Dear Sir Accept my thanks for 
your late favor, which came to hand in 
due time. I was gratified to hear of your success 
in solidifying car. acid, though I of course 
know, in your [pressing?] hands, such would be 
the result. Under less pressing [?] arguments
than mine are just at the present time. I
should probably have visited N. York [previous?]
to this time, in the hope of witnessing one of your 
experiments.

My last letter was necessarily written in
a very hasty manner, and I found it did
not express clearly and precisely what I intended.
Had it done so, it would have been 
seen that my proposed  stopcock [crossed out: ?]
did not contain the radical defect you
supposed! The escape of the gas around the screw
of the valve shank was supposed to be prevented
in the same manner as in the one proposed
by Dr. Mitchell, as described in your last
and indeed my proposed stopcock differs from
his only in having a unical [?] to [?] valve
to stop the gas from escaping when it is
