ON THE 



COMPOSITION AND NUTEITIVE PROPERTIES 

 OF MANGOLD PULP. 



IN beet-root distilleries a refuse is obtained, known by the 

 name of Mangold-pulp. According to the method of Leplay, 

 the fermentation is carried on in the sliced roots, and the spirit 

 is separated by superheated steam passed through the mass in 

 closed vessels. The residual matter left in the stills after the 

 process of distillation is completed, is thrown aside in heaps, and 

 the excess of water allowed to drain off, after which it constitutes 

 the mangold-pulp. 



The material from which the subjoined analyses were made 

 was obtained from a mangold-root distillery which was established 

 a few years ago at Minety, in Wiltshire, a village about eight 

 miles from Cirencester. This distillery was erected by a com- 

 pany, formed under the Limited Liability Act, which is no 

 longer in being. After a brief period of existence the company 

 were obliged to wind up their affairs, the undertaking having 

 proved a complete failure. 



The method adopted by the company was that of Leplay, 

 which method, I believe, has been entirely superseded in France 

 by that of Champonnois. I examined at different times two 

 samples of mangold-pulp, differing, as will be seen by the ana- 

 lytical results, chiefly in the amount of water which they con- 

 tained respectively. The first sample, on analysis, gave the fol- 

 lowing results :
