THE BRITISH JOTJRNAL OF SURGERY
have never before seen in any text-book, a good description and a coloured illustration of a cannula in the sphenoidal sinus ostiuni as seen by the nasopharyngoscope. The remaining sections on the frontal sinus and ethmoid labyrinth deserve very high praise, they are not only up-to-date, but far in advance of most treatises on these subjects.
The pnnting 9s clear, and the illustrations are singularly apt and well executed.
Copious references are given throughout the text, well representative, espccially of American rhinology, but we think not quite so generous to British workers in the speciality as to German writers.
The author has aimed a t supplying his medical colleagues with a complete exposition of B relatively new field of special practice-a field in which the science of rhinology is constantly advancing, and therefore continually undergoing changes in views and practice, and if here and there we have ventured to criticize and t o note some omissions which appear to us regrettable, it is largely because this work, a monurncnt of industry and research, and reflecting the greatest credit on the writer, is so valuable and complete as a whole that it seems to challenge one to look for them.
