Medical Education

I AM sorry Prof. Dakin (NATURE, February 3, p. 151) should think my letter (NATURE, January 13, P. 50) merely an attempt to open another discussion on evolution. I do not know how I could have expressed myself more clearly. Manifestly, a knowledge of such things as the anatomy of frogs and dog-fish cannot persist in the minds of medical students or be useful to them intellectually or professionally unless linked with other studies. They can be so linked only through truths about development, variation, heredity, and evolution. But here the naturalist is in conflict with the physiologists, psychologists, pathologists, and medical men into whose hands the students pass and whose opinions, abundantly supported by evidence, they always adopt.
