ble by the presence of the alveolar epithelium. Those vesicles most affected 

 by the morbid process were crowded with embryonal corpuscles and detached 

 epithelium. In the more healthy air-cells, which had been moderately 

 inflated, some of the epithelia had become completely detached, and some 

 remained adherent to the alveolar wall. The epithelia, in many instances, 

 exhibited a coarsely granular appearance, and often contained two or more 

 nuclei, while others, again, had a nearly homogeneous, waxy-like appearance 

 and contained several concentric, circular striations and a faintly marked 

 nucleus. Some alveoli held, besides detached epithelia, a finely granulated, 

 albuminous exudate, in which were imbedded a varying number of inflamma- 

 tory corpuscles. Here and there was seen an alveolus, showing a delicate 

 reticulum of coagulated fibrine. The interstitial tissue, however, presented 

 the most marked and characteristic lesions ; it was greatly increased in quan- 

 tity, crowding upon and compressing the alveoli, and so filled with embryonic

The result of the examination in this case corresponds in the main, so far 

 as it goes, to the more extensive descriptions of these organs in syphilitic 

 infants, given by A. Gubler.* The microscopical appearances were essentially 

 the same as those given by Cornil and Ranvier t under the head of " Syphili- 

 tic Pneumonia and Syphilitic Hepatitis."
