It appeared to be a mixture of milk-sugar with pulverised 

 kephir grains. 



Mazoum. — This preparation, lately introduced from Armenia, 

 where it has been made for centuries, has somewhat the appear- 

 ance of clotted cream ; on warming, it separates into a liquid 

 whey and an insoluble curd.

There was no evidence of proteoses in the whey. 



Mazoum appears to have been produced by the lactic fermen- 

 tation of milk enriched with cream ; the sample examined was 

 very fresh and protein-hydrolytic fermentation was not appre- 

 ciable. 



An organism was separated from mazoum which gave colonies 

 rapidly spreading on the surface of gelatine to 1 cm. or more in 

 diameter, and which produced a slight putrid smell. This 

 organism, which was a bacillus, slowly peptonised milk without 

 curdling it, and finally transformed it into a semi-transparent 

 liquid jelly. 



Bulgarian Sour Milk. — This preparation is a thick gela- 

 tinous liquid of pleasant acid taste. It may contain as much 

 as 21 per cent, of lactic acid, and the proteins are hydrolised 

 to a considerable extent. The milk used for its preparation is 

 sometimes concentrated.
