This treatise on the physics and the physiology of the ear is a welcome contribution to our literature. It is couched in terms which make comprehensible obtuse mathematical language to the otologist. It clarifies the working of natural laws in physics and explains phenomena difficult to visualize. It renews interest in how we hear and how we maintain balance or equilibrium.
The author's approach to the problems concerned is somewhat revolutionary and, as he expects, will be met with opposition. Time for study and consideration of the ideas the author advances will have to elapse before his views and presently held theories and principles are reconciled.
