 the fuller the better, at the end. This should be begun right off. 

 Let me hear soon from you on these matters. Mary joins in love to

NEW YORK, Sep. 9th, 1850. 

 MY DEAR SIR: 



I have been oscillating continually since we parted between this 

 place, Princeton, and Phil . 



Your letter of the 29th ult. was received by me at Princeton 

 just as I was on the point of getting into the hack for Phil d . I ex- 

 pected to return the same day, but was unavoidably detained until 

 the end of the week, several days after the time mentioned as that 

 of the decision of the Bank as to your note. As I heard nothing 

 farther from you on the subject, I concluded that you found no 

 difficulty in procuring an endorser. 



I have delayed writing to you a few days until I could give you 

 some definite information as to my movements. 



I concluded last Saturday to start immediately for Washington, 

 but am now called to Albany on some business of my own as well as 

 that of the Institution. I shall return this week and immediately 

 start for Washington and if no accident prevent, I shall be there on 

 the I 6th. 



My family will not return to Washington until the middle of 

 Oct. or perhaps the 1st of Nov. 



You have seen in the papers the account of the death of Prof. 

 Troost. This will perhaps give us some trouble relative to the publi- 

 cation of his paper particularly with reference to getting possession 

 of the specimens for the use of the engraver. I remain, 



Truly your friend, 



JOSEPH HENRY.
