in January 472, in August 521 litres per hour. The difference is 49 

 litres or almost 08 litre per minute, which gives 32 cc. COg or 

 192 cc. per hour. Taking the bodily weight as 68 kilos, we have 

 23 cc. per kilo, and per hour; it will at once be seen that this 

 quantity is in this connection quite without importance. 

 The series for the year becomes:

After the explanation given above, it is permissible to exclude 

 experiment No. 132 from the first series, the average of which would 

 then become 193 + 06, p. = 27. Further, it will certainly be 

 most correct to exclude experiment No. 36 from the second group 

 of the April series, as there is some uncertainty about the gas-ana- 

 lysis in this, otherwise normal experiment (see p. 102). It will be 

 best, therefore, in this connection to take the following values.

The experiments made at a low temperature will be discussed 

 more in detail below. If further experiment No. 98 is omitted, we 

 have for the series of January:

With regard to the November experiments, it has already been 

 mentioned several times, that they were made shortly after a journey, 

 which made continuous demands on increased metabolism, in the 

 day-time owing to considerable muscular work, at nights in order 

 to thaw the frozen sleeping-bags. At the same time the declining 

 sunlight was used to the very utmost, much more than usual when 

 staying at a fixed station. After the journey I continued to eat more 

 than under ordinary conditions, resulting in an increase of weight, 

 which rose a little during these experiments, whereas it decreased 

 in the other experimental series. 



It is possible that the large value for January in comparison 

 with the results of the control experiments, is due to the after- 

 effects of the journey; it is likewise possible that the temperature 

 has something to do with it. These experiments were made at a
