On another occasion I found the cancer-cells em-bedded in and infiltrated throughout with minute cretaceous molecules(Fig. 360). In cancer, as in atheroma of arteries, the mineral is oftenassociated with the fatty degeneration. A Tubercular Exudation passesmore readily into cretaceous and calcareous transformation than eitherthe simple or cancerous forms. Indeed it may be said that the naturalmode of ai-resting the advance of tubercle is by converting it into mineral. Pig. 367. Fig 368. matter. I possess specimens of miliary as well as of infiltrated tubercle,arrested in all stages of their progress, by cretaceous transformation, inwhich case, on microscopic examination, it is seen to consist of mineralmasses associated with a few tubercle corpuscles, debris of the tissue inwhich it occurs, and occasionally a few crystals of cholesterine (Fig. 367).Mineral Degeneration of Morbid Growths.—Mineral deposition mayoccur in all kinds of morbid growths, but is most common in fibromaand cystoma. In enchondroma the tendency is to form bone. Thewhite fibrous tumors of the uterus, we have previously seen, mayundergo the osseous transformation (Fig. 282); but this is an occurrenceof extreme rarity. Far more commonly the centres of such growths arecomposed of amorphous mineral depositions (Fig. 368), which frequentlyincrease, and invade their whole substance, causing arrest of their have
