Mr. Petiver turned the specimens over to Dr. Leonard Plunkenet, who "figured" them in his Phytographia, and sent Dickinson a new supply of brown paper, a copy of Dr. Plunkenet's Herball, a catalogue of Barbados plants (for comparison with those found in the Bermudas), instructions for collecting and preserving further specimens, and a plea for additional correspondents in America. Thus began an exchange which continued for nearly a decade, although, in spite of Petiver's importunities, Mr. Dickinson did not dispatch either large or frequent shipments of specimens. The correspondence appears to be incomplete, but what remains records only three more shipments received by Mr. Petiver to 1701. (313)
