matter and sugar (Winckler 18:t9). Salts of iron do not alter thin 

 slices of it, tannic matters being absent. The presence of rnyrobiu, 

 which at present has been inferred rather than proved, ought to be 

 further investigated. The root dried at 100° afforded 11 -1.5 per cent of 

 ash to Mutschler (1878). 



Uses— An infusion or a distilled spirit of horse-radish is reputed 

 .stimulant, diaphoretic, and diuretic, but is not often employed. 



Substitute— In India the root o^ Morimja pterygospenna Giirtn. is 



considered a substitute for horse-radish. It yields by distillation an 



essential oil of disgusting odour which Broughton, who obtained it in 



minute quantity, has assured us is not identical with that of mustard or 

 of garlic.

 synonymous with Winter's Bark, and observes that it is common, 

 yet but little employed.
