Sunday, 26th. Squally weather, with rain. At 5 p.m. saw some sea Weed pass the Ship, and at 7 William Greenslade, Marine, either by Accident or design, went overboard and was Drowned. The following circumstances makes it appear as tho' it was done design'dly. He had been Centinel at the Steerage door between 12 and 4 o'clock, where he had taken part of a Seal Skin put under his charge, and which was found upon him. The other Marines thought themselves hurt by one of their party commiting a crime of this nature, and he being a raw young fellow, and, as very probable, made him resolve upon commiting this rash Action, for the Serjeant not being willing that it should pass over unknown to me, was about 7 o'clock going to bring him aft and have it inquired into, when he gave him the Slip between Decks, and was seen to go upon the Forecastle, and from that time was seen no more. I was neither made acquainted with the Theft or the Circumstances attending it, until the Man was gone. Wind, North-West to West; longitude 127 degrees 43 minutes West. Monday, 27th.

Between 10 and 11 a.m. took several Observations of the sun and moon; the mean result of them gave the Longitude of the Ship at Noon to be 127 degrees 38 minutes, and is 1 degree 49 minutes East of the Longitude given by the Log; but on the 4th Instant the ship by Observation was 47 minutes West of the Log, therefore she must have lost 2 degrees 36 minutes of the Log since the last Observation--an Error too great to be accounted for.
