“ It is a singular fact, that the various species of this family, among which are included the different white Butterflies of Europe; feed chiefly on such plants as are nourishing and salutary to the human body, such as the various sorts of cabbages, coleworts, turnips, &c., and in every foreign country where these white Butterflies have been found, plants of the same nutricious qualities, are sure to be discovered in the vicinity of their haunts. ”
