 Friday evening.


 Dear Doctor


 I have concluded
 to hurry off my letter
 at last at a moments warning
 as I am now going down town
 & can add nothing tomorrow.
 I have gone over my Carices
 as far a C. aurea, but not
 thoroughly. I cannot satisy
 myself on them. I thank
 you for Tuckermans letter.
 You sent but one before.
