their number to be 8 on each side. They exist in both sexes 
the Sperm Whale; and although visible externally only in 
adult, they may be seen in the young animal upon removing the 
ot pee from the interior of the jaw.— Bennett, Whaling Voyage 
u. 163. 4 
' There is little external appearance, beyond the size of the indi- 
vidual or the development of its teeth, to distinguish the mal 
from the female. Whalers are inclined to believe that the con: 
vex or “ hatchet-shaped”’ snout is characteristic of the male Ca 
chalots, but I do not think that there is sufficient ground for thi 
conclusion.— Bennett, 1. c. 167. q 
Sperm whales are infested with small lice (Larunda Ceti) and 
species of barnacles (as Otion Cuviert), which usually adhere i 
clusters to the integument around the jaws. See Bennett, 1. ¢ 
169; Beale, Hist. Sperm W. 
The ordinary food is the cuttle-fish or squid (Sepia), mam 
kinds of which are rejected from the stomach of the whale whe 
the latter is attacked by the boats. It is probable they oceasio 
ally indulge in other food. In 1835 a School whale rejected from 
her stomach a bony fish more than a foot long. Some whalers 
assert that they have seen Cachalots throw up rock-cod, and ever 
sharks.— Bennett, 1. c. 176. q 
The habitat of the Sperm Whale is more peculiarly the central 
and fathomless water of the ocean, or the vicinity of the most ab- 
rupt coast. The geographical range of the species (genus?) m 
be regarded as very extensive, since no part of the aqueous globe, 
excepting the Polar seas, would appear to be altogether inimical 
to their habits or free from their visits. It is however in the 
warmer seas, within or upon the verge of the tropics, that the 
Cachalot is sought with the greatest success, as in those corre- 
sponding to the intertropical coasts of Africa, America, Asia an¢ 
New Holland, or surrounding the Indian and Polynesian islands, 
but more especially and uniformly in the “line of currents” 
which extend from the equator to almost the seventh degree of - 
north and south latitude, both in the western and eastern hemi- 
spheres.— Bennett, 1. c. 182, with map, showing where they 
occurred during his voyage. They were observed in the Antarctie | 
Seas as high as lat. 71° 50'—Ross, Antarctic Voyage, i. 169, 197. 
Capt. Chase states,—They couple in a horizontal position and 
not upon the side; nor does the female remain supine, but beir 
close to the surface of the water they occasionally turn, so as a 
ternately to bring the top of the head above the water, evidenth 
for the purpose of breathing. The Right Whale breeds at par. 
ticular seasons, but the Sperm Whale at any season of the year 
He has never seen more than a single young one at a time about | 
the old female. Has seen a bucketful of thick rich milk dis:
