Mustard Gas and Its Implications.

The Medical Annual, 1940. Bristol: John Wright & Sons, Ltd. Price 20s. The Medical Annual in its 58th year of life maintains the high standard set in previous editions. It is an indispensable book for the busy general practitioner and contains much of interest. The ophthalmic section is by Sir Stewart Duke-Elder, who discusses such subjects as cataract and vitamins, diseases of the cornea, sulphanilamide in ophthalmology, affections of the iris, and optic atrophy. Among other contributions may be noted the medical aspects of flying by Group-Captain Rook and thyroid surgery, by Leonard Rogers. The latter deals with cases of extreme exophthalmos and reproduces illustrations from papers by Naffziger. The illustrations, some of which are in colour, have been well chosen and reproduced. Printing, paper, etc., are excellent.
