We most readily insert the communication of Mr. Raddall. 
He will oblige, and not offend, us by communications of this 
kind. We, however, when we are a little more at leisure, shall 
have a few words to say on the subject.

The Natural History of Horses — The Equidce , or Genus Equus 
of Authors. By Lieut. Col. CHARLES HAMILTON SMITH,

writes very confidently, and describes the Pampas of Southern 
America as being the great sepulchre for these remains. In a 
short essay on “the fossil horse,” which was published in The 
VETERINARIAN by ourselves in the early part of this year, we no-
