when it is purified by a second crystallization. For taking 

 out spots in linen, the stained part is dipped in water, 

 sprinkled with a little of the salt powdered, then rubbed 

 on a pewter plate, after which the spot is washed out with 

 warm water. Dr. Beddoes informs us, that the leaves and 

 stalks wrapped up in a cabbage-leaf, and macerated in warm 

 ashes until reduced to a pulp, have been successfully applied 

 to scrofulous ulcers. This poultice should remain on the 

 sore for twenty-four- hours, and be repeated four times. 

 Afterwards the ulcer is to be dressed with a poultice made 

 of the roots of the Spireea Ulmaria, (which see,) bruised and 

 mixed up with the scum of sour buttermilk. There is no 

 doubt that some of the foreign species may be superior to 

 tliis in the same way. Twenty pounds of the leaves of our 

 Wood Sorrel, fresh, yield six pounds of juice, from which 

 two ounces, two drachms, and one scruple, of salt, have been 

 obtained. A variety is found, distinguished by being a less 

 plant, flowering later, and having purple flowers. It occurs 

 between Owram and Halifax in Yorkshire. Linneus observes, 

 that the leaflets of the Common Wood Sorrel are erect in wet, 

 and hang down in dry weather ; and Villars remarks, that it 

 has the leaves of Trefoil, the taste of Sorrel, and the flower 

 of Geranium; from which last genus Jussieu distinguishes 

 it by the number of the styles, the form of the capsule, and 

 manner of its opening, its straight corcle or heart, without 

 any perisperm or albumen. This plant is called Wood Sour, 

 Sour Trefoil, Stubwort, Sorrel du Bois, and Pain d'Coucou. 

 If the roots be planted in a moist shady border, they will 

 thrive and multiply, and, if kept clean from weeds, will 

 require no other care. If the seeds of the other sorts are 

 sown in an open border, the plants will rise freely ; and if 

 permitted to scatter, there will be a plentiful supply.

Oxybaphus ; a genus of the class Triandria, order Mono- 

 gynia. ESSENTIAL CHARACTER. Calix : five-cleft, bell- 

 shaped. Corolla: funnel-shaped. Nut: five-cornered, one- 

 seeded, surrounded by the unfolded permanent calix. 



The species (all natives of South America) are, 



1. Oxybaphus Viscosus ; Viscid Umbrella-wort. Downy 

 and viscid : leaves heart-shaped ; panicle racemose ; stamens 

 larger than the corolla. 



2. Oxybaphus Glabrifolius. Leaves heart-shaped, glau- 

 cous, smooth; panicle corymbose; flowers in terminal tufts; 

 stamens shorter than the corolla. 



3. Oxybaphus Ovatus. Hairy and viscid: leaves ovate; 

 flower-stalks terminal, forked; stem erect; stamens nearly 

 as long as the corolla. 



4. Oxybaphus Prostratus. Leaves ovate or heart-shaped,
