CEYPTOCOCCUS CEREVISIJE. 121 



Vogel, with Mycoderma Cerevisite, which grows on the surface of 

 Cryptococcus Cerevisia, and is a species of Leptomitus. 



Description. " Cryptococcus cellulis achromaticis, globosis aut 

 ovatis, corpusculo inferno (nucleus ?) hyalino notatis ; diam. ple- 

 rumque O007 interdum 0-005 0-003 mm. 



Variety. C. concatenata (Kiitzing). " Cellulis ellipticis vel ob- 

 longis in trichomata abbreviata ramosa concatenatis, corpusculis 

 internis interdum binis. 33 



It is found in yeast, diabetic urine, in the mouth, stomach, 

 oesophagus, &c. 



This parasitical plant is composed of round or oval cells, which 

 often present in their interior one or two little corpuscles, which 

 are more like globules of oil, or the nucleus of a cell, than a 

 vesicle. They are propagated by small projecting bodies on the 

 sides of the cells, w.hich, when they attain the size of the parent- 

 cells, give origin to new germs, and form a row of from three 

 to five elongated cells, but never a cylindrical stem. In the air 

 it immediately decomposes, on account of which it does not 

 fructify in the air as the Fungi. The presence of one or two 

 brilliant, strongly refractive globules in the interior of the cells, 

 and which are often regarded as globules of oil, is very charac- 

 teristic. Hannover and Vogel have not taken this circumstance 

 into consideration ; they have confounded the spores of various 

 species of Fungi with the cells of this Alga, and have falsely 

 supposed that all vegetable bodies with round or tubular forms 

 constituted an especial variety. 



Locality. This Cryptococcus is developed morbidly in the 

 secretions of the oesophagus, the stomach, or the intestines, or 

 is introduced into these situations by means of beer. Hannover 

 found it in the black fur of the tongue of persons labouring under 

 typhus; Lebert, in the mouth of a woman who had long pre- 

 viously suffered from disease of the womb ; Vogel, in faeces and 

 vomited matter; Robin, in the bitter fluid vomited by a woman 

 who, after fasting many weeks, ate some decomposing apples; 

 Gruby, in a woman who had for eight years laboured under hys- 

 teria, accompanied for four years with daily vomiting (the vomited 

 matter consisted entirely of an agglomeration of Cryptococcus , 

 with mucus, saliva, and the remains of the food as the Crypto- 

 coccus seems to have the power of developing itself on the inner 

 coat of the stomach in the same way as the Champignon du 

 Muguet in pharyngeal diphtherite) ; Bennett, in the vomited
