and the middle of this Pulley was 7I inches from the 
middle of the fore-axis^ 
The lefler wheels being put on, and the firing being 
tied to the top of their axis, 
1. Three pound drew the modeli on the fmooth levell 
Table. 
2. Twenty pound drew the lefler wheels over a fqua- 
red rod J of an inch thick. 
3. Thirty pound drew them over a round rod a little 
more then half an inch thick. 
4. Thirty one pound drew them over a fquare rod 
half an inch thick. 
f. Twelve pound drew the hinder wheels over the big- 
ger fquare rod. 
The firing being laid under the axis, vi^ : | ofan inch 
lower then before. 
. 6. Twenty nine pound drew the leffer wheels over the 
bigger fquare rod. 
Then the 2 bigger wheels being put on inftead of the 
lefler^ and the firing lying over the axis, 
7. Three pound drew the modell on the Table. 
8. Twenty five pound drew the Fore- v^h eels over the 
round rod. 
9. Twenty five pound drew them over the bigger 
fquare rod. 
10. The firing lying under the axis, fixteen pound 
drew them over the leaft rod. 
I I. Twenty three pound drew them over the round 
rod. 
12. Twenty three pound drew them over the bigger 
fquare rod. 
13. Thirteen pound drew the hinder wheels over the 
bigger fquare rod. 
All thefe Experiments were tried twice at leaft, and 
moft of them i or 4 times over 
In all of them the Lead wqs laid exadlly upon the
