162 VEGETABLE PARASITES. 



Barensprung (' Deutsche ' Klinik/ No. 6, 1855) thinks he has 

 succeeded in curing the disease by using a lotion, with one grain 

 of corrosive sublimate to an ounce of water. It appears to me 

 very improbable that this remedy should prevent relapses without 

 epilation, since the principal indication consists in removing or 

 killing all fungi, even those found in the sheath of the hair. 

 Blisters remove the skin and the fungus superficially, but after 

 three or four weeks they spring up again. 



Gudden adds nothing to this, and yet the treatment does not 

 seem to be so difficult after the above indications, Let the outer 

 skin be destroyed or lifted off, which may be done by vesication 

 as well as by means of Helmerich's ointment (see Itch-mite), and 

 let every hair be taken out immediately before or after. No 

 doubt, it may even then not be possible to remove, at the same 

 time, the sheath of the hair, and it will become necessary to 

 apply, after epilation has been proceeded with, those anti-parasitic 

 lotions which have been recommended in other places. The skin 

 which is taken off is to be burned, and the clothes and linen dis- 

 infected by heat and steam.

It is interesting to compare with this the fungus mentioned by 

 Fuchs in his work on the ' Diseases of the Skin/ ii, p. 538, as 

 occurring in Alphis (white spots on the skin). B. Langenbeck 

 made a drawing of it, which was not published at the time, and 

 has probably been lost since.
