Moby Dick by Herman Melville Chapter 94 Page 7

There is another substance, and a very singular one, which turns up in the course of this business, but which I feel it to be very puzzling adequately to describe. It is called slobgollion; an appellation original with the whalemen, and even so is the nature of the substance.

It is an ineffably oozy, stringy affair, most frequently found in the tubs of sperm, after a prolonged squeezing, and subsequent decanting. I hold it to be the wondrously thin, ruptured membranes of the case, coalescing.

Gurry, so called, is a term properly belonging to right whalemen, but sometimes incidentally used by the sperm fishermen. It designates the dark, glutinous substance which is scraped off the back of the Greenland or right whale, and much of which covers the decks of those inferior souls who hunt that ignoble Leviathan.
