In the opinion of Bougainville, these people were the same that had been seen by the Etoile in 1765; for he says, that one of his present sailors, who was then on board that vessel, distinctly recognised one of them.  They were well shaped, and their height was estimated at betwixt 5 feet 5 inches, and 5 feet 10 inches French; or in English, measure, 5 feet 10,334 inches, and 6 feet 2,5704 inches.  They appeared gigantic, it is added very properly, because they had very broad shoulders, their heads were large, and their limbs thick.  They were robust and very muscular, and seemed to enjoy perfection of health, and to possess abundance of wholesome diet.  Their figures, notwithstanding the dimensions, were far from being coarse or unpleasant; on the contrary, many of them might be esteemed handsome.  The peculiarities of their features were, a round and somewhat flat face, very fiery eyes, uncommonly white teeth, and long black hair which was worn tied on the top of the head.  In the colour of the skin, they did not differ from other Americans.  Some of them had their cheeks painted red.  The language they used is said to have been very delicate.  The description now given of these people, it must be remarked, applies to the men, for hitherto none of the women had been seen.  In dress they nearly resembled the Indians residing about the Rio de la Plata.  A piece of leather served them for an apron, and a cloak of skin fastened round the body with a girdle, hung as far down as their heels, but had besides a part, generally allowed to fall down also, which might occasionally cover their shoulders, though this was not often done.  They did not seem very sensible to the cold of the climate, which, even at this season, viz. their summer, was only ten degrees less than that which freezes water.  Their legs were covered with a sort of half boot, open behind; and some of them, wore on the thigh a copper ring about two inches broad.  That they had had acquaintance with Europeans was still more clearly manifested by sundry articles amongst them, of which are mentioned particularly little iron knives, supposed to have been given them by Commodore Byron a short time before.  Their horses were bridled and saddled in the same manner as those of the inhabitants of Rio de la Plata; and one of these bulky cavaliers had gilt nails at his saddle, wooden stirrups covered with copper plates, a bridle of twisted leather, and an entire Spanish harness.  Here did not appear to be any thing like superiority of rank or subordination established among them; nor could it be remarked, that three old men who were in the party, received any peculiar marks of esteem from the rest.  Bougainville gives it as his opinion, that these savages lived somewhat in the manner of the Tartars, traversing the immense plains of South America, living almost constantly on horse-back, and subsisting on such fare as their hunting expeditions, if not their pillaging ones, brought them in.
