 Respected Sir,


 For all the valuable information
 contained in your letter of October 23rd you will
 be pleased to accept my most sincere and grateful
 acknowledgments. You will permit me to say merely
 in justice and not with a wish to flatter, that we regard
 your authority particularly in the cryptogamic department
 as the best and indeed almost the
 only authority this side of the Hudson: and
 we suspect there is none better on the other
 side. We therefore regard ourselves as peculiarly
 [fortunate?] in receiving so many valuable communications
 from you. As you still persist
 in saying that you desire me to send packages
 of plants as often as possible I have put
 up another to send by the bearer which is
 chiefly made up of cryptogamous plants
 and which I have collected the present season
 in the vicinity. It is probable there may be some
 species among these which Dr Cooley has already
 sent you: as I have not lately looked over his specimens.
 The numbers commence in this package where those in
 the last package terminated, beginning with No.
 205 and extending to No. 327. I feel that I have no
 claim upon you but if your patience is not quite
