Variola inoculata in the Philippine monkey (M. cynomologus). Lesion at 
the site of inoculation on the trachea. Well-marked, tongue-like pro- 
jections of the epithelium due to swelling and proliferation of the epi- 
thelial cells. This stage proceeds one in which the surface becomes 
denuded of epithelium. Duration 6 days. 
. Variola inoculata in the Philippine monkey (M. cynomologus). Variolous 
lesions in the bronchus and in the lung following inoculation of the 
trachea. Variolous bronchitis and variolous pneumonia. Duration 6 
days. 
Puiate VII. 
Variola inoculata in the Philippine monkey (M. cynomologus). Proto- 
plasmic phase of Cytoryctes variole in the epithelial cells of the alveoli 
of the lung in a variolous pneumonia. 
. Variola inoculata in the Philippine monkey (M. cynomologus). Proto- 
plasmic forms of Cytoryctes variole in the epithelial cells of the seminal
