          I find here quite common three species 
 of Alnus, viz. A. glutinosa W. [Alnus glutinosa Willdenow]
 [A.] incana W. [Alnus incana Willdenow]
 [A.] serrulata [Alnus serrulata]


 The first glutionosa [Alnus glutinosa] is  fine species. The specimens
 of adult leaves while drying give out a resinous
 or varnish-like substance, which causes the 
 specimens to adhere to the paper.


 At one time I had doubts that it might prove like
 [crossed out: a] Betula, but the difference of the fruit satisfied me
 of its agreement with the other species of this genus.


 Dr Gray's plates of Betula in the 2d Edition is beautifully 
 done, and the work admirable. It is indeed
 a masterly production, and worthy of a Harvard Professor.
 Do you find all three species of Alnus in the State 
 of New York? 


 Some 2 years ago , you promised me a copy of your
 Lectures on Botany, a lithographed work. Where is
 it?There was also a package of plants from
 Buckley* & I hope you have [added: them] safe. They were 
 never sent me, though you acknowledged them 
 at the time, and I could not come after them.


 Pray let me hear from you as early as convenient
 I hope to be a better correspondent on Botany though
 I fear I have not much that will interest you
 when your Flora is done. I hope to see you and Mrs Torrey
 and your Daughters and Son this fall. It is time I came to New
 New York and paid you a visit and renew my personal aquaintance [acquaintance]
