The 2 cases to be reported in this paper tell the story of a disease which eludes detection through the ordinary method of examination. Diagnosis, then, is difficult and often at fault. Afterward, when the physician knows beyond peradventure that he has to deal with a fungous infection, the applied therapeusis becomes relatively simple. The diagnosis can be arrived at only through laboratory technic, and the germicide usedmust be selective.
Since Micheli,1 1729, described Aspergillus and named it because of its resemblance to "rough head," mycologists have identified nearly four hundred species of the family.2
In 1842, Benet established its pathogenicity for man, and the pathologist Virchow demonstrated it in the lungs post mortem.
Siebenmann3 placed the proportion of aural infections due to Aspergillus at 1 per cent. The frequency of the infection in China earned for it the name of "Hong Kong ear." It is not uncommon in India
