I have trouble believing that in the 1830s, when Dana is writing about his voyage, that such an educated person as he was could be so ignorant about scurvy, or that the captain could have been so stupid, particularly when as shorthanded as he was, risked losing the ship because of men
being unable to do their duty!

"The scurvy had begun to show itself on board. One man had it so badly as to be disabled and off duty, and the English lad, Ben, was in a dreadful state, and was daily growing worse. His legs swelled and pained him so that he could not walk; his flesh lost its elasticity, so that if it was pressed in, it would not return to its shape; and his gums swelled until he could not open his mouth. His breath, too, became very offensive; he lost all strength and spirit; could eat nothing; grew worse every day; and, in fact, unless something was done for him, would be a dead man in a week, at the rate at which he was sinking. The medicines were all, or nearly all, gone; and if we had had a chest-full, they would have been of no use; for nothing but fresh provisions and terra firma has any effect upon the scurvy. This disease is not so common now as formerly; and is attributed generally to salt provisions, want of cleanliness, the free use of grease and fat (which is the reason of its prevalence among whalemen,) and, last of all, to laziness. It never could have been from the latter cause on board our ship; nor from the second, for we were a very cleanly crew, kept our forecastle in neat order, and were more particular about washing and changing clothes than many better-dressed people on shore. It was probably from having none but salt provisions, and possibly from our having run very rapidly into hot weather, after having been so long in the extremest cold."
And to think that the Yankees had made fun of British lime juice for quite a few decades!
