The reviewer was somewhat disappointed after seeing the title of this book to find many of the discussions of ocular manifestations of internal disease to be inadequate. He was unable to find in the index a reference to "vitamins" or to "riboflavin." Night blindness is dealt with in a line which says it may be due to lack of vitamin A. The discussion of progressive exophthalmos in relation to thyroid disease is not really adequate nor is the discussion of the ocular changes associated with renal disease. It is the reviewer's impression that this book is the work of an ophthalmologist who has made a good effort to deal with the ocular phases of internal disease but who could perhaps profit by collaboration with a well trained internist.
