 Germantown July 15th 1866


 Dr. J. Torrey, New York


 My dear Sir


 I have received with great pleasure your
 letter of 10th instant, covering your excellent
 photograph for the Philosophical Society. It
 was handed over the next day to the librarian,
 W. Lesley.


 You are happy to be able to work in your
 herbarium, even in your shirt-sleeves and easy
 [?], during these very hot days. To me the flies
 are still more troublesome than heat and I have
 to keep in such darkness [added : to get rid of them] that I can scarcely
 see what I write. (I hear thermometer 104 degrees)


 I left the city with my family, 3 weeks ago,
 for a cool Germantown mansion, kept as a
 summer boarding house. We are certainly better
 than in the city; but yet complaining very loud,
 as we have reason to do, when the thermometer is
 so high with scarcely a breath of air.


 Still, how happy you must be in the midst
