Excerpt from Compend of General Pathology Chapter VI. Is based almost wholly upon a syllabus prepared by Prof. Jas. Ewing, of Cornell Medical College, for one of his classes, and my thanks are due him for permission to use it. I am indebted also to Dr. J. C. Johnston, of the same institution, for valuable hints and for the photographs which illustrate the chapter on neoplasms. The negatives for these and for Figs. 58, 77 and 78 were made by Dr. B. H. Buxton, of Cornell, and kindly loaned by him. The facts of pathology are common property, and the desire to aid the student should characterize every teacher and author; my hope in issuing this and the companion volume is that the facts have been so presented as to accomplish the object cited.
