“ ON THE PHYSIOLOGY OE BREEDING.— 
By R. Orton, M.R.C.S., Sunderland.” 
In reply to the series of Questions suggested by Mr. Varnell, 
in the July Number of this Journal, we have been favoured 
with a copy of Two Lectures under the above title ; and in 
furtherance of the object we had in view, we shall give 
our readers an epitome of their contents. The author 
lays down two laws, substantiated by a mass of interesting 
evidence, as well as a large number of cases, which he 
considers bear out his premises. These laws he thus 
enunciates : 
“ 1. That the male gives the external configuration, or in 
other words, the locomotive organs ;* while the female gives 
the internal, or in other words, the vital organs. t 
“ 2. That the female system imbibes certain influences from 
the male, which modify her future progeny by other males.” 
Law 7 I. — The first illustration of this law he deduces from 
the cross between the horse and the ass; and he shows 
that the produce of the stallion and the she ass (the hinney) 
is essentially a modified horse; whereas the mule, the produce 
of the male ass and mare, is essentially a modified ass. This 
is, moreover, borne out by the fact, that the hinney neighs, 
whereas the mule brays. Dr. Danvin had stated, as long 
ago as 1799, that the temper and habits of an animal 
were due to the female parent. 
“ Cow-breeders,” we are told, “ are very careful in the se- 
lection of the best milkers, and those derived from a maternal 
* “ Such as the skin, the muscles, and the bones.” 
j* “ Which are the lungs, the liver, the stomach, the bowels, and the 
appendages.”
