Investigations into the conditions governing tiie temperature of tlie bodз^ 21 



indicated appears distinctly; but the practically complete parallelism 

 between the two curves indicates that the action of the heart is 

 one of the factors which determine the rectal temperature. 



The curve of the pulse is the best marked of the two curves, 

 giving on an average the greatest fluctuations, especially for the 

 maxima and minima, which is quite reasonable, as the rectal tem- 

 perature is the secondary function i. In the two upper double curves, 

 both derived from self observations, on days with some bodily 

 exercise — the one from the "inverted" day - inversions occur in 

 the forenoon, derived from the comparatively greatly increased 

 frequency of the pulse after breakfast. In the third curve, derived 

 from another individual on a day wàth sedentary work, the rise 

 after the last meal is absent, which is no doubt due to the fact,

that the temperature was not measured immediately after this meal 

 and that the person concerned ate unusually little on this occasion. 

 The agreement between morning temperature and frequency of 

 the pulse day by day is more difficult to prove, but no doubt 

 exists. The difficulty is due to the pulse. In the morning on 

 waking, there is as a rule a more or less distinct desire to micturate 

 and this accelerates the frequency of the pulse, often rather consider- 

 ably; after micturition the frequency of the pulse decreases and 

 after a short time rises again.

The curve shows the relation between temperature and pulse 

 in daily, morning measurements; as the relation dealt with above 



^ Investigations by Воск (Arch. f. exper. Pathologie u. Pharmacologic. Suppl. 1908 

 Pag. 8;}). Make it probable that the relation between the frequency of the pulse 

 and the temperature is rather more complicated.
