The San Pablo might have been considered entitled to a "clean bill of health" by the time she reached the equator. The dead left space, food, and water for the living, and very little restraint was imposed on the squalid remnant. None were shackled after the outbreak of the fatal plague, so that in a short time the survivors began to fatten for the market to which they were hastening. But such was not the fate of our captain. The fever and delirium had long left him, yet a dysenteric tendency,--the result of a former malady,--suddenly supervened, and the worthy gentleman rapidly declined. His nerves gave way so thoroughly, that from fanciful weakness he lapsed into helpless hypochondria. One of his pet ideas was that a copious dose of calomel would ensure his restoration to perfect health. Unfortunately, however, during the prevalence of the plague, our medicine chest had one day been accidentally left exposed, and our mercury was abstracted. Still there was no use to attempt calming him with the assurance that his _nostrum_ could not be had. The more we argued the impossibility of supplying him, the more was he urgent and imperative for the sanative mineral. In this dilemma I ordered a bright look-out to be kept for merchantmen from whom I hoped to obtain the desirable drug. At last a sail was reported two points under our lee, and as her canvas was both patched and dark, I considered her a harmless Briton who might be approached with impunity. It proved to be a brig from Belfast, in Ireland; but when I overhauled the skipper and desired him to send a boat on board, he declined the invitation and kept his course. A second and third command shared the same fate. I was somewhat nettled by this disregard of my flag, pennant, and starboard epaulette, and ordering the brig to be run alongside, I made her fast to the recusant, and boarded with ten men. Our reception was, of course, not very amicable, though no show of resistance was made by officers or crew. I informed the captain that my object in stopping him was entirely one of mercy, and repeated the request I had previously made through the speaking trumpet. Still, the stubborn Scotchman persisted in denying the medicine, though I offered him payment in silver or gold. Thereupon, I commanded the mate to produce his log-book, and, under my dictation, to note the visit of the San Pablo, my request, and its churlish denial. This being done to my satisfaction, I ordered two of my hands to search for the medicine chest, which turned out to be a sorry receptacle of stale drugs, though fortunately containing an abundance of calomel. I did not parley about appropriating a third of the mineral, for which I counted five silver dollars on the cabin table. But the metal was no sooner exhibited than my Scotchman refused it with disdain. I handed it, however, to the mate, and exacted a receipt, which was noted in the log-book.
