Remarks.— "We are not aware, wiih one exce| lion, that the hypericums are used for 

 any other purpose than orndment. Some of them bear elegant flowers. The H. 

 i4woe?iw?n bears a splendid flower, of the richest golden yellow, it has been gathered 

 from the banks of our sfeams and transferred to gardens, andit is hardly surplissed by 

 any exotics, in its claims on the florists auention. 1h.e H. Fe'foralum an introduced 

 species, and which covers fields in thfi Northern and Middle Slates, has long enjoyed 

 considerable rojiUJation in the cure of diseases, but with the faculty we believe it is 

 pretty much abandoned, but still retains a place among ihe housewife's herbs. It is 

 astringent and possesses no doult, some of the properties of the turpentine. It is used 

 for burns and bruises, in pectoral complaints, jaundice, and as a vermiluge.
