and eleven. In the sea.son of 1882 Captain Gray alone kille<l 
two hundred and three out of a tohil of four hundred and three 
hrought home. The proportion of ages and sexes killed by Captain 
Gray Avere as follows Ninety-six old males, fifty-six cows, and 
li tty-one younger males. From one of the cows killed on the 28th 
^lay , and which measured twenty-nine feet in length, a young one 
was taken, measuring ten feet ten inches in length, by five feet six 
inches in girth. Captain Gray had the skull of this fcetal AVhale 
cleaned; but, unfortunately, tlie ro^ie by which it hung overboard 
jiarted, and it Avas lost. 
It Avill be seen that Captain Gray’s great experience of these 
animals for the past two seasons enables him to speak with 
authority; and there can be no <piestion that he is correct in 
Ins strongly-expre.s.sed opinion that the great differences in the 
skull and external appearance observed in these strange creatures 
IS sexual, and gradually assumed as maturity is reached. 
Iherc are .some curious points of similarity betAveen the Fottle- 
nose halo and the Sperm AVliale in addition to those of food 
and habits. The commercial products yielded by them are almost 
Identical; the head contains the “case” and “junk ” of the latter 
species ; and the oil is little, if any, inferior to the true sperm oil 
its market value being about .£G0 per ton. ’ 
At the approach of Avinter these creatures retire from the 
Arctic seas and disperse to the South. .Alost of the individuals 
occurring on our coasts are met with in the autumn ; and from the 
fact ot tlic old females being so freipiently accompanied by their 
young. It seems probable that their meeting in such numbers in 
the Northern Ocean is for purposes maternal and matrimonial- 
after which, like the Seals, which visit the same seas in such vast 
numbers, they disperse and resume their solitary AA-anderin- 
(.aptam Gray has certainly rendered a great service to .science lii 
s udying the habits of these animals, and in making known the 
results of his investigations he has solved one of the most iiressiim 
problems in Cetology. °
