712 MEDICAL MYCOLOGY 



Isolated from cases of dacryocystitis. Not greatly pathogenic to rabbit. 



This organism is a strict aerobe. 



Colonies on agar deep, round, pinhead size, giving a grayish white uneven 

 surface to the culture. No growth on potato or serum. In broth there is a 

 deposit, yellowish or grayish white, in the bottom. Gelatin not liquefied.

Isolated from ulcers in the muzzles of rabbits. They spread to other or- 

 gans and are, eventually, fatal. Pathogenic to rabbit and mouse ; not to 

 guinea pig, dog, cat, hen, or pigeon. 



Hyphae 0.15-1.5 fx in diameter and are up to 100/x long. The organism is 

 gram-positive and a strict anaerobe; optimum temperature 37°, no growth 

 below 30° or above 40° C. 



On serum agar, only deep colonies appear. They are dull white, spherical, 

 very small. No development on potato. On serum, small, grayish white, finely 

 radiate, deep colonies. No growth in upper centimeter. In broth, there is a 

 slight development with uniform turbidity. Neither coagulated serum nor 

 gelatin liquefied. 



Schmorl's organism is reported by Sanfelice to be a Corynehacterium.

Found in the pus from a lesion near the navel. An account of patho- 

 genicity promised for a later paper. 



Hyphae 0.75-1.00/* in diameter, some irregular ones attaining 1.5/x. Strict 

 anaerobe, gram-positive, optimum temperature 37° C. 



On agar, colonies whitish gray, becoming darker, then yellowish, espe- 

 cially in the center. No growth on gelatin or potato. On coagulated serum,
