SOLIDIFIED MILK. 213 



facilitate the evaporation, by means of blowers and 

 other ingenious apparatus a current of air is established 

 between the covers of the pans and the solidifying 

 milk. Connected with the steam-engine is an arrange- 

 ment of stirrers, for agitating the milk slightly, while 

 evaporating, and so gently as not to churn it. In about 

 three hours the milk and sugar assumed a pasty con- 

 sistency, and delighted the palates of all present. By 

 constant manipulation and warming, it was reduced to 

 a rich, creamy-looking powder, then exposed to the air 

 to cool, weighed into parcels of a pound each, and by a 

 press, with the force of a ton or two, made to assume 

 the compact form of a tablet (the size of a small brick), 

 in which shape, covered with tin-foil, it is presented to 

 the public. 



" Some of the solidified milk which had been grated 

 and dissolved in water the previous evening was found 

 covered with a rich cream ; this, skimmed off, was soon 

 converted into excellent butter. Another solution was 

 speedily converted into wine-whey by a treatment pre- 

 cisely similar to that employed in using ordinary milk. 

 It fully equalled the expectations of all ; so that solidi- 

 fied milk will hereafter rank among the necessary 

 appendages to the sick room. In fine, this article makes 

 paps, custards, puddings, and cakes, equal to the best 

 milk ; and one may be sure it is an unadulterated article, 

 obtained from well-pastured cattle, and not the produce 

 of distillery slops ; neither can it be watered. For our 

 steamships, our packets, for those travelling by land or 

 by sea, for hotel purposes, or use in private families, 

 for young or old, we recommend it cordially as a sub- 

 stitute for fresh milk." 



A pound of this solidified milk, it is said, will make 

 five pints when dissolved in water. 



Another favorite form in which milk is used is that
