This tree grows very slow, nnd the wood is hard, 

 compact, heavy and durable ; it is white outside, and 

 chocolate color in the centre, talking a very fine polish. 

 It may be used like Boxwood, and when stained of a 

 light yellow color, resembles it altogether. All kinds 

 of tools and instruments are made with it, also co^js 

 of wheels, teeth of harrows, spoons, &:c.

Locality — All over the United States, and almost 

 . in every soil, from Massachusetts to Louisiana, and 

 . from Florida to Missouri. Most abundant in swampy 

 and moist woods. 



Qualities— The bark o[ tlic root, stem and branches 

 is bitter, astringent and slightly aromatic. By analj-sis 

 it has been found to contain in different proportion 

 the same substances as Cinchona^ having more of Gum 

 mucilage, extractive and Gallic acid, and less of Re- 

 sin, Quinine, and Tannin. The Quinine of the Cor- 

 nus has been called Cornine, it has all the properties 

 ; of the genuine Sulphate of Quinine, but very little is 



afforded. The double distilled water o^ Cor mis is le- 

 mon color, that of Cinchona is reddish. 



The extract of Cor72us is less bitter and more as- 

 tringent than that of the best Cinchona^ but prefcra- 

 ble to the extract of the inferior kinds. 



This extract contains all the tonic properties, the 

 resin alone is merely stimulant. The bark of the root 

 is the stron2:cst : it is more soluble in water than Cm- 

 chona. The fresh bark frequently disagrees with the 

 stomach, and is improved by keeping at least one year. 



PROPERTIES— Tonic, astringent, antiseptic, co^ 

 roborant and stimulant. It is one of the best native
