A FUNGOUS INFECTION OF THE EAR. 
The disease known as mycosis of the external ear of man is not 
uncommon. Cooke* describes as a new species, Aspergillus nigri- 
cans, which had been obtained from the human ear. Later heft 
again describes and also gives figures of this mou 
General descriptions of cases of mycosis of the external ear 
have appeared in various medical journals and books. One of 
more recent of these is by the noted specialist Ballengert, whose 
discussion may be here summarized as follows: The fungus forms 
inflammation with pains, itching and deafness. The mycelium 
may extend to the middle ear or even to the mastoid cells. 
The source of the infection is unknown. It is noted, however, 
that the disease is quite common among bakers and among the 
poor who are living in unsanitary conditions. It is stated that 
various species of fungi have been found growing in the ear, 
but the most common species are Aspergillus niger, A. flavus 
and A. fumigatus. 
In the treatment, a long list of antiseptic mixtures and powders 
have been used without general success. In fact, the fungus 
appears to thrive in spite of treatment with the ordinary solutions
