The absorbents of the breasts of women and their glands are of im- mense importance in the practice of surgery. which always magnifies the contained object. from one of these injections, I had a drawing made as seen through a common magnifying glass; I have since had an engraving made, which I mean to publish im- mediately; how far I have succeeded, iiitnrc anatomists will judge. It is not always prope‘ to risk line prtparations of this kind to the event of drying. The quicksilver easily expands by greater heat, and often bursts its confines. "one is ali‘aid of this, the preparation, as soon as dissected, may be put into spirit of wine, allowed to remain there a week, after which it may be put into spirit of turpentine. The surrounding spirit of wine absorbs all its watery lluids ; the spirit of turpentine combines after- wards with the small portion oi~ spirit of wine imbibed by the gland, and the preparation then becomes transparent in the midst of a fluid. Prepa- rations of both kinds may be seen in the anatomical collection in Great Windmill-street, which I made fifteen years ago. The absorlvt'nts of the breasts of women form, like the arteries and veins, {an 5; one accompanying the external thoracics, and the other accom- panying the internal thoracics, or mammary arteries and veins. The oriental thoracic ubserlwz/s arise from the nipple, from the exte- rior part of the mamma, from the integuments, cellular membrane, and, as I have said, from the tubiili lat/{fern blood vessels, and even the nerves themselves; tics return upon themselves, and pass downwards. I have seen these glands The breasts in women, and the testicles in men, are more liable to cancer than any other glands. Why this should happen is perhaps difficult to say ; they are glands much connected with the general health of the body, and indicate the degree of vigour in the system pretty accurately in both sexes; even nurses and old women know this. They seldom are affected with cancer till the vigour ofthe system begins to decline, aiicrforty-five or forty-eight, when the menses generally stop in women, who naturally attri- bute this disease of the breast to the retention of the menses. They are, besides, glands more exposed than any other in the body, and often, from obvious reasons, more exhausted than they are able to bean-The cir- cumstance of their being more exposed, makes them liable to blows, and a greater number of accidents than any other glands, and from one or all of these causes they are frequently indisposed, and very often these com- plaints terminate in cancers.
