 My Dear Doctor


 I have daily neglected, or
 rather postponed reply to your letter of 22nd Dec.
 expecting ever since 1st inst, to hear from you
 again, and to receive the specimens of plants 
 for Sprague to draw which you were to send.
 But as yet I hear nothing. I have been
 & still am extremely busy, or I should not have
 been stopped from writing ere this, to say how
 sorry we were to lose your Christmas visit.
 We did not give it up all at once, for you
 wrote as if you might come, after all.
 Dont fail us on the 1st March, & arrange
 to have time enough.


 We must talk over & arrange before I go
 abroad, which, if possible I must do in
 June or July.


 I am now so far along
 in my plans, at least, that I shall soon
 despatch a note  to the corporation to arrange
 & petiton for a year absence. If
 I get it well. If not I must be home
 by 1st March 1851.
 Oh how much I
 have to do, before I can go, because
