appears to corroborate.

MR. BYNOE'S OBSERVATIONS ON THE MARSUPIATA.

"My first examination," says Mr. Bynoe, "of the kangaroo tribe, to any
extent, occurred at the Abrolhos; there I had an extensive field for
ascertaining the exact state of the uteri of the wallaby of those
islands. I opened between two and three hundred, and never found even the
rudiments of an embryo; but in the pouch I have seen the young adhering
to the nipple from the weight of half a dram to eight ounces and upwards.
On examination, the only substance found in the womb when the animal was
young and full grown, was a cheese-like substance of a straw colour: I
likewise found a similar substance in the pouch around the nipples, and
in many instances where the nipples were much retracted, it completely
covered them, but it was of a darker hue than that in the uterus, and of
a saponaceous or greasy feel; the aperture of the pouch so much
contracted as scarcely to admit two fingers; wombs with their cornua
remarkably small, and nipples in the pouch scarcely pointing, and in many
instances retracted.

"Animals with these appearances, I concluded, had never borne young.
Examinations frequently took place immediately after they were shot. In
those that had recently discarded their young from the pouch, one nipple
and frequently two were found much lengthened, and very often one more
than the other. I have seen them in the wallaby frequently two inches in
length, and with pouches so large, that you could with ease thrust your
hand into them; the uteri with their appendages enlarged and apparently
very vascular, as well as thickened; but in no one instance at the
Abrolhos could I detect a gravid uterus; but I have seen the young
adhering to the nipples less than half an inch in length, and in a
perfectly helpless state. It is generally supposed that the uterus in the
adult animal is not supplied with much arterial blood, merely sufficient
to nourish that viscus. If such be the case, can it have the power of
retaining the germ in the womb, when on the most minute examination of
the young, I could not detect, by cicatrice or line of abrasion on any
part of the abdomen, that they ever possessed umbilical vessels, or had
been in any way nourished by a placenta? Let us take into consideration
the small size of the animal found in the pouch, its utter helplessness,
its slight power of motion, and its firm attachment to the
