The sinus uro-genitalis and the rectumunite in a cloaca, or monotrematous sac, which, as in the birds, givesoutlet to the products of digestion, urination, and conception. I examined this animal on the 3d of April, 1847, and found sevenmarsupial embryons in the pouch, which, from their size, I have reasonto suppose must have come into the marsupium about the 10th ofMarch, as they compare with my specimens of the 7th of March. This figure represents the bladder, wombs, and sinus, inflated by theblowpipe. The wombs b b, when the animal is in rut, become twice ornearly thrice as large as they are in the figure; and the increasedmagnitude depends solely upon the development of the mucous tubuli, 190 PREGNANCY, Fig. of which M. Coste speaks in the above quotation. The cavity is veryminute—bean-shaped, and filled with an apparently slimy matter asin Fig. 52. In an opossum examined last winter, there being present Drs. and E. Wallace, the aorta was injected with size colored withvermilion. Much of the injection was found to be effused into thesmall bean-shaped cavity of the wombs b b; but there was a great multitude of tubuli standingFig. 52. vertically to the paries of the womb, that were filled withthe red injection, presentingthe appearance of waving, orst raight red lines, that passedfrom the inner superficies ofthe substance of the wombdown through the soft deci-duous matter to the innerboundary of it. The Fig. 52,gives a pretty correct view of the appearances presented upon cutting
