Few faults are likely to be found in this treatise even by the most severe critic. However, in the preface the British author seems to imply that he was the original promotor of certain "new ideas, methods and modifications of established practice." In this connection, he refers to his advocacy of intravenous antitoxin for severe cases of diphtheria, a method which was used routinely by Dupaquier at the Charity Hospital in New Orleans as early as 1915 and strongly recommended by Mixsell of New York a few years later.
