          Packet David Brown. By my story in
 New York on Monday. I have lost the
 rate of the astronomical clock in the Hall
 it ran down on tuesdy at 12 o�clock
 I did not reach home until about
 one too late! I will endeavour to
 regain the time but have now very good
 instruments Mr Alexander has taken his
 sextant with him. I was anxiour to observe
 if nother else the exact duration of the
 eclipse at Princeton as this is an element
 of some importance to the astronomers
 however insignificance to the chemist
 or Natural Philosophes. Give my
 [?] to Mrs Torrey & Dr Gray


 In [Haste?] your
 Friend
