Reviews — LyelVs Antiquity of Man. 313 



period" was looked upon formerly as irrelevant to the subject of 

 man's antiquity ; but Sir Charles Lyell now thinks there is good 

 ground for its retention in such a work, seeing that now so much 

 discussion is going on as to the pre- or post-glacial age of man. 



He thinks the third part, treating of " the Origin of Species with 

 reference to Man's place in Nature," is the obvious conclusion to the 

 other parts of the inquiry. 



The works of Sir John Lubbock on "Prehistoric Man," and that 

 of Mr. John Evans on " Ancient Stone Implements," have furnished 

 much new material and many suggestions to the author. 



The theory proposed by Mr. Geikie, and adopted by Sir Charles 

 Lyell, of the rise of land in Scotland to the extent of twenty-five 

 feet in Post-Eoman times, he has now abandoned as being no longer 

 tenable. The evidences and arguments which have resulted in the 

 complete refutation of this theory have been published from time to 

 time in the pages of this Magazine.^ The occurrence of Koman 

 roads and fords suited to the present sea-level and the discovery of 

 a Eoman inscription on a stone at Bo'ness leave no doubt that the 

 present level of the land nearly corresponds with that in Koman times. 



The interesting researches of M. E. Dupont in the caverns of the 

 valley of the Lesse, where this river joins the Meuse, have been 

 recorded in this edition. Out of forty-three caves examined, 25 

 contained traces of man. They are divisible into— (1) the Mammoth 

 Period ; (2) the Eeindeer Period ; (3) the Neolithic, or polished 

 stone period, which is, however, more feebly represented than the 

 other two. 



The careful researches of Mr. Pengelly into the Brixham Cave at 

 Torquay, and the evidence he has accumulated in order to establish 

 the accuracy of the Eev. Mr. MacEnery's statements in regard to 

 the discovery by him of Machairodus teeth in January, 1826, have 

 led to the exhumation of further remains in July, 1872, together 

 with other precious relics, which are duly chronicled. 



Much has been written by Lyell and others regarding the cave of 

 Aurignac, but from the author's last visit, in 1872, accompanied by 

 Mr. T. McK. Hughes, now Woodwardian Professor at Cambridge, 

 he satisfied himself that the evidences of the remoteness of the era 

 to which the existence of sepulchral rites may be carried back are 

 more doubtful than M. Lartet and he had formerly supposed. 



Sir Charles has also visited with Mr. Hughes the caverns of the 

 Dordogne, and has given some account of these interesting prehistoric 

 refuges and of their buried contents. 



Of the two men who undertook the exploration of these caves and 

 the publication of the " Eeliquias Aquitanicae" — Messrs. Lartet and 

 Christy — both are now dead ; but the work is again in progress 

 towards completion, a new part (edited by Prof. T. Eupert Jones, 

 F.E.S.) having just appeared, and another is promised before long. 



The discovery by M. Eiviere of the human skeleton in the cave 

 at Mentone (see Geol. Mag., 1872, Vol. IX. p. 272, with an engrav- 

 ing, and p. 368) is of course duly recorded (p. 143) : —

 VII., p. 270.
