The extremity of the colon, or the rectum, passed between the bladder and 

 the uterus as usual. He dissected all these parts, and traced the bladder up to 

 the umbilical cord, where it lengthened into a pipe, and formed an open urachus. 

 It had not the pyriform shape of the common bladder. It was in making these 

 dissections of the kidney-liver, and those of the pelvis, that he divided the 

 principal vessels, mentioned below. All these intestines, and especially the 

 rectum, contained excrements of a light ash colour, but no meconium. The 

 bladder, though lengthened and continued by an urachus, as high as the navel, 

 opened in the usual place between the nymphae. The anus was imperforate, 

 and the rectum, immediately under the uterus, terminated in a blind pouch, 

 attached to some membranes that went to the anus. This pouch was quite full 

 of that sort of excrement just now described. 



Mr. le C. had confined himself, in the first examination, to the singularity of a 

 want of head, lungs, and heart, and of the existence of nerves, notwithstanding 

 these defects. In his 2d review, the next morning, the organs of the circulation 

 in such a production, which had lived nine months, raised his curiosity; but it 

 was rather too late for entire satisfaction, for he had not taken care enough to 

 preserve the internal parts, imagining before-hand that they resembled those of 

 two headless twins, in his possession, whose inside was entirely similar to that of 

 other foetuses. He discovered however the following things: — In the region of 

 the breast, the internal surface was lined with a membrane, which he took to be 

 a diaphragm thrust back and stuck to the pleura, because it arose from lumbar 

 muscular portions resembling the pillars of the diaphragm. Under this species 

 of midriff was a very regular distribution of arteries and nerves. 



In fig. 7, pi. 8, B is the lumbar region; c, those of the ossa ilia, and of the 

 pelvis; D, the umbilical cord passing through an opening across the teguments of 

 the lower belly, to be brought into view; e, the intestines; f, the aorta superior 

 before-mentioned; gh, the integuments of all the right side, opened on the back» 

 to preserve it whole, and also those of the belly ; they are thrust to the right side 

 to give a view within ; a a kind of single kidney, which occupied the place of the 

 liver. The principal part is covered by the intestines. It received several 

 small vessels from the aorta, but none of them was near so large as the emulgent; 

 b a small lobe, that might pass either for a small lobe of the liver, or for a capsula 

 renalis; d an orifice of a vein which was also ramified, through the kidney-liver,, 

 by branches as fine as those it received from the aorta. But this vein did not 

 terminate there; 1. It sent, upwards, branches to the muscles, to the vertebrae^ 

 and thence to the ribs; for, by blowing into the trunk, the air came out at the 

 origin of the uppermost rib he had dissected; 2. Below, it formed two large 

 iliac veins, g, which took the usual course; e the trunk cut, belonging to the 

 aorta inferior, of the length of a line; f tlie distribution of the rest of this aorta.
