Scientific Exploration

Those books are Beale’s and Bennett’s; both in their time surgeons to English South-Sea whale-ships, and both exact and reliable men. The original matter touching the sperm whale to be found in their volumes is necessarily small; but so far as it goes, it is of excellent quality, though mostly confined to scientific description. As yet, however, the sperm whale, scientific or poetic, lives not complete in any literature.

When Captain Sleet in person stood his mast-head in this crow’s-nest of his, he tells us that he always had a rifle with him (also fixed in the rack), together with a powder flask and shot, for the purpose of popping off the stray narwhales, or vagrant sea unicorns infesting those waters; for you cannot successfully shoot at them from the deck owing to the resistance of the water, but to shoot down upon them is a very different thing. Now, it was plainly a labor of love for Captain Sleet to describe, as he does, all the little detailed conveniences of his crow’s-nest; but though he so enlarges upon many of these, and though he treats us to a very scientific account of his experiments in this crow’s-nest, with a small compass he kept there for the purpose of counteracting the errors resulting from what is called the “local attraction” of all binnacle magnets; an error ascribable to the horizontal vicinity of the iron in the ship’s planks, and in the Glacier’s case, perhaps, to there having been so many broken-down blacksmiths among her crew; I say, that though the Captain is very discreet and scientific here, yet, for all his learned “binnacle deviations,” “azimuth compass observations,” and “approximate errors,” he knows very well, Captain Sleet, that he was not so much immersed in those profound magnetic meditations, as to fail being attracted occasionally towards that well replenished little case-bottle, so nicely tucked in on one side of his crow’s nest, within easy reach of his hand. Though, upon the whole, I greatly admire and even love the brave, the honest, and learned Captain; yet I take it very ill of him that he should so utterly ignore that case-bottle, seeing what a faithful friend and comforter it must have been, while with mittened fingers and hooded head he was studying the mathematics aloft there in that bird’s nest within three or four perches of the pole.

Lacépède, the French naturalist, in his elaborate history of whales, in the very beginning of his work (page 3), sets down the Right Whale at one hundred metres, three hundred and twenty-eight feet.
