          of Dr [Fonemans?] son and his own -
sickness -

Mrs Henry requests me to give
her kind regards to Mrs T. and her
thanks for the [cup?] which came
safely to Washington and apparently
gave much satisfaction.

I have as yet heard nothing from
the maker of the microscope since
I received the letter accepting the
offer I made him. Do you know
whether he is at work on the article
and when it may be expected to
be finished.

I have just published a set
of tables of occultations computed
by Downe's of Phild [Philadelphia] which appears
to find favour with the astronomers
and which is intended to facilitate
the determination of the Longitude of
places on the American continent.
It will be found of importance to
our officers in Mexico The corps of
Engineers and Topographers have
been supplied with copies and
I think we shall obtain a harvest
