! A preparation composed of one part of oleate of copper, with four or five 
parts of lard,,is proving very useful in cases of ringworm, and is well 
worthy of further trial. In the accompanying picture A shows the filaments 
and the little round spores of Favus; B shows a hair invaded by the fungus 
of the common ringworm, the round spores of which are seen covering its 
surface; C shows the spores of the ringworm in filaments, and also more. 
highly magnified separately.

affection, characterised by the formation of rounded patches of little blebs. 
In ringworm, however, scales are found round the single hairs, or in patches
