452 PATHOGENIC BACTERIA. 



Czajrowski asserts that the bacillus can be cultivated 

 upon various albuminous media except gelatin and agar. 

 On glycerin agar-agar, especially with the addition of 

 hematogen, and on blood-serum, they should grow in 

 three or four days with an appearance like that of dew- 

 drops. Under the microscope the colonies are structure- 

 less. Mice die of a septicemia after a subcutaneous in- 

 oculation. 



An interesting field for experimentation has been 

 opened by Behla, 1 who seems to have successfully inocu- 

 lated a sucking-pig with measles by introducing some of 

 the nasal secretion from a case of measles into the nose, 

 which had been prepared to receive it by scratching with 

 a wire.
