FMegmy and stringy milh shows its characteristics only some 

 time after milking. It is thick and of flat taste, and shows its 

 stringy consistency if it is observed while it runs from the finger 

 after immersion. It creams slowly, and it is difficult to obtain 

 butter from it, which, when obtained, has a disagreeable taste. 

 Investigations regai-ding this process are incomplete, but it seems 

 that it is produced by some process of fermentation. Phlegmy 

 milk is said to curdle sooner than normal milk, the curd presenting 

 likewise an abnormal appearance and phlegmy consistency. 



Such milk is said to infect normal milk. Its occurrence is caused 

 by indigestion, the use of poor and spoiled food, colds, and, accord- 

 ing to the latest investigations, also inefficient ventilation of the 

 dairies. 



In Norway, Sweden and Finland, an herb, Pinguicula vulgaris, 

 is added to the milk as a preservative. It is known to make milk 

 likewise stringy. 



Sandy milk i Sandy milk contains solid mineral granules, 

 which are often so large and occur in such quantities, that the teats 

 become clogged. 



Fuerstenberg, who examined such milks very thoroughly, distin- 

 guishes three kinds of milk stones or galactites. 



1. Real galactites consist of small granules, around which 

 amorphous salts of the alkaline earths have formed in concentric 

 layers. They are in shape globular, elongated, and occasionally 

 angular. Their surface is either smooth or rough, and their color 

 whitish to gray. In size they range from the size of a millet grain 

 to the size of a bean. 



2. PsEUDO GALACTITES are in appearance similar to the former ; 

 they consist, however, of a hollow and compact curd of casein, 

 which is covered with crusts of salt. 



3. CoNCREMENTs are amorphous, comparatively large, irregulai'ly 

 shaped masses of organic matter, without concentric structure. 

 Their surfaces are rough white and lustreless like chalk. "When 

 brought in water they swell and become soft. 



Ocmse : Food and water, rich in salts of the alkaline earths, es- 

 pecially lime.
