268 BACTERIOLOGY 



parency of gelatine cultures of the former, and the persistence 

 of capsules on most of the culture media. 



Bacillus capsulatus mucosus. At the Institute of Professor 

 Klemensiewicz in Graz, Fasching discovered, in crusts 

 removed from the naso-pharynx of a case in which this 

 cavity was diseased, a micro-organism with short and rather 

 thick rods lying singly or in pairs or fours in a common 

 enveloping capsule. The bacilli give up the dye under 

 Gram's process. It is easy to bring out the capsule 

 successfully as a delicate rose-tinted area by protracted 

 staining of the prepared cover-glass infuchsine, or by slightly 

 warming after covering it with the stain. The bacilli are 

 destitute of motility, and do not liquefy gelatine. On the 

 plate colonies develop which have the appearance of drops 

 of mucus of the size of pins' heads. In thrust-cultures 

 there forms a typical nail-like figure, with active generation 

 of gas, and upon agar and serum a thick moist creamy layer 

 develops. A moist, viscid, white coating occurs on potato. 

 Subcutaneous injection causes a genuine septicaemia in 

 white mice. Fasching also found this micro-organism in 

 the sputum of a phthisical patient. 



Vibrio nasalis. Both in the nasal mucus and in the 

 buccal cavity rods of considerable size are found which 

 possess no power of automatic motion, and are arranged as 

 vibrios. They were cultivated pure by Weibel. Gelatine 

 is not liquefied, and the growth on the plate leads very 

 slowly to the formation of round islets. In thrust-cultures 

 a delicate white streak develops along the thrust-canal, 

 resembling a string of mucus. The culture on agar is less 

 transparent and thicker, and spirilla are found in it which 

 show a large number of bends (over' thirty). No growth 

 takes place on potato. When treated by Gram's process 

 the spirilla lose their colour. 



Other nasal bacteria. Keimann isolated a great number
