Table showing the Rate of Growth of the Whiting {Gadus merlangus), 



after Cunningham. 



I must notice here the case of a whiting which I kept living under 

 observation in one of the small tanks of the laboratory, from a month 

 or so after hatching until it was one year and four or five montlis old. 

 When first placed in the tank, in early May, 1902, this whithig 

 measured 10-20 mm. in length (according to Cunningham the larval 

 whiting when first hatched is 3-G mm. in length). The whiting in 

 question was fed regularly from the hand until July 4th, 1903, when 

 it leapt from the tank. At the latter date it measured 8| inches in 

 length, and was 3^ oz. in weight. On examining its scales I found
