Nvhat fharp tafte, when clarified as before, with the white of 

 an egg< and then infpiflated, gave twelve ounces of fyrup, 

 which had a difagreeable faHne tafte,' and might be confidercd 

 rather as a vegetable extraft than a fyrup. 



4. Experimeiii made to obtain dry Sugar fro f/i Tutij/h JVbeat, 



To try how far it was poffible to obtain cryftallifed fugar 

 from this plant, a quantity of fyrup prepared from the young 

 ftalks, and another procured from the ears, were each dif- 

 folved by newly made lime-water, and then boiled (lowlvj 

 during which procefs a great deal of impurities were thrown 

 up. When the liquors were ftrained through a woollen 

 cloth, each of them was inCpiflated feparatcly to the con- 

 fiftence of thick fyrup, and fuflered to remain for eight 

 months in a glafs in a place moderately warm. At the end 

 pf that time I found fn)all cryftals of real fugar Ihot up in 

 them J but it was with great difficulty thev could be fepa- 

 rated from the fluid part, the quantity of which was far 

 greater. Each of the fyrups was therefore infpiffated, at a 

 gentle heat, to complete drynefs, and the dry mafs was then 

 digefted with fix parts of rectified fpirit of wine. The 

 liquor, llill warm, being fpeedily ftrained through a piece of 

 Jinen as the undiflblved flimy parts remained behind, real 

 futjar of a yellowifh colour cryftallifed from the fpirituous fo- 

 lution on cooling. The alcohol was now drawn off from the 

 remaining liquor, and more fugar was obtained from the re- 

 fiduum by flow evaporatioit. I procured in the whole from 

 the fyrup produced by the yo\mg ftalks, two ounces ; and 

 front that produced by the young ears, one and a half ounce 

 of fugar. 



By this it is fufiiciently proved that real fugar may be ob- 

 tained both from the young freih ftalks and from the young 

 pars of Turkifli wheat. The feparation of it, however, from 

 the gummy and other parts with which it is combined, is 

 attended with fo much difficulty, and the produce in general 

 is fo fmall, that a pound of raw fugar of this kind will not 

 coft lefs than a dollar; fo that, in an economical point of 

 view, no ?Ldvantagc can be c.\pe6tcd from the preparation of 

 fugar in this manner,
