Experiment II. Figure 7 ,. 
Making ufe of the abovemention’d Machine, after I 
had balanc’d the Water and Lead in it, I fix’d to the 
End of the Beam B the Thread of the Plummet, which 
in tbe former Experiment I held in my Hj»nd. This 
added to the Weight hanging at B, and oblig’d me to 
put into the other Scale a Weight equal to n of the Lead, 
to recover the Mquilihrium. Then cutting the Thread 
or Hair, the Scale with the Weights overpois’d whilfl: the 
Lead was falling ; but the Equilibrium was reftor’d when 
it came to the Bottom. So that the Lead even then 
mull have loft only its Excefs of Weight above Water, 
Experiment III. Figure 8 . 
I tried the Way propofed by Monfieur Leibnitz in 
the following Manner. 
I took a Cork C weighing an Ounce, and fomething 
more than four times lighter than an equal Bulk of 
Water, and a Ball of Antimony fV about four times fpe- 
cifically heavier than Water, and of four Ounces Weiglit. 
The Cork laid upon the Water in the Veftel EAB D 
rais’d the Water from SS'^to 6G, and added an 
Ounce to the Weight of the whole Water: then fufpen- 
ding the Bali of Antimony by a String, and letting it 
hang in the Water at N, it rais’d the Water from 6 6 
to HHy and fo added another Ounce to the Weight 
of the Water. Then tying the Antimony to the Cork 
fSee the Figure of the Veftel mark’d with little' Letters) 
the Cork had added to it three Quarters of the Weight 
of the Antimony which the Hand before had fuftain’d, 
and made it fink fo as to be almoft cover’d, and raf- 
fed the Water to ik, adding three Ounces to its Weight. 
Hanging this Veftel of Water upon the Balance, and a
