Sugar from the Bul-Hooh ' 95 



I at the farae time wrote to my friend Darracq, preparer 

 general at the School of Mines, to reqiiefl his opinion of, it. 

 He fen t me notice that he wouitl accompany me to vifit it; 

 which \ye accordingly did, ajid I can verify the difcovery, 

 till vvc give a detailed memoir on the advantages or incon- 

 veniences likely to refiilt from it. 



'■' In the mean time, I think it my duty to fay, ift. That 

 it is fitiiatcd in a very deep ravine, and to'^ the fouth of a re- 

 doubt, known under the name of the redoubt of Hillot, 

 v/hich conmiands it by about 150 toifes at lead. 



" 2d, That the fulphur prefents ilfelf in two very diftinft 

 ftates. In the firft, it has for matrix fometimes earth cf 

 agnn' adi colour, which evidently ferments with acid;» 

 xvithout being converted into lime, and fometimes gypfum, at 

 the (ide of which the fidphur is found. In both thefc cafes it 

 is of a beautiful Jemnn yellow colour, and traufparent as glafs; 

 fometimes it is detached in blocks of feveral pounds, o'l- en- 

 veloped in a foiiaceous mixture, which we have not yet been 

 abJe to determine. In the la(t cafe, the fulphur 'is of the 

 colour of colophonium, and appears to have undergone an- 

 evident degree of fulion, whatever may have been the ajrent 

 tliat occafioned it. ^ 



"3d, If the matrix, which is very hard, be divided, it 

 emitij a very renfible bituminous odour/and the fraftures {how 

 geodes of different forts. Some contain only petroleum, and 

 others very curious cryftallizations. 



" 4th, This mine, diuing great heat,=, exhales fo ftrong 

 an odour, that the proprietor was obliired to cover it with 

 feveral feet of earth to flielter himfelf from it." 



SUGAn FROM THE BEET-UOOT. 



Doctor Achard has publillied, at Berlin, the refults of a 

 fecond trial, made on a large fcale, to extraA fugar from the 

 beet-root, under the direction of a commifhon appointed for 

 that puri)ofe by his Pruflian majefty. Ey thefe refults it ap- 

 pears that 1560 quintals of beet-root give 595^ pounds of 

 raw lugar ; 450 <]uintals of refufe, and 100 ounces of fyrup. 

 Thirty quintals of beel-root, cultivated according to the' pro- 

 cefs^ of Adiard, gave each fix pounds three ounces of raw 

 fugar. The refufe may be eniployed as colfee, or to difiill 

 fpirit; and is more prolltable for fcedin<r cattle than beets 

 ihenjlelves. The raw fugar may be refined for every pur- 

 pofc \yhatever. According to' a calculation made'bv the 

 coniniillion charged to examine this difcovery, it wiil'pro- 

 duce to I'aiflia an annual fuing, or rather an advanta-.^e, of 

 two millions and a half of rix-dullars.
