x PREFACE 



It endeavours to look at the horse as the animal 

 appears in the light of the modern and now gener- 

 ally accepted doctrines of Natural History, and in 

 thus doing it may be the means of teaching what 

 some of those doctrines are, and so of affording 

 insight into the methods of nature applicable to a 

 far wider range of study and of thought than that 

 limited to any single species. 



By permission of the publishers of the " Ency- 

 clopaedia Britannica " some passages from my arti- 

 cles on the Horse and allied animals which ap- 

 peared in the ninth edition of that work have been 

 incorporated in this memoir, and I am greatly in- 

 debted to Mr. Gambier Bolton, Major J. Fortune 

 Nott, and Mr. York, for the use of the original 

 photographs from which the figures of the tapir, 

 rhinoceros, and various members of the horse fam- 

 ily have been reproduced. That of the quagga is 

 especially interesting, as being from the only photo- 

 graph known to have been taken of this animal in 

 a living state.
