MILK. 



Solids. 



A small quantit}' of asbestose, sufficient to absorb two grams of 

 milk, is placed in a two and one-half inch watch-glass, deepest 

 form, lined with tinfoil. This is dried at 100° and together with its 

 cover and clamp, is weighed. About two grams of milk are then 

 run from a pipette on the asbestose and the whole weighed again, 

 dried for two hours at 100° C. cooled and finally weighed. First 

 weight subtracted from the last gives weight of soli Is.
