e specific and infectious nature of cancer, that it is of extraneousnature, a something that attacks the body from without, and that itcan in no wise be due to deformity or misdirected growth of thenatural tissues. Such a method of inference is that of the weak orspecious logician who, having assumed his premises, proceeds to draw Fig. 119.—Growth in the Kidney resembling Cancer, (x 105.) Part of the region a in Fig. 118, more highly magnified, c is the fibrous capsule whichsurrounds the growth. To the left of this is the new growth, and to its right fibrous renaltissue, /is a fibroid Malpighian body, and about it is the fibrous renal tissue, showingmuch round-cell infiltration. In the new growth, d denotes a cauliflower excrescencewhich springs from the fibrous capsule, and e a loose shred of organized tissue, d and eare of similar structure, being composed of a central fibrous strand with columnar cellsset upon both sides. They much resemble some of the forms of epithelial cancer.

THE KIDNEY. 145 conclusions without stopping to ascertain that the premises, whichare the foundation of the structure, are correct. The theory is socomplicated, and involves so much that cannot be explained by thelaws governing the growth of vegetables, from which the simile of thefertile soil was derived, that one is warranted in declining to accept it.In the discussion of lesions of the blood-vessels it has already beenshown (Fig. 38) that growths are sometimes found in the walls ofvessels presenting some of the physical characteristics of cancer butwhich certainly were not cancerous, and attention was called to thefact that in the skin of infants the epithelial cells often arrange them-selves in whorls which are similar to the cell-nests of skin cancer.These two instances show that it is possible for the cells to arrangethemselves in such a way as to produce an imitation of cancer. It ismuch more reasonable to believe that the tumor in the kidney was theresult of misdirected cell-g
