the general circulation resembled in their main features the results 

 observed in the experiments of series (I). I will not therefore 

 recapitulate the results. I will merely add that the addition of 

 nucleated cliromoblasts to the blood seemed less uncertain in these 

 experiments than in the experiments on the limb. 



A modified form of the experiment consists in simply ligating the 

 knuckle of intestine, and returning it with aseptic precautions into 

 the peritoneal cavity. This modification, although the same main 

 changes in the blood were as before brought about, did not give quite 

 the same sequence of events. I quote examples. 



Dog. Example. 



9 P.M. Was fed at noon. Temperature, 39. Respiration, 22. 



Sp. gr. of blood from ear 1'058 



Haemoglobin value 50 



Sp. gr. of blood serum (slightly milky) .* T0275 



Number of chromocytes in mm. blood 2,502,000 



leucocytes in mm. blood 6,260
