PRESIDENTIAL ADDRESS. 155 
bald patches or partial depilation escaped my notice, but 
I certainly saw nothing resembling a pustular dermatitis. 
Later in the year two clinical forms of ringworm appeared 
in human beings, one consisting of angry, raised, circular, 
reddish patches of purulent dermatitis, the other the usual 
form of circular bald patches on hairy parts, or slightly 
raised circinate reddish areas on the face, ete. The former 
may possibly represent human infection with the mouse 
favus, but I have not, perhaps partly through faulty ob- 
servation on my part, or because such specimens were not 
eaught, seen in the mice patches of ringworm with stunted 
broken hairs, such as I have seen, in a mouse district, in a 
baby, dogs and a cat. As the evidence suggests in this latter 
instance mice as the conveyors of the infection, this form 
doubtless does occur in them. 
Favus.—Mouse favus is not uncommon in Australia. The 
first case described for this continent is one of my own? 
from Western Australia. We have met with it not infre- 
quently in this State, having received specimens from 
Lithgow (August, 1910—third mouse found infected), Gil- 
gandra (November, 1910), Cowra (February, 1918—mice 
suffering from this disease during the last two years; it 
apparently does not destroy them), and Coonabarabran 
(May, 1916). 
During the mouse visitation we had specimens from 
Narrabri (September), Tocumwal (November), and Barel- 
lan (HKebruary, 1918). In connection with the latter, an 
accompanying letter said that ‘‘two or three of this batch 
were suffering from a skin disease which seemed prevalent 
amongst them, and seemed to be the same as that which the 
men contract in handling wheat on affected stacks; we 
doubt if this disease carries them off.’’
