has also occurred on other days without causing any apparent 

 deviations in the results. The agreement of these experiments with 

 those made on the cold days in April has already been mentioned. 

 The calculated limiting values of the series are 2223 and 2537. 

 The average is 238 + 1"5, ц = 77 or 32 ^'/o of the average. 



The series for August 1907 is so well-defined and uniform, that 

 in spite of its small number of experiments I must consider my 

 respiration as sufficiently well characterised at this time. 



Of the 10 experiments only 8 are complete, the gas-analyses in 

 the first two experiments being unsuccessful; the gas-sample was 

 too small, giving rise to a negative pressure in the burette, which 

 rendered the analysis impossible. The outlet-tube was changed, but 

 it appeared that the mercury ran out too quickly from the new 

 tube; the taking of the samples in experiment No. 59 was therefore 

 not continuous but piecemeal. This had no influence, however, on 

 the progress of the experiment, as I was able without difficulty to 

 reach the outlet stop-cock; and as the respiration was regular, I 

 believe that the air-sample taken gives a correct average value. 



Defæcation occurred once in the day during the period of 

 experimentation, as a rule in the evening; but there were two ex- 

 ceptions, on the 16th it occurred immediately after the experiment 

 and apparently affected the respiration during this, on the 19th 

 immediately before the experiment. 



The pulse was throughout lower than in the previous series; 

 but the source of error mentioned above has distinctly made its 

 influence felt. 



The rectal temperature was taken immediately after waking 

 up, thus before dressing; it varies very little, but is on an average 

 slightly less than the average value of my morning temperatures, 

 probably because I got up earlier than usual during the period of 

 experimentation and was therefore very sleepy, so soon after being 

 wakened. 



The bodily weight was only determined once during the period. 

 From weighings taken outside the range of the table, however, I 

 can conclude, that the weight has been the same during the whole 

 period. 



The respiration frequency was regular in the separate 

 experiments. In one case only (No. 62) I have noted that the frequ- 

 ency was not so regular as usual, and that I twice felt myself uncer- 

 tain as to the number; I consider the number given as reliable, 

 however. The abnormally high frequency in experiment 60 is cer- 

 tainly due to the desire to defæcate \Nhich arose during the experi-
