CLARIFICATION OF MILK. 



161 



The Dctenninations of Others. — Bahlman' says the weight of material 

 deposited in the clarifier from 725 gallons of milk was 2| pounds. As an 

 average, then, 1 gallon of milk jdelded 1.6 grams of moist sludge (.044 per 

 cent.) equivalent to .6 gram (.01 per cent.) of dried material. 



In his "Studies on the Clarification of Milk," Hammer^ gives the follow- 

 ing amounts of slime secured from different lots of milk: • —

There has been contributed to this theme the experience of Mcln-
