Middletown, Ct. Feb 20.1841

My Dear Sir,

Your favor of the 17th inst. has
just come to hand, and I hasten to reply.

As your letter was not received till evening, I cannot
get ready to leave on Monday, but if nothing unexpected
proceeds I shall hope to see you in your 
laboratory before the arrival of your leave for lecture on 
Tuesday evening. The apparatus may thus be put in 
order for exhibition on Wednesday; and if it will suit 
your convenience, I shall be happy to attend to it that
day, Providence permitting.If you have any desire to use
it further, I shall have no objection to leaving it [?]
with so kind and careful a friend.

Very Respectfully, yours etc.
John Johnston

Dr. John Torry
P.S. I have today just prepared an article on the 
proper construction and use of apparatus [added: for solid and acid] for Silliman's
Journal, which I presume will appear in the July No. this [?]
forthcoming being now about full. Perhaps it will not be thought
worthy to appear at all!

Prof. S accompanied by his son, has just gone to Boston
to commence next week his courses in chemistry-before, or rather,
in the "S. will Institute!"
P.S. I shall be under the [vicinity?] of returning Thursday.
