Correction.— Mr. Ravenel wishes to correct an error which he 
inadvertently committed in his note on the Jerusalem artichoke 
^P- 55). and which we carelessly allowed to pass unobserved, and 
that was the classing of the sweet with the Irish potato as an under- 
ground stem. All reference to the sweet potato should, of course, be 
erased from the article.
