for which reafon they advifed, that in cafe it did not 
flow and ebb when we were both prefent, one of us 
fhould abfent himfelf, to try whether it would do fo 
in the Prefence of the other. 
Upon our Return to it, the Man, who was ftill 
at work, told us, that it began to flow and ebb about 
half an Hour after we went away, and had done fo 
ten or twelve times. In lefs than a Minute, we faw the 
Stream coming into the Bafon, and likewifethe others on 
the outfide of the Bafon, begin to increafe and to flow 
with great Violence j upon which the Surface of the 
Water in the Bafon rofe an Inch and a quarter per- 
pendicularly, in near the Space of two Minutes ; 
Immediately after which, the Stream began to abate 
again to its ordinarv Courfe j and in near two Minutes 
time the Surface Was funk down to its ufual Height, 
where it remained near two Minutes more. Then it 
began to flow again as before ; and in the Space of 
twenty-fix Minutes flow’d and ebb’d five times s - So 
that an Increafe, Decreafe and Paufe, taken to- 
gether, were made in about five Minutes, or a 
little more. 
I could obferve by the Mark upon the Stones, that 
the Surface of the Water in the Bafon had rofe before 
we came at leaf! three Quarters of an Inch perpendi- 
cularly higher than when we faw it ; and I thought 
that I could .perceive fome very little Abatement each 
Turn, both in the Height, and in the Time of the 
rifing of the Surface, and confequently in the Time 
of its finking ; but the Time of the Paufe, or Hand- 
ing of the Surface at its ufual Height, or equable 
running of the Stream, w as lengthened } yet fo, as 
to leave fome Abatement in the time of the rifing, 
finking, »
