678 EXPERIMENT STATIOIST RECORD. [Vol.35 



Dry milk or cream powder and a process for its manufacture, S. A. Vasey 

 and U. A. Cleeve (English Patents, 2772 {1915) ; 7766 (1915) ; ahs. in Jour. Soc. 

 Chem. Indus., 35 (1916), No. 11, pp. 649, 650).— "The particles of a milk or 

 cream powder are coated with a layer of an odorless, liquid hydrocarbon which 

 is nonvolatile at ordinary temperature (e. g., Paraffinum liquidum, B. P.) ; the 

 product will keep unaltered for a considerable period. Such a powder is pro- 

 duced by projecting milk powder by means of an air blast into an atomized 

 spray of the hydrocarbon, or by mixing the milk, or partially evaporated milk, 

 with the hydrocarbon and then drying the mixture. The finished product 

 should contain not more than 5 per cent of its weight of the hydrocarbon."
