Summary of Content: Comments briefly on a lecture Hanford gave. Discusses an account of a torpedo experiment he published in the Army and Navy Journal. Expresses his reluctance to have foreigners transmit information overseas. Mentions that he left out information about how the torpedo entered the water in deference to Commodore Jeffers of the Navy Department and Ordnance Office. Since the results were unfavorable, they may try more experiments and would like to keep the information quiet for now. Adds an autograph postscript at the bottom of page three where he discusses sketches and a record of the experiment. Addressed to Hanford, as Lieutenant, U. S. N., New York Navy Yard.
