nard dog, that gave birth to six male pups, all resembling 
their sire in color and size. 
In some years we hear that more fillies are born than 
horse colts, while in others their numbers are about even. A 
close investigation of the breeding books of our great estab¬ 
lishments might give some very interesting information in 
regard to that matter. Mr. S. Heplar, of the Laymo Ranch 
near Santa Rosa, raised last year, from nine mares, six horse 
colts; while this year the same nine mares, bred to the same 
stallion, brought one horse colt to eight fillies, and he never 
could see any difference in the condition of his horse. Na¬ 
ture always has, and forever will, perform acts that cannot be 
explained by the most acute human intellect, and whenever 
the above physiological principle does not find application, 
all efforts to obtain further light about the mysterious ways 
of nature will be made in vain. 
The article of the North British Agriculturist speaks very 
highly of the only reasonable theory so far, promulgated by a 
German and American physician, namely, that the right testis 
and the right ovary produce male sperm and male germ, 
while the organs of the left side produce the female sex, and 
that the seed of one side would not impregnate that of the 
other side. The experiments those gentlemen have made to 
test the accuracy of that theory have given them results that 
they declare are in accordance with that theory. In evi¬ 
dence they report the following case : There have been for 
several years among the horses of a Danish regiment, in spite 
of all endeavors, some pregnant steeds after the time of pas¬ 
ture. It was known that this had been the case several times 
at the same season, and the watch was particularly active, no 
strange horse having been admitted to the pasture grounds. 
At last they found that among the horses of the regiment 
there was an old stallion whose right testicle had been taken 
out, and all the foals generated by him were fillies.” In all 
certainty that old horse was a ridgling whose left testicle was 
located in the abdomen, and consequently was not a potent 
breeder, and unable to cope in vigor and constitutional 
strength with healthy mares in full possession of complete
