Motion of the Pendulum No I. gradually decreafing 
all the while, as the ocher increafed^ and in three 
Quarters of an Hour after, it flopped. I then left the 
Pendulum of No i. at Reft, and fet No 2. a going, 
making it deferibe an Arch of 50; it continued to 
vibrate lefs andlefs, till it deferibed but about 30 5 ia 
which Arch it continued to move all the time I ob- 
ferved it, which was feveral Hours. The Pendulum 
of No I. feemed but little affe(fled by the Motion of 
No 2. I tried thefe Experiments feveral times over, 
without finding any remarkable Difference. The 
freer the Room was from any Motion (as Peoples 
walking about in it, at^c.) I found the Experiments 
to fucceed the better; and once I found N®2. fet 
a going in 16' 20", and N° i. at that time flopped in 
3 6' 40". 
I fhall not offer my Opinion to this Honourable 
Society, concerning the Caufe of thefe "Phanom^ay 
or at leaft not till I have farther examined it by the 
Help of fomemore Obfervations and Experiments. 
VI. Further Obfervations and Experiments 
concerning the tnsjo Clocks above-mentioned^ 
by the Sanne. 
I N the preceding Paper I had the Pleafure to com- 
municate to this Honourable Society, an Ac- 
count of the extraordinary Influence I obferved two 
Clocks to have upon each other, and which was 
attended with fuch Circumftances, as I believe had . 
never before been taken Notice of. I fhall now beg
