THE PENYCUIK EXPERIMENTS 



By PBOFESSOR J. C. EWAET, F.R.S. 



KOMULUS (SEVEN DAYS OLD) AND HIS DAM, MULATIO 

 One of the Illustrations. 



" I liave no space to go into the scientific details of these matters as set 

 out by Prof. Ewart, but I may say at once that though all such points are 

 clearly made they are dealt with in such a manner as that he who runs may 

 read. There is nothing wearisomely technical from start to finish."- 

 Sportsman. 



"Science is much indebted to Prof. Ewart for the interesting, elaborate, 

 and costly experiments that he has so successfully conducted at Penycuik. 

 It is these original investigations mainly that render the book under con- 

 sideration so eminently worthy of careful study by the practical breeder, the 

 theoretical evolutionist, and the naturalist alike." Annals of Scottish 

 Natural History.
