vin, a, 3 Dovey: Composition of Carabao's Milk 



153 



In determining the aldehyde figure, in every case after the 

 second end point had been obtained a further addition of for- 

 maldehyde was made and a third end point obtained, which thus 

 measured the acidity of the formalin in each estimation. The 

 total protein and albumin were estimated in the usual way. 

 Attempts to measure the albumin and casein separately by a 

 modification of the process used for the aldehyde figure did not 

 prove successful. The lactose was in every case estimated polar- 

 imetrically and checked by subtracting the sum of the fat, protein, 

 and ash from the total solids. 



The complete analyses of 19 authentic samples of pure cara- 

 bao's milk are given in Table III.
