male and female Parents on their Offspring . 
female ass and the horse, nor even a delineation, or descrip- 
tion of its form ; but I do not entertain any doubt that its chest 
and shoulders are excessively deep and strong, comparatively 
with the length of its legs, and that, on account of this pecu- 
liarity in its form, it has been so frequently shewn on the 
Continent, under the name of a jumart, as the pretended off., 
spring of the mare and the bull. 
In opposing the theory advanced by Mr. Cline, it is not by 
any means my intention to enter the lists with him, as a phy- 
siologist ; but, as a farmer and breeder of animals of different 
species, I have probably had many advantages, which he has 
not possessed ; and my conclusions have been drawn from 
very extensive, and, I believe, accurate observation. 
There is another respect in which the powers of the female 
appear to be prevalent in their influence on the offspring, and 
that is relative to its sex. In several species of domesticated, 
or cultivated animal ( I believe in all ) , particular females are 
found to produce a very large majority, and sometimes all 
their offspring of the same sex; and I have proved repeatedly, 
that, by dividing a herd of thirty cows into three equal parts, 
I could calculate, with confidence, upon a large majority of 
females from one part, of males from another, and upon 
nearly an equal number of males and females from the re- 
mainder. I frequently endeavoured to change these habits 
by changing the male ; but always without success ; and I 
have in some instances observed the offspring of one sex, 
though obtained from different males, to exceed those of the 
other, in the proportion of five or six, and even seven to one. 
When, on the contrary, I have attended to the numerous off- 
spring of a single bull, or ram, or horse, I have never seen
