finking, and Paufe taken together. This is all which 
my Ihort Time would allow me to obferve ; many 
more things fhould have been taken notice of, as will 
appear from the Hypothefis propofed to explain thefe 
Phenomena. 
But before I enter upon explaining that Hypothefis, 
I muff remark what Difference or Agreement is to be 
found between this Account of the Fountain, and 
another publilhed in the Philof. tfranf. Numb. 204, 
p. 909, 910, in two Letters from Dr. Oliver to 
Walter Moyle, Efq;. The Doctor places it a Mile 
and half from Brixam : I fuppofe he means Brixam- 
Quay, which is more than a Mile off from the Town. 
He gives the Dimenfions of the Bafon a little differ- 
ent from mine, making the Surface of it thirty Foot 
fquare, whereas I make it thirty-fix Foot. He fays, 
that it ebbs and flows very often every Hour } which 
is certainly falfe, as appears both by common Report, 
and by my own Obfervation. When it once begins 
indeed to flow and ebb, it continues to do fo feveral 
times in an Hour } but then there is after this again a 
certain Space of Time, perhaps two Hours or more, 
when it runs with an equable Stream, without any the 
leaft Variation: And this is a particular Circumltance 
not obferved in any Spring whatfoever that I have 
heard of. When the Dodor firft faw it, viz. in 
July 1693, he fays that he judged the Flux and Re- 
flux, as he calls them, to be performed in about two 
Minutes : If he means two Minutes each, it agrees very 
well with my own Obfervations j but as he had neither 
Glafs nor Minute-Watch with him, this Obfervation 
cannot be depended on. When he faw it again, viz. in 
Auguft the fame Year, he judged it to flow flower than 
before ;
