THE CONTROL OF SEX IN BREEDING.

sexual organs. These gentlemen were most certainly mis¬ 
taken ; besides, I can refute that theory by several reliable, 
existing facts. Dr. Sheares, of Santa Rosa, who has served 
as physician in the War of the Rebellion, knows of a soldier 
who lost the right testicle by a bullet shot to have raised 
five children, of which three are boys. 1 know in Santa 
Rosa a man of middle age and good, robust health, who lost 
his right testicle while a young man, married, and with but 
the left testicle glories in the possession of three children, 
all three boys. Almost any physician throughout the coun¬ 
try could report some cases to refute this irrational theory. 
I can merely wonder how the world could exist thousands of 
years without making a good, practical use of this theorv if 
it was true. 
The owners of large cattle ranches, for instance, who wish 
to stop the too rapid increase of stock, instead of spaying the 
heifers in full, would only remove the left ovary from a cer¬ 
tain number of cows, in order to obtain only bull calves that 
would, in time, make steers for the market. 
It is besides a very difficult task, or rather an impossi¬ 
bility to support this lateral sex theory by arguments drawn 
from anatomy and physiology. One can hardly believe that 
nature, which intended to facilitate the reproduction of every 
species of animals it has created, would interpose such diffi¬ 
culties to their natural increase, by subjecting the same to a 
mere hazard. And indeed, the sperm of the male must be 
carried to either one of the two horns of the womb, left or 
right, in order to meet the germ coming from the ovary. 
But suppose that the sperm of the right testis would come in 
contact with the ovum of the left ovary, there would not be 
pregnancy according to that theory, and the purposes of 
nature would be foiled, which is unnatural. The left horn 
would necessarily be destined to develop only a female foe¬ 
tus, and the right horn the male foetus ; but practice shows 
that bull calves are found in the left horn of the cow’s womb, 
and filly colts in the right horn of the mare’s womb. Nor 
has anybody ever observed that in mulipares like the swine 
and canine species, the foetuses were separated in the womb
