was not successful here, and carbolic and nitric acids were 
used, but successive growths in various parts of the body 
occurred during a space of some twelve months. Meantime 
the adults in the same family were one after another subject 
to the same attacks. In one case of a very obstinate nature 
only one spot, about one inch in diameter, appeared on the 
upper lip ; this was treated at once with carbolic acid, or 
benzol, and the cuticle in two or three days was renewed, 
and the spot had apparently disappeared. In a few days a 
ring, external to the one destroyed, began to show itself. 
This was again destroyed with carbolic acid, and then an 
irregular growth commenced, the ring, although interrupted, 
was yet easily seen in the position that the various patches 
occurred upon the face, nose, temples, and forehead, the 
hairs of the upper lip being the worst. 
Three names were given, by another authority, to the 
disease at this stage, viz. — favus, tinea circinatus, and tinea 
sycosis. It was at this stage that I made the microscopical 
examination of the hairs of the upper lip, and at the same 
time became aware of the unsatisfactory state of our know- 
ledge on this and kindred subjects. 
For a long time all my efforts were fruitless. I could 
neither get spores nor mycelium, nor anything giving indi- 
cations of what I sought. Having obtained some of the 
hairs shaved from the upper lip, and having washed these 
with absolute alcohol, then with benzol, and afterwards 
mounted them in balsam, mycelium chains became distinctly 
visible, clothing the diseased hairs very thickly. 
This was sufficient proof of the fungoid character of the 
parasite, but I wanted to see the spores also. 
Chancing to examine the alcohol with which the hairs 
had been washed, small transparent bodies were seen, which 
looked like spores. These, mounted in glycerin, changed 
their shape, appearing to swell out and lose their character, 
and in balsam becoming so transparent as to escape detection.
