 choice of Cow-itch, all those pods which are brown or shrivelled, 

 rusty, or of a bad colour or diminutive size, ought to be re- 

 jected. In medicine, the ripe pods are dipped in syrup, which 

 is again scraped off with a knife. When the syrup is rendered 

 as thick as honey by the hairs, it is fit for use. It acts mecha- 

 nically as an anthelmintic, occasions no uneasiness, and may be 

 safely taken from a tea-spoonfuU to a table-spoonfull in the 

 morning, fasting. The worms are said to appear with the second 

 or third dose. A vinous infusion of the pods (12 to a quart) 

 is said to be a certain remedy for the dropsy. A strong infusion 

 of the roots sweetened with honey is used in India bv the
