Quotations
There is another substance, and a very singular one, which turns up in the course of this business [of preparing sperm whale], but which I feel it to be very puzzling adequately to describe. It is called slobgollion […] It is an ineffably oozy, stringy affair, most frequently found in the tubs of sperm, after a prolonged squeezing, and subsequent decanting.
1892, Herman Melville, Moby Dick, page 394
