The author after more than eight years of study of the bacteriology of the respiratory tract, presents in this book some interesting conclusions as the result of his experience. The findings, if correct, would establish the etiology of all common colds on a bacterial basis. He even goes so far as to attempt to differentiate from the clinical symptoms the probable class or variety chiefly responsible for bacterial affections originating in or attacking the different regions of the respiratory tract, as the nasal, nasopharyngeal or the laryngeal portions. The author is a thorough bacteriologist and seems to be conservative in his conclusions.
Interesting features of his findings are that the predominating organism in the various respiratory affections changes with time, and more recent study of the bacteriology of the upper respiratory tract reveals great differences in the findings from those of five years previous.
