mamma, while the second is suggestive of a carcinoma portio 
uteri. The former conforms in many ways with the type 
called by Kaufmann (Pathologische Anatomic, 1904) the 
combined infiltrating and nodular form; its tendency to 
remain in or around the fibrous sheaths of the bronchiole 
gives evidence of this. The tumor of the civet's lung is 
probably the nodular form of Kaufmann, since it has spread 
rapidly beyond the adventitia, and is attacking and filling 
up the alveoli.
