Gravimetric Determination. 



Dilute a measured portion of a 40 per cent solution with an 

 equal volume of water, use 5 c.c. of the diluted mixture, cor- 

 responding to 1 gram of the condensed milk and proceed as 

 directed under "Milk." 



Total Solids. 



Dilute a measured portion of a 40 per cent solution with an 

 equal volume of water, measure 5 c.c. of the diluted mixture, 

 corresponding to 1 gram of the condensed milk into an evap- 

 orating dish containing 15 to 20 grams of pure dry sand and 

 proceed as directed under "Milk." 



Ash. 



Ignite the total solids at very low redness, cool, and weigh. 

 See "Milk."
