 Dear Doctor


 You were mistaken
 in supposing I had the 'Cholera' for
 a fortnight. It was only a week
 in all. And during that time I
 took but two doses of medicine.
 It was only one of these spring
 turns to which all are liable
 & on which cholera often lays
 hold as an occasion for invading
 that particular individual rather
 than another.


 Yesterday I sent
 off over 200 species (put up in
 two days) to Rev J. Blake, Cumberland
 Centre Maine. Of [many?]
 I sent a number of specimens.
 I had just begun my final improvement
 of my exchange system
 but had not time to take
 advantage of it. Hereafter I
 can first write all the labels
 on a package at one sitting
 & then lay it out. I intend
 to make also a package or pile
