The fresh sample contained 44.73% water and 5 5.23% dry 

 matter. 



There exist at least three different kinds of bacteria in 

 this product. The most numerous colonies on agar are of 

 two kinds. 



I. The largest colonies on bouillon agar show under the 

 microscope very large chain-like forms. It hardly liquifies 

 gelatin. Surface culture on agar : white, without lustre. Stab 

 culture in agar : much development on the surface, but very 

 little along the needle track ; no gas bubbles visible. On 

 potato : light brown, with minute foldings. In bouillon : kahm- 

 haut white and lustreless, breaking easily on shaking 



II. The second microbe forms small colonies on bouillon 

 agar. It readily liquifies gelatin producing thereby an acid 

 reaction. Stab culture in agar : developing along the track, 

 with chalk-like white colour and showing formations like the 

 Bac. mycoides. On potato : greyish, with irregular foldings. In 

 bouillon : developing on surface white and lustreless. Solution 

 remains clear. On shaking, the skin does not break and it sinks.
