Boston 16 April 1841

Dear sir
I had this morning the great
happiness to recieve your invaluable package. I shall
not attempt to express how it delighted me. Allow 
me to express to you my warmest acknowledgements
for the great kindness. Will Dr. Gray excuse me if
I do not at this time particularly acknowledge 
his very kind favours. But I am overwhelmed
with matters, for though we do not sail till to- 
morrow - everything must goon board in two hours.
I hope to make such use of the opportunities which
you and Dr. Gray have so generously furnished me with,
as to be of more service as a correspondant when I get
back. It is indeed a great thing to go thus provided:
and I feel more than I can say.
I will carefully attend to the parcels for the dis-
tinguished foreign gentlemen with wch you have entrusted
me. May it be granted me to see the illustrations of DeCandolle!
