the Eaftward, in order to ftrike foundings over the Macclef- 1780. 
field Bank. This we effedled at eight in the evening of the t , 
16th, and found the depth of water to be fifty fathoms, Sunday 16. 
over a bottom of white fand and Ihells. This part of the 
Macclesfield fhoals we placed in latitude 15 0 5T, and longi¬ 
tude 114 0 20'; which agrees very exadlly with the pofition 
given in Mr. Dalrymple’s map, whofe general accuracy, if 
it flood in need of any fupport? w'as confirmed, in this in- 
flance, by a great number of lunar ohfervations, which we 
had an opportunity of making every day fince we left the 
Typa. The variation was found to be, in the forenoon, 
o° 39' Weft. 
On the 17th, we had heavy gales from the Eaft by North, Monday 17. 
with a rough tumbling fea, and the weather overcaft and 
boifterous. On the 18th, the wind ftill continued to blow Tuefday 18. 
ftrong, and the fea to run high, we altered our courfe to 
South Weft by South; and, at noon, being in latitude 12 0 34b 
longitude 112 0 , we began to fleer a point more to the Weft- 
ward for Pulo Sapata, which we faw on the 19th, at four Wednef. 19. 
in the afternoon, bearing North Weft by Weft, about four 
leagues diftant. This fmall, high, barren illand is called 
Sapata , from its refemblance of a fhoe. Our obfervations, 
compared with Mr. Bayly’s time-keeper, place it in latitude 
io° 4 7 North, longitude 109° 10" Eaft. The gale had, at this 
time, increafed with fuch violence, and the fea ran fo high, 
as to oblige us to clofe-reef the topfails. During the laft 
three days, the fhips had outrun their reckoning at the rate 
of twenty miles a day, and, as we could not attribute the 
whole of this to the effedls of a following fea, we imputed 
it in part to a current, which, according to my own calcu¬ 
lations, had fet forty-two miles to the South South Weft, 
between the noon of the 19th, and the noon of the 20th;
