Amongst the infectious forms of keratitis, the infection with the 

 mould fungi ' keratomycosis ' merits a consideration quite apart. 1 



Leber's excellent researches have shown that when a rabbit's cornea 

 is infected with the spores of the Aspergillusfumigatus, a necrosis occurs 

 around the site of inoculation, and at its periphery a dense infiltration 

 ring is formed. The necrotic mass of tissue riddled with the mould is 

 then cast off in toto, like a sequestrum. 



Those observers who have recorded cases in human beings (Leber, 

 Fuchs, Uhthoff, Axenfeld, Schirmer, Markow, Basso, Collomb, Gen- 

 tili, Ball, Wicherkiewicz, Kayser, Ellet, Johnson, Buchanan, Oster- 

 roth, Martin, Zade) agree that the strange-looking, dry, slightly 

 prominent, diseased area is separated from the surrounding tissue by 

 a demarcation ring, and is slowly cast off. (In the differential diag- 

 nosis it should be noted that Martin, in the A. f. A., 1905, li., p. 141,
