period of experimentation. The pulse was a rule steady. My pulse 

 is for the rest very sensitive, any slight trouble with the putting 

 together of the apparatus would be sufficient to produce the varia- 

 tions shown here. 



We have in the series for April 1907 (p. 101) altogether 13 com- 

 plete experiments, all from the mornings, made immediately after 

 dressing; further 1 experiment, where the gas-analysis was unsuccess- 

 ful. The gas-analysis is, however, also doubtful in two other ex- 

 periments (30 and 36); in the first case, the temperature of the bath 

 showed a rise of 0"5° between the first two readings, a difference 

 strikingly great, even when allowance is made for the difficult con- 

 ditions in the room. This experiment is in several regards so diver- 

 gent, that I have thought it best to exclude it entirely from the 

 series, the reasons for which will be discussed more fully below 

 under the separate elements of the series. As my notes on the ex- 

 periments at this time are scarce, I cannot give any reason for the 

 divergence beyond what has just been said. In the second case (36) 

 the control reading showed the height of the mercury in the analy- 

 sing apparatus to be 03 of a division lower, with a simultaneous 

 rise in the temperature of the bath of 01°; this is also a difference 

 which is probably due to greater errors (that the absorption-liquid 

 has given off gas, for example), but the experiment is otherwise 

 quite normal. Two experiments (34 and 35) Avere interrupted, as 

 the stop-watch was not going; both were completed immediately 

 afterwards by the help of another watch. Experiment No. 40 w^as 

 also interrupted and begun again, as the outlet-tube from the samp- 

 ling receiver was stopped up by some dirt in the mercury. The 

 sampling in this and the following experiment was not quite uniform. 

 These small disturbances have, however, scarcely any influence on 

 the results of the experiments. 



The bodily weight has decreased evenly during the period of 

 experimentation. The mouth temperature was measured daily- 

 before the beginning of the experiment; it gives, however, scarcely 

 any information regarding the physiological condition of the orga- 

 nism, as it appears to follow very closely the movements of tem- 

 perature in the room. 



The pulse is somewhat high and varies not a little; on the first 

 day it was taken (like the temperature) when recumbent before 

 dressing, on the following days wlien sitting up after dressing. The 

 causes for the variation in the pulse, especially in a downward 

 direction, will be discussed under later experiments. 



On several days during the experiments the temperature in the
