a process which presents three definite phases of regulation of the 

 water content in the organism. First comes a period of rapid 

 loss in weight, when proportionally more dry substance than water 

 is lost, the per cent of water, therefore, increasing. This is followed 

 by a period of rather slow decrease in weight, when practically no 

 water is lost, and when the regenerative activity and the water 

 content both reach a maximum. Lastly there comes a period dur- 

 ing which proportionally more water than dry substance is lost, 

 the per cent of water thus declining.
