Under precisely similar geological circumstances the _Bos primigenius_ has very frequently been brought to light in Scotland. It is of this animal that Sir R. I. Murchison remarks, in a letter to Professor Owen, descriptive of an example already referred to, found in a bog in Scania: "This urus is most remarkable in exhibiting a wound of the apophysis of the second dorsal vertebra, apparently inflicted by a javelin of one of the aborigines, the hole left by which was exactly fitted by Nillson with one of the ancient stone javelins.... This instrument fractured the bone, and penetrated to the apophysis of the third dorsal vertebra, which is also injured. The fractured portions are so well cemented, that Nillson thinks the animal probably lived two or three years after. The wound must have been inflicted over the horns, and the javelin must have been hurled with prodigious force." Of the existence, therefore, of the _Bos primigenius_ within the historic epoch, we can entertain no doubt, and it is accordingly requisite to give full weight to the influence which its presence must have exercised on the general condition of our island. Professor Owen remarks, after showing the erroneous nature of the usually received opinion, that the lion, the tiger, and the jaguar, are peculiarly adapted to a tropical climate:--"A more influential, and, indeed, the chief cause or condition of the prevalence of the larger feline animals, in any given locality, is the abundance of the vegetable feeding animals in a state of nature, with the accompanying thickets or deserts unfrequented by man. The Indian tiger follows the herds of antelope and deer, in the lofty Himalayan chain, to the verge of perpetual snow. The same species also passes that great mountain barrier, and extends its ravages with the leopard, the panther, and the cheetah, into Bocharia, to the Altaic chain, and into Siberia, as far as the fiftieth degree of latitude; preying principally, according to Pallas, on the wild horses and asses."[28] No change, therefore, of climate, nor any remarkable geological revolution is needful to account for the disappearance of the huge British carnivora, the remains of which abound in the ossiferous caves. They pertain to the closing transition-period of the preadamite earth, and, as in other transition-periods which we shall have to consider, some traces of them survived among the inheritors of the new era. It is therefore a legitimate source of interest to the archæologist, to observe the mingling of extinct and familiar species among the fossil mammals found in the superficial deposits, wherein so much of the evidence of his own science must be sought. It discovers to him the precise link by which his pursuits take hold of the great chain of truth, and in a new sense shews man, not as an isolated creation, but as the last and best of an order of animated beings, whose line sweeps back into the far removed shadow of an unmeasured past.
