Length of Body (Metres) 



Fig. 37. Young Fin whales. Length of body and weight of kidney. 



The weights of these kidneys have been plotted against the length of the whales 

 (Fig. 37). They are extremely scattered in position, but probably lie on some such 

 straight line as that which has been drawn through them. The one female whale has 

 been included in the figure.
