altered. But my observations are too few to determine whether 

 there is any connection between these phenomena or not. 



Another every-day occurrence which is of great importance for 

 most of the above-mentioned functions is the meal-time. In order 

 to test its influence on variations of the leucocytes, I have counted 

 a number of samples of blood taken directly before and after meals, 

 as soon after as the other preceding measurements permitted. These 

 results do not touch therefore the question of the leucocytosis of 

 digestion. The measurements are all from self observations. 



It appears from this series that the number of leucocytes increa- 

 ses during the meal-time, except on the second-last day, when the 

 number of leucocytes after the meal, for some reason unknown to 

 me, falls quite outside the remainder of the series. It appears fur- 

 ther that the number of leucocytes is independent of the rectal 

 temperature, in as much as it increases also on the days, when the 

 temperature owing to previous bodily exercise falls. 



Examination of dried preparations before and after meal-time 

 likewise showed a distinct increase during the meal-time Ч
