A few days before our departure some of the scientific staff had further opportunity of communicating with the "blacks." It was important to extend our collection of craniological specimens for that branch of study, by comparing the various races of men with each other, so as to enlarge our knowledge of the physiological peculiarities of either sex and every race; and as we had been told that numbers of skulls could be procured among the _Gunyahs_, or sandstone cavities of Cook-river Bay, which had been a favourite burial-place of the aborigines, we made an excursion thither, still accompanied by our staunch friend, Mr. Hill. Our light vehicle rattled merrily through the suburbs of New Town, a sort of suburb of Sydney, thence over the Cook-river Dam, 1000 feet wide by 200 feet in length, to Coggera Cove, where several of the aborigines had pitched a temporary camp. These were two Mestiza women with their children, and Johnny, the last of the Sydney blacks, who might be about 40, and was a cripple in consequence of an injury sustained in childhood. In 1836 there were 58 still alive; now Johnny is the last remaining survivor! We set off from Coggera Cove in a small, but safe, and well-built boat, rowed by Johnny and some white colonists, bound for Cool-river Bay, but our search in the sandstone caverns was unfortunately fruitless. Johnny then conducted us to a spot where Tom Weiry, one of the last of the chiefs, who lived at the mouth of Cool River, and died about twelve years previous, had been buried. Tom Weiry, or Tom Ugly, as the English named him, was a very athletic man, whose skeleton was a real prize for the purposes of comparative anatomy. Close to the spot where, according to Johnny, the last remains of the Australian chief reposed, were large quantities of empty oyster-shells, indicating that the place in question had once been a favourite resort of the "blacks," attracted thither by the prolific yield of this place in those shell-fish, one of their most highly appreciated articles of food. At various spots traces of fires were visible. The aborigines of the coast usually bury their dead clothed in the woollen blanket they wore in life, with the heads seaward, and near the coast, with but a few feet of earth over them. Unfortunately we had our pains for our reward, although Johnny repeatedly assured us he had himself, in picking up shell-fish, on that very spot seen projecting from the sand human bones, that frightened the superstitious fellow from prosecuting his search in that direction. Indeed, Johnny was positive some other exploring naturalist had been there and walked off with our contemplated anthropological prize.
