It is, of course, only practicable to display these 

 observations in a roughly quantitative manner. The 

 actual numbers of food animals present in the alimentary 

 canal of each fish were not counted, and only approximate 

 estimates of the abundance of each constituent of the 

 food were made. It is, nevertheless, possible to shew 

 roughly what is the commonest food of each fish. In 

 the following table the numbers of black dots represent 

 the number of fishes in which the food animals noted in 

 the adjoining columns occurred exclusively. Each full 

 dot represents two fishes.
