make an agar-peptone medium with bouillon. On this medium, 

 stroked with serum, inenin^'ococci grew luxuriantly. A sub- 

 culture of the meningococci on the medium grew well. The re-

 logical Laboratory of the University. It made a suitable 

 medium for the culture of streptococci and other germs. Since 

 the beginning of the war, bacteriologists in Sydney have used 

 the stocks of German '' peptone " which still remain, and are 

 carefully husbanded. Locally made peptone can, therefore, be 

 prepared for bacteriological work.
