          which I haste to deliver. It was - that he, Mr. Lambert,
had found Pursh's Carices, and that they were at Dr. Gray's
service whenever he pleased to send for them. I am quite
sure I have gotten the message right, but it was given
me just at taking leave, and I cannit be certain about the
words. I have gone through with Clayton's lichens, + also with

Michaux's. The later's Umbilicaria pustulata is U. pennsylvanica! I
want to look at those of Walter's herb. (for he has gotten Cetraria
nivalis down in his Flora) if you can favour me with the address.
I understand Dr. Gray visited the family, and indeed he mentions it in
his Account of [?] Eur. Herbaria. Mr. Brown has gone by the way of Gib-
raltar to Marseilles + Florence to attend the Congress of Naturalists.
With my best thanks and respects to Dr. Gray, I am indeed sir
most respy + truly your Ed. Tuckerman
Dr. Torrey.
