Papilionaceous plants are rarely noxious to the larger 

 tribes of animals, though some species of Galega in-

 of late been found violently emetic, and those of 

 Latkyrus sativus have been supposed at Florence to 

 soften the bones, and cause death ; we know of no 

 other similar instances in this Class, which is one of 

 the most abundant in valuable esculent plants. The
