These two volumes are outstanding with respect to their subject matter and the beauty of illustration. The contribution to clinical cystoscopy goes beyond the pattern set by previous authors and publishers. The completeness of the index and bibliography represents much effort in the selection of pertinent material, and little if anything of significance is omitted. It is only in recent years that such beauty and accuracy of illustration has been possible. Careful perusal of selected chapters leads one to the conclusion that no other publication affords as complete and accurate presentation of cystoscopic technic and diagnosis.
