10 PM. Lieut Edwin Flye joined the vessel
as Extv Offir[E3]
[E1] The text had "PM" with apparently an "(A)" above it.
[E2]This appears to be "J. Worden", similarly to the one for the 8AM entry. However, Worden was removed from the ship by 2PM. Possibly it could be "I. Newton" (the only other officer whose name could be confused with "J. Worden").
[E3] It is difficult to read the name of this person ("Lieut" appears to be "Leit") and the position.
