A case of this kind Dr. Hunter attended. A woman was in labour, and could not be delivered in the natural way, from a tumor on the side of the pelvis preventing the child's head from coming down. After she was compleatly exhausted, and the pains gone, he was obliged todehver by the crochet, of the Glands ty' Mm Ausoitnsxis. are frequently enlarged and diseased. 137 " Grandes sunt, ct frequenter intu- mescunt." In the dead body otaman, whose left testicle had formerly been cxtirpated on account of its being cancerous, I found the lumber glands enlarged to the size of a child's head at birth, and inclosing the vena eava inferior, and aorta descendens, for some way. THE MESENTISRIC GLANDS. The child, of course, was lost; the mother fell into a fever and died. Haller, speaking of the same glands, says, "Funestis schirrls obnoxiae l" THE SACRAL GLANDS. HallCr blends these with the former Class. They are connected with them, undoubtedly; but, lying more in the hollow of the sacrum, and be- hind the rectum, I have considered them apart. Some of these are a conti- nuation of the glands of the mesocolon, and belong to the rectum; others to the vagina, bladder, and glutmi muscles. " In pelvi ultimas mesenteri- carum qua: rectum intestinum posteriores comitantur, hae sacra iterum ad- tingunt." These, as well as the former, are liable to sehirrus; and have sometimes so compressed the rectum, as almost entirely to prevent the ex- trusion ofthe faces: the patient has been worn out, and destroyed. THE LUMBAR GLANDS. Their number is from between a hundred and thir , to a hundred and forty or a hundred and lifty.--Ruysch makes them vastly more numerous than I do; and says, that he has counted seventy glands in a portion of the mesentery not broader than the palm of his hand-Hallcr does not say how many glands there are in the mesentcry, but uses the term plurimae. " In adipc circa vasorum intestinalium divisiones, plurima? glandular sedent, ovatae, compressaé, molles, tenera membrana obductzc, conglobati generis, cellulose: et ipsa; in mesenterio quidcm potissimum, tamcn etiam in meso- colo transverse, inque aliis mesocolis, etiam pone rectum intestinum.

This variety depends on this circum- stance-the intestinal canal is longer in some human bodies than in others; so much so, that it is sometimes seven or eight times the length of the whole body; at other times not more than three times that length. The number of the glands, and the breadth ofthe mesentery, are almost always in proportion to the length of the intestinal tube, and of course to the number of va inferior, are covered with aplexus of lymphatic glands, more numerous the absorbent vessels. As the absorbents are more numerous upon the jejunum, or superior part ofthe intestinal tube, their glands are not only more than any of the former classes. numerous, but larger, on that part of the inesentery which corresponds to The bodies of the lumbar vertebra; the lower part of the aorta, and ea- Under these the thoracic duct takes its ori- gin; so that I am not surprizcd at Bartholin's considering them to be the that intestine. real receptacle of the chyle in man. superior mesenteric artery. In the healthy state of the body, even in the adult, the largest glands on the mcsentery seldom exceed the size of an al- Haller says, " Cum vena cava, porro, anteriores glandulae dcscendunt, per lumborum vertehras, lumbalium no- rninc; celebres toties Bartholina laudatze, quas \‘ir cl. 0b numerosa immista x'asa lymphatica, omnino pro vero in hominc chyli receptaeulo, habuit."
