ANNALS OF THE 
considered as of a parasitic origin, have recently been shown by clinical observa- 
tion to be identical, and capable of merging one into another by imperceptible 
gradations ; thus establishing the fact which I had asserted from experimental en- 
quiry and the development of the parasites. 
In conclusion, a word or two as to the treatment of this class of diseases may 
not be out of place. 
The primary consideration will at once suggest itself, that since the fungi can 
only attack an enfeebled system, it is essential for the cure of the disease that the 
general health be restored by treatment appropriate for that purpose ; for we can- 
not expect a successful result while this important cause is still in operation. 
The remedies which have attained celebrity as specifics, have little claim to 
be so considered, since if we except arsenic, which by the way is only useful when 
it is pushed to a dangerous extreme, they are all of but little value. 
Of the topical applications I may observe, that my own experience of them is, 
that they are either inefficient or dirty, or both. The one to which I trust almost 
solely, has this to recommend it, that it is neither. 
Its action is founded on what ought to be our guiding principle in the treat- 
ment of these cases, viz., the destruction of the parasite ; and this, from extended 
observation, I believe to be effected by the Tincture of Iodine, far better than by 
any mineral or other agent we can employ, at the same time its application is unat- 
tended by any inconvenience. 
It is simply an alcoholic solution of Iodine, thus: Take of Iodine, 1 drachm ; 
Iodide of Potassium, half a drachm ; Alcohol, one ounce ; solve. Paint the diseased 
parts every day or on alternate days ; omitting it for a day or two if the skin be- 
comes sore, then resume it, and continue the application until the disease has dis- 
appeared. 
As yet I have met with no case which has resisted steady treatment of this 
kind, neither do I believe that I am likely to do so.
