Note 15 — THE GATHERER.
Reading edition
Footnote 15: (return) "The ink secreted in this bag has been said to be thrown out to conceal the animal from its pursuers; but, in a future lecture, I shall endeavour to show that this secretion is to answer a purpose in the animal economy connected with the functions of the intestines." (Hume's Comp. Anat. vol. i. p. 376.) Dr. Coldstream, in a letter to the author, detailing the manners of Octopus ventricosus in captivity, says, "I have never seen the ink ejected, however much the animal may have been irritated." I have, however, been told by our fishermen, that they have seen this species eject the black liquid, with considerable force, on being just taken from the sea.
