cent, and the cases in which the larger animals have the greater 

 nucleus, thirteen out of eighteen cases, or 72 per cent. The 

 averaged values given at the bottom of each column in table 

 5 show that the larger animals possess larger cell bodies and 

 nuclei, though the average differences are very slight indeed.

The average body weight of the larger animals is 99.6 grams, 

 while that of the smaller ones is 81.2 grams; the ratio between 

 them being 1:0.82. The ratio for the cell bodies is 1:0.99 and 

 the ratio for the nuclei 1:0.97. Thus the difference found in 

 the cell bodies and the nuclei in the two groups is relatively 

 slight and much less than that in the average body weights. If
