Starch forms the basis of the best "Violet Powder" 

 and kindred preparations, although Maize Starch 

 and Eice Starch are now much used for the same 

 piirpose. The British Pharmacopeia also recog-' 

 nises the two latter Starches as permissible for use 

 in medicinal preparations into which Starch enters. 

 The amount of flesh-forming material or albu- 

 minoids in the cereal grains generally ranges from 

 about 9 to 14 per cent.

 Hordeum vulgare. 



This cereal is very largely grown for brewing 

 into beer, although many other substances are 

 said now to enter into that useful beverage besides 

 malt and hops. Deprived of the husks it is 

 known as Pot Barley, and still further treated to 

 remove all the integuments and polish the grain 

 as Pearl Barley, which is used in soups and 

 puddings. Inferior or weather-stained barley, 

 which is unfit for malting purposes, is largely 

 used for making barley-meal used in feeding pigs 

 and other animals. 



The microscopical appearance of Barley 

 Starch is very similar to that of Wheat, but the 

 small granules are still smaller than in the latter, 

 while the large ones show concentric rings rather 

 more distinctly. 



Barley Starch is not met with in commerce 

 in the pure state, as is the case with Wheat Starch.
