[55] Ipsum cremare apud Romanos non fuit veteris instituti, terra condebantur.—Hist. Nat. lib. vii. c. 54.
[56] Cases occur where the original tumulus has been adopted as a place of sepulture long subsequent to its original construction. Care is therefore required to discriminate between superficial interments of late date, and the original cist or urns; but it is rarely difficult to detect the evidences of intrusion. The slight depth at which they are generally interred affords in itself a striking contrast to the labour exercised by the constructors of the sepulchral mound. It is also to be borne in remembrance, that all the urns found in tumuli are not sepulchral, or proofs of cremation.

[58] Dr. Hodgkin read a paper at the meeting of the British Association, held at York in 1844, on the dog as the associate of man, chiefly with a view to shew how much the study of the inferior animals which, by accident or design, have accompanied man in his diffusion over the globe, is calculated to throw light on the affinities of races.
