| Abstract | Printed copy of a letter written on behalf of Dr. Maskelyne by his former assistant, John Hellins, in reply to a pamphlet authored by Mr. [Thomas] Mudge. Mudge submitted a chronometer of his own construction for a prize offered by the British Parliament for the determination of longitude at sea. During testing at the Royal Observatory the watch stopped working, leading to claims by Mudge that his device had been improperly handled by the observatory's director, Dr. [Nevil] Maskelyne. In the letter, Hellins details his observation of Maskelyne's great care in moving and winding chronometers. | ||
