made at Meyer & Kiemann's chemical factory in Hamburg 

 for application in creameries, containing 



Sol. iron sulf ate 63$ 



Iron oxide 17$ 



Chem. combined water 20$

 will be colored brown from the iron in the liquid. 



Chlorin Gas may be applied for deodorization as well 

 as for disinfection; potassium permanganate is however, 

 to be preferred, and does splendid service. If substances 

 possessing bad odor or taste are dipped into a weak solution 

 of permanganate they will be freed from these undesirable 

 qualities. The substance is entirely harmless, but is un- 

 fortunately comparatively expensive. 



Water for Factory Purposes. As is apparent from the 

 preceding, water plays an important part in the manage- 

 ment of the dairy business, and it may therefore be in 

 order to further explain the conditions which influence its 

 quality. 



If sufficient quantities of spring-water or good well- 

 water are at hand it is comparatively easy to keep the
