184 NOTES AND EXHIBITS. 



be estimated at about thirty feet long. This monster has one of 

 these arms extended over a fishing boat, one of the occupants of 

 which, is drawn as in the act of striking with a large knife at this 

 huge tentacle, as thick as a man's body, where it crosses the 

 gunwale. For my own part, I am inclined to suppose that the 

 picture is by no means an exaggeration, but that it is drawn from 

 actual fact. This Octopus is not longer than other specimens, 

 portions of which have recently been obtained and subjected to 

 scientific observation on the coast of the North-west Atlantic. It 

 will be seen that he is moving in the normal manner of his tribe, 

 backwards. The break of the sea around his body and arms is 

 plainly intended to indicate this. The colour of both body and 

 arms is a monotonous brownish-drab, very different from the 

 varied and beautiful tints of the smaller octopods. As in these 

 latter their chameleon faculty of changing the colour of their 

 external surface is related to, or (as I should say) designed for, the 

 protection of the weaker individuals, one can readily understand 

 why in such Hydras as this under our eyes all shyness and 

 shrinking from public observation may reasonably have been 

 surrendered. I have entered into these details only because 

 they seem to corroborate the truthfulness of the general represen- 

 tation.
