 intended to start on monday morning; but I made
 hime change his plans. We spent the whole day together
 and visited the Academy of Nat. [National] Sciences in the afternoon.
 I made him accquainted with some of our best
 men. On Sunday we were again good deal together.
 Monday was employed in a visit to our venerable Dr
 Darlington and, tuesday, my poor broken leg and
 the bad weather forbidding, I places him in the hands 
 of my friend J. P. James who accompanied him
 to Bartram's garden. He had a great desire to [assist?]
 to the meeting of the Academy; but the rain was
 pouring in such torrents that we had to remain at
 home, as everybody else. On Wednesday W. James
 overlooked his mosses and names them for him.
 He went away yesterday evening, having pretty
 well employed his time and promising to come
 and settle here or in Washington, next summer.
