Fig. 25. — Rabbit 1, Experitnent \. The morning of the day after the injection the number of leucocj'tes reaches 18,000; 

 which is a distinct rise in the number of leucocj'tes in this rabbit. A differential count shows that poly- 

 morphonuclear amphophilic leucocytes constitute 69.6 per cent of the total number. This is rather high. 

 The amount of hemoglobin and number of red cells run in fairly parallel cur\'e3. 

 Rabbit 1, Experiment 2. The number of leucocytes rises immediately after the injection to 25,400, then 

 falls; the next morning the number is again high. Variations in the hemoglobin index seem to fluctu- 

 ate about a nearly constant mean.
