172 THE ZOOLOGIST. 



known to have inhabited, with a reference to the animals whose 

 remains are associated with his rude flint implements. Full 

 of suggestion also are the comparisons between the faunas of the 

 periods of palaeolithic and neolithic culture. 



In the chapters devoted to the " Specific unity " and the 

 "Varietal diversity" of Man, the arguments used on these 

 points by anthropologists are well worthy of consideration by 

 general zoologists ; and when we remember the very elastic use 

 of the terms species and variety necessarily made by mono- 

 graphists and descriptive naturalists, we may somewhat incline to 

 the dictum of our author, who writes : — " It is not always easy to 

 draw the line between species and mere variety, more especially 

 as to neither of these terms is any longer attached the idea of 

 finality." 



In the second division of his work Mr. Keane discusses the 

 " main divisions of the Hominidce, and, adopting Linne's original 

 fourfold division, divides his subject under the following classifi- 

 cation :— " Homo JEthiopicus," " Homo Mongolicus," " Homo 

 Americanus," and " Homo Caucasius." * 



In conclusion, we will advise the reader to bear in mind an 

 excellent remark in the author's preface : "In a work of this 

 nature, dealing with a multiplicity of subjects on all of which 

 nobody can be supposed to have personal knowledge, it is not to 

 be expected that the views advocated, or even the mere statements 

 of facts, will be always accepted on the ipse dixit of the writer. 

 Hence the necessity of constant reference to received authorities." 

 These are abundantly quoted throughout, so fully indeed that a 

 student who would with an open mind refer to and fully read the 

 references given by Mr. Keane — either with approval or dis- 

 approval — could not fail to obtain a somewhat complete grasp of 

 anthropology. And this we consider is the province of a good 

 hand-book, not to dogmatise or inculcate a canon of scientific 

 faith, but to present the whole subject to the enquirer, and not 

 only guide him to the good roads, but mention also the jungle- 

 paths where investigation is not always barren. 



* It is at least worthy of remark, that in two contemporaneous standard 

 works, both bearing the imprimatur of Cambridge, and written by writers so 

 diverse in thought as Mr. Keane and Dr. Sharp, and on animals so widely 

 separated as Man and Insects, a reversion to the system of Linnaeus should 

 in each case have been more or less followed.
