data when considered in conjunction with the weights of the animals actually 

 analysed, and these suggest generalisations on somewhat different lines.

The actual weights of the several constituents in the body of each animal are 

 given in Table II below. The differences between the quantities in the fat 

 animals and those in the lean are regarded as the amounts in the increase 

 represented by the difference in the net weights, and these amounts may be 

 expressed as percentages of the latter.
