Obs. Few plants have undergone greater modifications, by cul- 

 ture, than this esculent herb ; and those varieties farthest removed 

 from the original form, are the most esteemed. Cabbage, in every 

 form, has always been a general favorite with the Germans; and 

 from them we have borrowed not only the preparations of the herb, 

 but their names, such as Bauer-kraut; and Kohl-Salfit, which 

 latter (meaning literally Cabbage Salad,') has been anglicised into 

 Cole and even Cold-Slaw!

Obs. This plant is pretty generally naturalized among us, but 

 not much cultivated. It makes a rather troublesome weed, when 

 fully introduced. In the West (especially in Ohio), it is extensively 

 cultivated. The value of its highly acrid seeds, in the hands of the 

 cook and physician as a condiment and rubefacient is well 

 known.
