No attempt was made to separate the milk albumen and 

 casein, as the samples had undergone some decomposition. 



It will be seen that the "fur" contains a much greater 

 proportion of albuminoids to lactose than is found in the 

 non-fatty solids of milk, whereas the non-fatty portion of the 

 "scale" contains less albuminoids and more milk-sugar than 

 the "fur," and more nearly approaches the composition of 

 non-fatty milk solids. 



As regards the effect of the separation of the "fur" upon 

 the composition of the "scald milk," the loss of Joz. of "fur" 

 of the above composition upon an operation dealing with 

 19 lb. of milk is much more than counterbalanced by the 

 evaporation of water during the operation, or even by the 

 proportionate increase of the percentage of non-fatty solids 

 owing to the removal of the fat alone. For example, in the 

 case of the results obtained with Pan No. 1 above, where 

 the loss by evaporation is SJ oz. and the loss by "fur " \ oz., 

 if the original milk contained 8*5 per cent, of non-fatty 

 solids, and taking into account the non-fatty solids removed 

 with the cream, the resulting "scald milk " would contain 8'8o 

 per cent, of non-fatty solids. 



There is, therefore, no danger of a charge arising for 

 deficiency owing to the separation of "fur" during the 

 operation of scalding.
