Dear Sir

Dr Barratt favored me with a reading
of you letter to him a few days ago. Your improvement
in the valve for the [C with 2 superimposed dots] soldifying apparatus is exceedingly
gratifying. I am inclined to think the valve
must be better than [added: the] old one, being so much more
simple in its construction, independent of the fact
that it must so admirably obviate the difficulty
we had to contend with before. I soon expect a short
article of mine on the general subject will appear
in the July No. Prof. Sil. Journal, and I think it
may be worth while to add a postscript giving
a description of the improvement, and the difficulty
it is particularly designed to obviate. Would you
have any objection to such a course?

Can you give me any suggestions from which I
may profit with regard to publishing a second edition
of my chemistry? A large part of the edition printed
has been disposed of, and I intend soon to commence
preparation for a second. I should be glad
to have it published in New York, if some responsible
publisher could be found who would like to take
hold of it. My intention is to enlarge it about
