We shall now fulfil our promise to the reader by laying before him the result of Mr. Bynoe's interesting observations on the Marsupiata, which the number of wallaby killed at Houtman's Abrolhos afforded him the means of perfecting. I may preface his remarks by stating, that all the information I could gain from the colonists on the subject was, that the young of the kangaroo were born on the nipple, which my own experience 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.
