For Flask to have presumed to help himself, this must have seemed to him tantamount to larceny in the first degree.
It was fair to presume that being a harpooneer, his linen or woollen, as the case might be, would not be of the tidiest, certainly none of the finest.
Least of all, did Flask presume to help himself to butter.
There are three whales and three boats; and one of the boats (presumed to contain the missing leg in all its original integrity) is being crunched by the jaws of the foremost whale.
Yet not to speak of the peril of the thing, it is to be doubted whether this course is always the best; for it is but reasonable to presume, that the longer the stricken whale stays under water, the more he is exhausted.
Like some poor devils ashore that happen to know an irascible great man, they make distant unobtrusive salutations to him in the street, lest if they pursued the acquaintance further, they might receive a summary thump for their presumption.
If a stranger were introduced into any miscellaneous metropolitan society, it would but slightly advance the general opinion of his merits, were he presented to the company as a harpooneer, say; and if in emulation of the naval officers he should append the initials S.W.F. (Sperm Whale Fishery) to his visiting card, such a procedure would be deemed pre-eminently presuming and ridiculous.
It was hardly to be doubted, that several vessels reported to have encountered, at such or such a time, or on such or such a meridian, a Sperm Whale of uncommon magnitude and malignity, which whale, after doing great mischief to his assailants, had completely escaped them; to some minds it was not an unfair presumption, I say, that the whale in question must have been no other than Moby Dick.
Should any unwarrantably pert young Leviathan coming that way, presume to draw confidentially close to one of the ladies, with what prodigious fury the Bashaw assails him, and chases him away!
Moreover: we are to consider, that from the presumed great longevity of whales, their probably attaining the age of a century and more, therefore at any one period of time, several distinct adult generations must be contemporary.

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?
I know not that any other author has hinted of the matter; but by inference it seems to me that the sturgeon must be divided in the same way as the whale, the King receiving the highly dense and elastic head peculiar to that fish, which, symbolically regarded, may possibly be humorously grounded upon some presumed congeniality.
Though, in these cases, the direction taken by any one whale be straight as a surveyor’s parallel, and though the line of advance be strictly confined to its own unavoidable, straight wake, yet the arbitrary VEIN in which at these times he is said to swim, generally embraces some few miles in width (more or less, as the vein is presumed to expand or contract); but never exceeds the visual sweep from the whale-ship’s mast-heads, when circumspectly gliding along this magic zone.
But no sooner did the herd, by some presumed wonderful instinct of the Sperm Whale, become notified of the three keels that were after them,—though as yet a mile in their rear,—than they rallied again, and forming in close ranks and battalions, so that their spouts all looked like flashing lines of stacked bayonets, moved on with redoubled velocity.
By these means, the circumnavigating Pequod would sweep almost all the known Sperm Whale cruising grounds of the world, previous to descending upon the Line in the Pacific; where Ahab, though everywhere else foiled in his pursuit, firmly counted upon giving battle to Moby Dick, in the sea he was most known to frequent; and at a season when he might most reasonably be presumed to be haunting it.
But though when she had thus sailed a sufficient distance to gain the presumed place of the absent ones when last seen; though she then paused to lower her spare boats to pull all around her; and not finding anything, had again dashed on; again paused, and lowered her boats; and though she had thus continued doing till daylight; yet not the least glimpse of the missing keel had been seen.
Owing to a confident reliance upon other means of determining the vessel’s place, some merchantmen, and many whalemen, especially when cruising, wholly neglect to heave the log; though at the same time, and frequently more for form’s sake than anything else, regularly putting down upon the customary slate the course steered by the ship, as well as the presumed average rate of progression every hour.
There are no more uses of "presumption" in the book.
