Composition of ITns-weetened Milk. — Unsweetened con- 

 densed milks are prepared in a similar manner, except that the 

 addition of sugar is omitted. 



The composition of this product is shown by the following

These milks have all been sterilised by heat. They have the 

 analytical chnracters of sterilised milk. 



Unsterilised condensed milk is also an article of commerce ; 

 Pearmain and Moor have found boric acid in a preparation of 

 this kind, which was sold for diluting and mixing with whole 

 milk. 



It is noticed that the totals of analyses of condensed milk 

 almost invariably add up distinctly below 100 per cent. ; it is 

 probable that the milk-sugar is underestimated. In condensed 

 milk the layer of solution which is attracted round the fat globules 

 by surface energy has probably a composition which is identical 

 with the composition of the liquid in which the globules are 

 suspended. When condensed milk is diluted with water it is 

 doubtful whether the liquid in this layer is diluted by the water,
