In referring to a plea for the manufacture of common names in advance of their becoming common (page 94), we remarked that Dr. Gray was referred to in Mr. Robinson's letter as having furnished an illustrious example which he was merely following, and that if Dr. Gray had ever been led into that practice he was probably sorry by this time that he ever attempted it. In the last issue of Silliman's Journal, page 493, we read as fallows from Dr. Gray's pen :

"We have come to agree with De Candolle, in urging that while vernacular names, i. e. common names, are freely to be used in their place, they ought never to be made. A deliberately manufactured vernacular name is a contradiction and a counterfeit. Exceptions there may be where a generic name may be aptly translated, but these are few".
