 My Dear Doctor


 Thanks for yours of the 12th & 
 the 16th. I was about to write you to
 say, that if you do not come on to see me,
 I may take advantage of a little vacation &
 have a day or two with you after the middle of 
 next week. Which shall it be? I can be
 absent only a few days. Jane went down 
 to Beverly to-day. She says she must attend
 to house cleaning & getting summer arrangements ready,
 and so cannot go with me. (Will come to N.Y. [New York]
 when the Exhibition is open.) She is a timid soul,
 and does not fancy sleeping in the house here when
 I am away. So I can stay only one night or two,
 if I come now. Had you not better come here.
 Just let me know this week.


 Dr. Bigelow has been blowing me up
 soundly for not citing him more in Pl. [Plantae]
 Wrightianae. You know how hard I tried 
 last winter to get sight of some of his plants.
 Wrote you [him?] over & over, but only got one or two.
 At length I concluded he probably did not wish
