Altogether 30 measurements were made on 4 different individuals. 

 The highest number of leucocytes was in all cases found in the r 

 position and the change must therefore be regarded as certain, even 

 though the differences are much less than in the experiments of 

 Hasselbalch and Heyerdahl. The reason for the small difference 

 is most probably, that the blood was not taken directly after the 

 change in position, as a period of 10—20 minutes must be reckoned 

 to the first three determinations. 



As I have shown in a previous paper, the mouth temperature 

 falls on taking the r position, whilst the skin temperature on the 

 head rises. The transition from the s to the r position has there- 

 fore the following results. 



Pulse frequency decreases 



Calibre of artery decreases 



Diastolic blood-pressure decresesa 



(Pulse-pressure increases) 



Temp, in mouth falls 



Temp, on forehead rises 



Number of leucocytes increases 



The above measurements were all made on "fasting" individuals, 

 i. e. shortly before meals. If the investigation were made after 

 meal-times, we should find certain changes in the above scheme, as 

 both the calibre of the arteries and the mouth temperature are 

 often quite the reverse and the "leucocyte reaction" is also generally
