the publication of that gentleman's Tour across the 
Continent of America to the Pacific Ocean. In 1812, 
Mr. Nuttall, on bis return from a journey in those 
parts, brought seeds and specimens of this and another 
species to London; and baving by those means the 
living plants, I agreed with Mr. Nuttall to dedicate 
it to the memory of Dr. B. S. Barton, of Philadel- 
phia, our mutual friend ; under which name it was 
published in the Botanical Magazine, Since that pub-

veral pages of this work, with all the credit due to bis 
valuable discoveries, has found himself rather offend- 
ed at not having given him all the exclusive credit 
of discovery, which with justice and propriety to the 
memory of M. Lewis, Esq. I never could do.
