to the human subject. In one case, according to Brown, seven 

 grooms were infected on the arms from a grey pony which was 

 suffering from the disease in an aggravated form. 



Fungus of fowl-scab. — Fowls are liable to a disease similar 

 to favus. According to Schiitz this disease is characterised by 

 greyish-white patches on the comb and w^attles of fowls, which may 

 extend over the neck and body. On nutrient gelatine a white 

 mycelium is formed ; and the gelatine is liquefied, and acquires a 

 reddish tint. The fungus can be readily cultivated on bread-paste, 

 agar-agar and potato. Cultures inoculated in fowls produce the 

 disease, but have no effect on mice and rabbits. 



Fungus of mouse-favus. — Mice suffer from a form of favus 

 which can be communicated to healthy mice by inoculation of scabs 

 or infected skin (Nicolaier). On nutrient agar the fungus forms a 

 thick mycelium, at first white, and later of a red or reddish-brown 

 colour. Mice can be infected with cultures. 



Mierosporon furfur This fungus occurs in Pityriasis 



versicolor. Grawitz regarded it as identical with Oidium lactis, and 

 it is very closely related. Cultivated on gelatine the jelly is hollowed 

 out and the mycelial growth sinks down, and is yellowish in colour. 

 ' Oidium albicans. — Vide Saccharomyces albicans. 



Aspergillus glaucus [Ewotium aspergillus glaucus). — Mycelium 

 at first whitish, becoming grey-green or yellow-green. Spores 

 grey-green, thick-walled. It is found on various substances, chiefly 

 cooked fruit, and is non-pathogenic. 



Aspergillus repens (Eurotium repens, De Bary). — Fruit-heads 

 fewer than in the above, which are at first pale and then blue-green 

 to dark-green in colour. Conidia mostly oval, smooth, colourless 

 or pale to grey-green. 



Aspergillus flavus. — Gold-yellow, greenish and brown tufts. 

 Fruit-heads round, yellow, olive-green or brown. Conidia round, 

 seldom oval, sulphur-yellow to brown in colour. Saprophytic in 

 man, pathogenic in rabbits. 



Aspergillus fumigatus; — Greenish, bluish or grey tufts. 

 Fruit-heads long and conical. Conidia round, and rarely oval, 

 smooth, mostly pale and colourless. This fungus occurs on bread, 

 and has been found in the human lungs, external auditory 

 meatus and middle ear, and in the lungs of birds. The spores 

 introduced into the vascvilar system of rabbits, or into the peritoneal 

 cavity, establish metastatic foci in the kidneys, liver, intestines, 

 lungs, muscles, and sometimes in the spleen, bones, lymphatic 

 glands, nervous system and skin.
