Auguft, Weft; and, in like manner, the latitude was found to be
*• »— ' 28° 30' 1 i" North.
Mr. Varila informed us, that the true longitude was i8°3s'
30", from Paris, which is only 160 16' 30" from Greenwich;
• lefs than what our watch gave by 14' 30". But, far from looking
upon this as an error in the watch, I rather think it a confirmation
of its having gone w e ll; and that the longitude
by it may be nearer the rruth than any other. It is farther
confirmed by the lunar obfervations that we made in the
road, which gave 16“ 37' 10". Thofe made before we arrived,
and reduced to the road by the watch, gave 16°" 33'
30": and thofe made after we left it, and reduced back in
the fame manner, gave 16° 28'. The mean of the three is
16° 30' 40".
To reduce thefe feveral longitudes, and the latitude, to
the Pic of Teneriffe, one of the moft noted points of land
with Geographers (to obtain the true fituation of which, I
have entered into this particular difcuffion\ I had recourfe
to the bearing, and a few hours of the fhip’s run after leav-
— ing Santa Cruz road; and found it to be 12' 11" South of
the road, and 29' 30" of longitude Weft o f it. As the
bafe, which helped to determine this, was partly eftimated,
it is liable to fome error; but I think I cannot be much
miftaken. Dr. Maikelyne, in his Britijb Mariners Guide,
places the Pic in the latitude of 28° 12' 54". This, with the
bearing from the road, will give the difference of longitude
43', which confiderably exceeds the diftance they reckon
the Pic to be from Santa Cruz. I made the latitude o f the
Pic to be 28° 18' North. Upon that fuppofition, its longitude
will be as follows;
