Tartarian Buckwheat (Polygonum tartaricum) from Hohen- 



heim. 



This variety diners from the common species, Polygonum 

 Fagopyrum, in that while the hulls of the latter are smooth, 

 those of the former are covered with folds and excrescences. 

 The whole grain, hull included, was pulverized and analysed. 

 10 grains weigh 0*2566 grm. *

II. 2*5924 grs. of substance dried at 100° C. gave 0*0597 

 gr. ashes.

IV. 0*3401 gr. gave 0*5710 gr. CO 2 and 0*1943 gr. HO. 



V. 0*5677 gr. gave 0*1407 gr. ammonio-chloride of plati- 

 num. 



VI. 5*0444 grs. of the same, by the method already de- 

 scribed, gave 1*1438 gr. woody fibre and combined inorganic 

 matter. 



VII. 0*7100 gr. of the woody-fibre gave 0*0006 gr. ashes.
