TELEGONY, WITH OBSERVATIONS ON THE 

 STRIPING OF ZEBRAS AND HORSES, 

 AND ON REVERSION IN THE EQUID^. 



Introductory. 



Op the still sui^viving ancient and widespi-ead beliefs, 

 one of the most suggestive and interesting to students of 

 nature is the belief that parents hand on to their offspring 

 some of the peculiarities acquired during their lifetime; in

 to a Boer-like faithin the teaching of the Old Testament, I am 

 unable to say. But assuredly breeders of Aberdeen- Angus 

 cattle have not been singular in believing in the power of
