My Dear Dr

Your favour of the 12th came
to hand at the beginning of the week but
I am sure you will excuse me
for not writing before when I inform
you that I have lectured 5 times this
week with recitations in the afternoon
besides being in Philad [Philadelphia]. on Monday

James Alexander left two weeks
ago for Virginia [?] before he had worked
out his time on account of a letter informing
him that his wife was unwell I took
the days for him in addition to my
other lectures -

The Berzelius
Battery is constituted as follows 
a cylinder of coak is formed by heating
in a furnace [pounded?] coak an [on?] stove
coal until the whole is cemented into a
mass In order to give it a proper shape

[left margin]
I went to Philad. [Philadelphia] to attend Baches 
[?] and also to
hear one of [Sycells?] lectures As a Lecturer he does not make
much impression but his matter is highly interesting to the
man of Science
