Voyagers and sportsmen conversant with photography are re- © 
quested to take the instantaneous photograph of the animal: this 
alone will convince zoologists, while all their reports and pencil- 
drawings will be received with a shrug of the shoulders. 
As these animals are very shy, it is not advisable to approach 
them with a steamboat. 
The only manner to kill one instantly will be by means of explosive 
balls, or by harpoons loaden with nitro-glycerine; but as it most 
_ probably will sink, when dead, like most of the Pinnipeds, the 
harpooning of it will probably be more successful. 
If an individual is killed, take the following measurements: — 
1. Length of the head from nose-tip to occiput. — 2. Length of the 
neck from occiput to shoulders. — 38. Length of the trunk from 
shoulders to tail-root. — 4. Length of the tail from tail-root to 
end. — 5. Distance from shoulders to fore-flappers. — 6. Distance 
from shoulders to thickest part of the body. — 7. Length of a fore- 
flapper. — 8. Length of a hind-flapper. — 9. Circumference of the 
head. — 10. Circumference of the neck. — 11. Circumference of the 
thickest part of the body. — 12. Circumference of the tail-root. 
Give a description of the animal, especially an accurate one of 
the head, the fore-flappers and the hind-flappers, and, if possible, 
make a sketch. 
If but barely possible, preserve the whole skeleton, and the 
whole skin, but if this is utterly impracticable, keep the cleaned 
skull, the bones of one of the fore-flappers and those of one of the 
hind-flappers, four or five vertebrae of different parts of the backbone, 
neck, and tail; and preserve the skin of the head, and a ribbon of 
about a foot breadth along the whole back of the neck, the trunk, 
and the tail.
