I have in the next place to draw attention to a striking qualitative or morphological peculiarity observable in no less than three out of my six Bushman crania; this being the presence either of a perfect, or of a rudimentary division of the malar bone into two distinct parts. The skull presented by Dr. Bleek presents us with a perfect rectangular suture, bilaterally symmetrical, as is usually the case with this suture both when it is and when it is, as here, not, rudimentary. In the two skulls, 788_e_ and 788_g_, collected by Mr. Frank Oates, the suture is rudimentary, being represented in each skull by a bilaterally symmetrical fissure running horizontally forwards from the zygomatico-malar articulation.[69] When I add to these observations the fact that similar sutures have not within my knowledge and research been observed in other African crania of any of the varieties living on that continent, it will be seen that the presence of them in these skulls goes a considerable way, when coupled with other considerations, towards making it pretty certain that they were of Bushman nationality. Further investigation of the distribution and non-distribution of this most significant suture amongst the several typical races of men, lends some additional force to this argument, and is besides not a little suggestive as to other views. In the Oxford University collection of crania I have not found any traces of it amongst 47 Australian, nor amongst our five Tasmanian crania, nor amongst our Stone age crania, a series well represented here. The only other race of indisputably pristine and very pristine habits, in which I have observed it to exist, is the Eskimo, and out of a large number of such skulls I have only noted it once, in the form of bilaterally symmetrical fissure. The other skulls which this museum contains possessing this suture either well or rudimentarily developed, are six in number. Four are presumably either of the Malay or of the Chinese race, as two were collected by Captain Elmhirst of the 9th Regiment, from the sea-shore of an island in the Chinese Seas, out of a great quantity which were lying about unburied, and were supposed to have belonged to Chinese pirates, and were finally presented to the University museum by the Rev. H. Hansell, Fellow of Magdalen College; as a third was the skull of a female Moro, collected in the mountains of Sulu, and presented by Captain Chimmo, R.N.; whilst the fourth was purchased from Mr. Cutter, the dealer in Natural History specimens, as being a Borneo pirate. The other two are from Ceylon, one being a Tamil from Central Ceylon, presented by Mr. B. F. Hartshorne, who was himself for a considerable time resident in the island, and has written upon its ethnology; the other being a “Malabar.” As the absence of this suture from the Zulu and Negro series gives additional importance to its presence in the Bushman, so its absence, which I have noted in
