    of the lungs in children during the next four years may be mentioned the names of Itufz, Rilliet, and Barthez, Rees and Seifert. Rufz pointed out a state of the lungs which he called carnification, and which he properly distin- guished from hepatization. Seifert, in 1837, alluded to a peculiar form of pneumonia, occurring in infantile bron- chitis. Rilliet and Barthez, in their essay on pneumonia published in 1838, describe a carnification which resem- bled that produced by compression in cases of pleuritic effusion, but which was not attended by effusion. None of these latter writers, however, seem to have perceived the relation of this peculiar carnification to the atelectasis of Jorg, nor do they seem to have contemplated the possibility of its arising from any other cause than inflammation. In 1844, Legendre and Bailly published their valuable researches on diseases of the lungs in children. They first applied to the study of these diseases a means of investigation as simple as it was in its results important, and which has, as Dr. West truly remarks, advanced the progress of knowledge in this department of pathology more than the writings of the ten previous years put together. The portions of lung affected with the so- called lobular pneumonia wTere found by them to be inflatable, the effect of the inflation being to restore to the portions affected their normal appearance and qualities. For the name “ lobular pneumonia ” they substituted the term “ etat foetalThey pointed out the difference which existed between the effects of inflation on the portions which exhibited the fatal conditions, and on those affected with true pneumonia, the inflation producing no effect on the latter, while it restored the former to their normal appearance and qualities. The anatomical character of this “ foetal condition ” they described as follows :—The
