My Dear Dr.

Your favour of the 24th has
just been received and in reply I
hasten to say - go on with the alteration
of the plates. It would be poor economy
to publish a known error - cost in such a
case is not to be taken into consideration
I do not think it would be just for you
to pay for any of the copies.

I had forgotten that you had informed
me of the arrival of the boy. The immediate
cause of Dr Foreman's letter was a message
from Bigelow asking whether the box had arrived.

The affair of Le Conte still hangs by the
eye lids. The Secretary has promised to drop me
a line as soon as this business has been attended
to.

I am off this afternoon on my way to
[crossed out: Bol] Phild [Philadelphia] stop at Baltimore one night -

I remain very truly
your friend & servant
Joseph Henry

Dr. Torrey
