that of raw fugar. As my principal objeft was to be con-* 

 vinced of this by my own obfervation, I made the following 

 experiments : 



I fowed fur this purpofe^ in the funnner of the year 1796, 

 on a pretty good, but fomewhat niarfliy foil, a certain quan- 

 tity of Turkifli wheat. When the young plants were about 

 fix inches in height, the leaves, on being chewed, had a 

 fweetifli tarte, but the ftalks, particularly at the joints, had 

 a real faccharine tafle. Thefe young plants were cut clofe to 

 the ground, and, after they had been freed from the leaves 

 and dirt adhering to them, ten povmds of them were bruifed 

 in a ftone mortar, and the juice expreffed. This juicej 

 which weighed three pounds, and which had a fweet but 

 herbaceous tafte, was clarified with the white of an egg ; and 

 the liquor, which was now of a bright yellow wine colour. 

 and which had loft almoft entirely its unplcafant tafle, was 

 infpiffated to the confiftence of fyrup, eight ounces of wh:cli 

 would have afforded an agreeable fyrup fit for ufe. 



2. Examination qf the Ears ofTurhiJJj IVheali 



As the young ears of Turkifli wheat, when they ftre juft 

 beginning to be formed, have a very agreeable faccharine 

 tafte^ thefe al fa were fubjefted to examination. Ten pound?; 

 of them, freed from the furrotinding leaves, being bruifed 

 in a flone mortar, and then prcli'cd, gave four pounds of a- 

 milky juice, which could not be perfe6lly clariiied by the 

 white of an egg. When evaporated flowly to the confiftence 

 of fyrup, 1 obtained from the above quantity of juice nine 

 ounces of a brown well taftcd fvrup ; which, however, was 

 diftinguiflied by a greater abundance of flimy matter thait 

 the former.

 Period of GroiL'th. 



Twenty pounds of the ftalks of this plant at a niore ad- 

 vanced period of growth being chopped, were bruifed in a 

 flone mortar with a little water, and the juice was exprcfTcd.-
