<c Sir Ifaac was of, that, in any cafe whatfoever, the 
<c equilibrium requires a gravity inverfedly propor- 
“ tional to the length of the columns, which pro- 
<c portion, as I hope to have evinced, is only demon- 
fbated in the cafe of homogeneity, and is not true 
<c in general. Thus, what I argued in the Phil. 
u Pranf. as;ainft Dr. Gregory, has alfo room againft 
u Sir Ifaac.” 
By all that I have faid, every body may judge, whe- 
ther differing from Sir Ifaac’s fentiments on a point, 
which I had for fo long a time examined, I did not ex- 
prefs my dilagreement with him in as decent a manner, 
as any one fhould, when fpeaking of fo great a man. 
And in cafe the Royal Society thought fome altera- 
tions were to be made in the form of my remarks, I 
declare, that I fhall execute it, as may be prefcribed 
to me by that illuftrious company. But I cannot 
help thinking, that, unlefs thofe, who would exa- 
mine my demonftrations, find fome error in them, 
no alteration is requifite to be made in my expref- 
.fions. I defire then either F. Frifius, or any geo- 
metrician, who thinks the queftion worth his exa- 
mination, to take the trouble of reviewing my calcu- 
lations, and to believe me ready to acknowlege my 
.error, when Ihewn to me by a candid and impartial 
examiner.
