the Clock in the Afternoon the Tide ran the fame way- 
he Saild, 3/7. That a S. by E. Moon makes High- Water 
on all that Coaft, the Flood coming. from the South- 
ward : hence it will follow, that that day it was High- 
water there about Eight in the Morning, and confequenr- 
ly Low- water about Two,, wherefore by Three the Tide 
of Flood was well made up, and it is plain that Ce/Sr 
went with it 5 and the Flood fetting to the Northward 
ihews that the open plain ftiore where he Landed was 
to the Northward of the Cliffs, and muft be in the. 
Downs 3 and this I take to be little lefs than Demon- 
ftratioa A fecond Argument is drawn from the Wind 
wherewith he fet out on his fecond Expedition, ©/a.- 
S. W. as appears by the words lent Africo profcclus, 
with which the Navigation of thofe times would hard- 
ly permit a Ship to Sail nearer the wind than eight Points, 
or a N. W. Courfe • which would ferve indeed to go 
into the Downs, but would by no means fetch the Low- 
land towards Dengynefs, which is much about Weft from 
Calais, and not more than W. N. W. from Boulogne, if 
it (hall be faid that that was the Tortus lews from which 
Cefar fet out. Whence I take it to be. evident that if 
Cefar was not bound more Northerly than the South- 
Foreland, he could not have thought the Africus or S,W. 
Wind proper for his paffage, which was then intended 
for the place where he firft Landed the year before.

Promontory of falis-Cliffs by the name of 9( Jmqv cLx&vi 
whence there is reafon to conjefhire, that the Portus 4ci- 
us was very near thereto, and that it was either Am-
