INDIVIDUAL EXPERIMENTS. 
In the following accounts of the individual respiration expe- 
riments reference is made to digestion experiments. ‘The latter 
were made in connection with the former, but the results are 
detailed in the article on digestion experiments beyond. 
RESPIRATION EXPERIMENTS NOS. I AND 2. - 
The daily routine and details of the first two experiments 
were, from the nature of the case, much simpler than those 
of the later experiments. Improvements were constantly 
being suggested and adopted as the work progressed. ‘The 
analysis of respiratory products are, we believe, sufficiently 
accurate to warrant their publication. However, it is only 
fair to state that these two experiments in particular are looked 
upon as decidedly preliminary. When it is considered that the 
experience was a new one to both the subject and to the observ- 
ers, and that time was required to get the machinery in smooth 
running order, the tentative nature of these two experiments 
is apparent. The kinds and amounts of food were as follows:
