When Dr. Lewis asked me to write an introduction to or discussion of the two papers following, I was somewhat at a loss what to say. Dr. Garrett studied the tumors of the xanthoma group with all the angiomas and other benign connective-tissue tumors which had accumulated in my laboratory for the past thirty years, and his presentation is so thorough and so clear that he left very little to be said on the subject of the xanthoma and tumors which resemble it in the color effect.

Dr. David T. Smith, when he came to the laboratory as a third-year student, had already begun his investigation on pigment in tissues and tumors, and especially on the character of the melanin pigment in the well-known group of tumors, best designated as benign and malignant pigmented moles. Dr. Smith has continued his work on melanin and blood pigment in tumors.
