d bore South 1/2 West,
distant about 5 leagues. Found the Variation of the Compass by an Azimuth
to be 17 degrees 50 minutes West. At 10 the Isles of Salvages bore West
by South 1/2 South, distance 2 leagues. I make those Islands to be in
latitude 30 degrees 11 minutes South, and South 16 degrees East, 58
leagues from Funchall, Madeira. Wind South-West; course South 35 degrees
30 minutes East; distance 73 miles; latitude 29 degrees 40 minutes North,
longitude 15 degrees 31 minutes West; at noon, Funchall North 21 degrees
West, 62 leagues.

Friday, 23rd. Light breezes and Clear weather. At 6 a.m. saw the Peak of
Teneriff bearing West by South 1/2 South, and the Grand Canaries South
1/2 West. The Variation of the Compass from 17 degrees 22 minutes to 16
degrees 30 minutes, Wind South-West, North-East; course South 26 degrees
West; distance 54 miles; latitude 28 degrees 51 minutes North, longitude
15 degrees 50 minutes West; at noon, Funchal North 12 degrees 45 minutes
West, 77 leagues.

Saturday, 24th. A fresh Breeze and Clear weather the most part of these
24 Hours. I take this to be the North-East Trade we have now got into. At
6 p.m. the North-East end of the Island of Teneriff West by North,
distance 3 or 4 Leagues. Off this North-East point lies some Rocks high
above the water. The highest is near the point, and very remarkable. By
our run from Yesterday at Noon this end of the Island must lie in the
latitude of 28 degrees 27 minutes and South 7 degrees 45 minutes East,
distance 83 leagues from Funchal, and South 18 degrees West, 98 miles
from the Salvages. At 1 a.m. the Peak of Teneriff bore West-North-West.
Found the Variation to be this morning 16 degrees 14 minutes West. The
Peak of Teneriff (from which I now take my departure) is a very high
Mountain upon the Island of the same name--one of the Canary Islands. Its
perpendicular higth from Actual Measurement is said to be 15,396 feet.*
(* The received height is 12,180 feet. Latitude 28 degrees 16 minutes
North, Longitude 16 degrees 38 minutes West.) It lies in the Latitude of
28 degrees 13 minutes North, and Longitude 16 degrees 32 minutes from
Greenwich. Its situation in this respect is allowed to be pretty well
determined. Wind North-East by East; latitude 27 degrees 10 minutes
North; at noon Peak of Teneriff North 18 degrees 45 minutes, 74 miles.

Sunday, 25th. A Steady Trade Wind and Clear Weather. The Variation by the
Amplitude this Evening was 14 degrees
