And that the Motion is communicated in the man- 
ner above fuppofed, is confirmed by the following 
Experiments : 
A Prop was fet againft the Back of the Cafe of 
No 2. to prevent its bearing againft the Rail^ and 
No I. was fet agoing; then obferving them for 
feveral Hours, I could not perceive the leaft Motion 
communicated to N° 2. I then fet both the Clocks 
a going, and they continued going feveral Days ; but 
I could not find they had any Influence upon each 
other. Inftead of the Prop againft the Back of the 
Cafe, I put Wedges under the Bottoms of both the 
Cafes, to prevent their bearing againft the Rail ; and 
ftuck a Piece of Wood between them, juft tight 
enough to fupport its own Weight. Then fetting 
No I. a going, I found the Influence fo much in- 
creafed, that N° 2. was fet a going in lefs than fix Mi- 
nutes, and No i. flopped in about fix Minutes after. 
In order to try what Difference would arife, if the 
Clocks were fixed on a more folid Floor, I placed 
them (exadlly in the fame manner as in the laft Ex- 
periment) upon the Stone Pavement under the Piazza's 
of the Royal Exchange, and ftuck the Piece of Wood 
between them, as before ; and fetting No i. a going, 
the only Difference I could perceive, was, that it 
was 1 5 Minutes before N° 2. was fet a going, and 
N° I. continued going near half an Hour before it 
flopped. From thefe Experiments I think it plainly 
appears, that the Pfcndulum which is put in Motion, 
as it moves towards either fide of the Cafe, makes 
the Preflure upon the Feet of the Cafe to be unequal, 
and, by its Weight, occafions a fmall Bearing or 
Motion in the Cafe on that Side towards which the
