Bay, the waters pafs in, and out, according as the 
wind blew eaft or weft. 
The inhabitants allured me, that this phenome- 
non never happened but fometimes in winter ; and 
that the rain-water runs out of the lake, when it is 
full, even though the wind be weft. Now it may 
be concluded from thefe obfervations, that the winds 
contribute very much to the currents of the Medi- 
terranean Sea ; fince they appear to be the efficient 
caufe of thole I have defcribed. 
Obfervations at Marfeilles. 
It is obferved regularly at the port of Marfeilles, 
that, when the winds are to the fouth-welt, the 
waters are up ; that is, that the waters rife confidera- 
bly upon the Ihore, and the quay of the port : and 
that, when they are to the north -weft, the waters, on 
the contrary, are very low. This fecond daily ob- 
fervation concurs with the former to prove, that the 
winds may be the caufe of the currents. 
But as common matters are palled over with con- 
tempt, frequent obfervations, which may be very 
quick, are neglected, and people are more ready to 
attend to what is more lingular ; fuch as the extra- 
ordinary flow, that happened at the port of Marfeilles, 
on the 29th of June, 1725, when the waters rofe 
over the quay, and into the lb ops ; and as fuddenly 
retired. The philofophers of that place mention it.. 
But I did not fee it myfelf; but I lhall defcribe an 
inundation very like this, which happened at Bonne 
in Barbary-, which I law, on the fourth of the fame 
month, and the fame year.
