1792. both in the foregoing journal and in my chart o f the coaft of New
tD r'i Albion, fouth-eaftward from that cape to this ftation.
The longitude, thus afcertained, is found to differ likewife from that
afligned to it by Sen'- Melafpina, 'who places Monterrey in 237° 51', and
who alfo places the north promontory of cape Mendocino, 26', and
point de los Reys, 33', further to the weftward o f their fituations (hewn
by our obfervations. By thefe calculations, the' whole o f the coaft of
North Weft America that we have yet vifited, is uniformly removed
to the eaftward o f the longitude afligned to it by Captain Cook and
Senr- Melafpina; authorities no doubt that demand the greateft refpecl
and confidence; yet, from the uninterrupted ferenity o f the weather
that prevailed at the time our obfervations were made, I have been
induced to adopt the meridian obtained from the refult o f our-own
obfervations, which, at noon on the 29th of december, fhewed Kendall’s
chronometer to be fall o f meantime at Greenwich, l* 32' 32" 14"'

The latitude, deduced from twenty-two meridional altitudes,
taken on both fides o f the arch of Mr. Ramfden’s
new circular inftrument, varying between 36° 35' 27",'
and 36° 36' 50", fhewed the mean colle&ively taken 36“ 36'. 20"
This moft excellent inftrument was ufed, both at Nootka and at this
place, for the purpofes it is intended to anfwer, in making ftt.ch obfervations
as we required; in doing which its excellence'Was’fully proved;
and Mr. Ramfden is deferving of great commendation for its accuracy;
and the eafe with which it is managed and kept in its adjuftments.

The variation of the magnetic needle in thirty fets of azimuths by
three compafles, differing from 9 to 15 degrees, gave the mean refult
12° 22', eaftwardly.'

The tides appeared to be irregular and o f little elevation; by their
general motion, they feemed to flow but once in twenty-four hours, and
it was high water about feven hours and a half after the moon pafled the
meridian; the rife and fall was. about fix feet at the fpring, and four feet
at the neap tides.
Thus conclude the tranfadlions o f the voyage, appertaining particularly
to the Difcovery, to the end o f the year 1792. The,two following
chapters will contain the fervices performed, and the information acquired,
by the officers under my command during the time o f our fer
paration.
