280 Prof. H. Rose on the Inorganic Constituents 



The milk was not skimmed, but evaporated at once and car- 

 bonized. 



Aqueous extract. — The washing required to be continued 

 for an extraordinary length of time. The residue of the eva- 

 porated extract consisted of — 



Chloride of potassium 4r42 



Chloride of sodium . 13*85 



Potash 29-66 y 



Phosphoric acid . . 7*25 

 Sulphuric acid . . . 0'17 

 Carbonic acid . . . 7*27 



or 



or 



100-06 



99-62 



Muriatic extract. — No evolution of carbonic acid could be 

 perceived on the addition of the muriatic acid. The consti- 

 tuents were — 



100-00 



Hence the muriatic acid had only dissolved phosphates. 

 Residuary carbonaceous mass. — It yielded — 



Potash . . ... 33-13 



Soda 9-01 



Lime 16-58 



Magnesia .... 3-40 



Peroxide of iron . . 1-10 



Phosphoric acid . . 36-60 



Silica 0-18 



100-00 



Thus the anoxidic portion of the milk, after oxidation, was 



of the same composition as the teleoxidic. 



The followinix are the results of the examination of the 

 o 



milk: — 



Extracted by water 34-17 



Extracted by muriatic acid 31-75 



Ash of the remaining carbonaceous mass . . . 34-08 



10000
