Also in this series of investigations the individual fluctuations were 
rather considerable. 
We see that for either subject the average oxygen-intake is higher 
when sitting quietly on the bicycle than when lying in a chair, viz. 
V. H. (lying) average Oxygen-intake 271.1 ce.

N. (lying) 2, 3 255 
(Siting) <=, a 2654 ,, 
We also observe that the average value of the sitting-experiments 
at more than 21'/,° with V.M. is a little higher than that of the 
experiments below 211/,° viz. 
the first value: 344.5, the second 322.5. 
Again, that for MN there is no such difference between the two 
periods. On the contrary with him rather the reverse takes place, 
the first value being 260.8, the second 268.8. However, this difference 
is too small to be taken into account. 
While pedalling W.H. shows an essential increase of oxygen- 
intake, when the temperature rises beyond 21°, at the beginning of 
June. With N the increase is not so great, but it starts a month 
earlier, when the temperature rises bevond 20° viz. 
with V.N. from average 863.4 to 1277.7, nearly 48 °/,
