ging to Samuel Barton, Esq., near Bordentown,
New Jersey--had been in labor some eighteen hours; upon an examination
of the animal, the calf was found to be very much deformed, presenting
backwards,--one of the hind-legs having been pulled off by the person or
persons assisting her previous to the author's arrival. Finding it
impossible to deliver her in the usual way, embryotomy was in this
instance employed. By this means, after taking out the intestines,
lungs, etc., of the _foetus_, and cutting away its hind-quarters, the
fore-parts were brought away. The head presented a singular appearance;
the under jaw was so twisted as to bring the front teeth on the side of
the face; the spinal column or back-bone, was turned twice around,
resembling a spiral string; the front legs were over the back; the ribs
were much contorted; the hind-parts were as much deformed; and, taken
altogether, the deformity was the most singular which has been brought
under the author's observation.

FREE MARTINS.--It has long been supposed by stockbreeders, that if a cow
produce twins, one of which is a male and the other a female, the female
is incapable of producing young, but that the male may be a useful
animal for breeding purposes. Many instances have occurred when the twin
sister of a bull has never shown the least desire for the male.

This indifference to sexual commerce arises, doubtless, from the
animal's being but imperfectly developed in the organs of generation.
This fact has been established by the investigations of Mr. John Hunter,
who had three of these animals slaughtered for anatomical examination.
The result is thus reported: "The external parts were rather smaller
than is customary in the cow. The _vagina_ passed on, as in the cow, to
the opening of the _urethra_, and then it began to contract into a small
canal, which passed on into the division of the _uterus_ into the two
horns; each horn passed along the edge of the broad ligament laterally
toward the _ovaria_.

"At the termination of these horns were placed both the ovaries and the
testicles. Both were nearly of the same size, which was about as large
as a small nutmeg. To the _ovaria_, I could not find any Fallopian
tube.

"To the testicles were _vasa deferentia_, but they were imperfect. The
left one did not come near the testicle; the right one only came close
to it, but did not terminate in the body called the _epididymis_. They
were both pervious and opened int
