This volume is a decided improvement over the first atlas issued by the author in 1910. It is profusely illustrated with natural color plates illustrating all of the more common diseases that can be diagnosed by the use of the anoscope, the proctoscope and the sigmoidoscope. Methods of examination and pathologic reports are described in the text in contrast to normal observations. It is unfortunate that such a beautiful work is not thought worthy of a better binding.
