II. Chem\cal Experiments and Ohfervaiions on the Prepara~ 

 ik?z of Sugar from vegetable Produakns found in Europe. 

 By SicisMUND Frederick Heujibstadt. 



[Concluded from Page 113.] 



9- Experiments ivith the Beta vulgaris altlffima, 

 the Beta cicia ^\i\^\md^' of Jacquhi, in ordei- to procirre 

 Sugar fro7n it. 



This beet, like the former, is very common, fo ihat 

 both kinds are ufed in Thuringia, and other parts of Ger- 

 many, as food for the cattle. It is more juicy than the 

 former, and has an exceedingly fweet tafte. Thofe which 

 I employed for my experiments, grew at Schonberg, near 

 Berlin, on an eftate belonging to M. Noldechen, member of 

 the privy council. On clofe examination, a great difference 

 was obfcrved in them ; they were all covered on the outfide 

 with a red rind, but in the infidc fomc of them were totally^ 

 white; others confided of red and white rings, and fome of 

 them of light red and dark red rings ; many of them were 

 very thick and tuberous, and others were almoft as thin and 

 long as the red beet. Whether this arofe from their being 

 of different kinds, or from the difference of the foil in which 

 thev arew, I cannot determine. Thofe which I employed 

 for my experiments, had grown in the fame foil. 



I took 112 of thefe beets, which weighed 135 pounds, 

 and, having freed them from the tops and rind, grated them 

 down, and when a portion of the juice had flowed off fpon- 

 taneoufly, expofcd them to ftrong prcfTure. I obtained from 

 them twenty-four quarts of very fweet violet-coloured juice. 

 •In confequencc of what I had been taught by repeated expe- 

 rience, I firfl boiled it, without any addition, till a third part 

 only remained, and at the fame time a great quantity of 

 albumen was feparated from it. When the liquor had 

 cooled, it was drained through a piece of woollen cloth, 

 and being then mixed with twenty-four quarts of lime-r 

 water, was boiled for half an hour. At the end of that 

 period it appeared as a clear liquor of a wine-yellovv' colour, 



and
