Use "isinglass" in a sentence

1. Now, however preposterous it may at first seem to talk of any creature's skin as being of that sort of consistence and thickness, yet in point of fact these are no arguments against such a presumption; because you cannot raise any other dense enveloping layer from the whale's body but that same blubber; and the outermost enveloping layer of any animal, if reasonably dense, what can that be but the skin? True, from the unmarred dead body of the whale, you may scrape off with your hand an infinitely thin, transparent substance, somewhat resembling the thinnest shreds of isinglass, only it is almost as flexible and soft as satin; that is, previous to being dried, when it not only contracts and thickens, but becomes rather hard and brittle

2. That same infinitely thin, isinglass substance, which, I admit, invests the entire body of the whale, is not so much to be regarded as the skin of the creature, as the skin of the skin, so to speak; for it were simply ridiculous to say, that the proper skin of the tremendous whale is thinner and more tender than the skin of a new-born child

3. But these marks do not seem to be impressed upon the isinglass substance above mentioned, but seem to be seen through it, as if they were engraved upon the body itself
