          When I recd.[received] your draft I handed it over to Dr. Gray & requested
him him to attend to the money matters & I requested Mr. Bailey to
forward the bill for printing & I would be paid, but the
bill did not come down till to-day. I made a Mem. in
pencil of the amount of your draft & Dr. Gray, thinking this 
was safe, did not keep any himself. Finding the bill did not come
from West Point, he handed me $47.10, the balance of what remained
after paying Fell's bill & some small matters. Now I don;t feel
confident about my Memorandum [crossed out: ?] for the figures are not
very plain. Please turn to your account book & see if the
sum is correct. I am almost certain as to the dollars. I will
send Mr. Aspinwall the mone y & we can arrrange the business as
to the balance.

If you can trust e again after
this miserable management I will do better in futurw. Mr. Bailey
is very willing to work for the mere love of science. If the stones
are sent to him he will return them ready for the printer & they
can be used in New Haven if you have a lithographer there. At
West Point the price is $2 per 100 for printing, exclusive of the paper.
The paper will cost $7.50 per ream (480 sheets) each sheet being sufficient 
for 4 quarto impressions. Th eother expenses are trifling.

You enquired in one of your letters respecting the rotary electromagnetic

many persons have been led to believe that it will soon supercede
the steam engine! It is a mere modification of the "wiggler" invented
long ago by Prof. Henry & reinvented by several other persons some
