« Wheel being counterpois’d by this Weight, the Power 
« which ads by drawing theUpng Rope N, ads for 
“ raifirig the Weight only. Tlie Experiment which 
was made with this Engine has confirm’d the Truth 
“ of this Problem, by comparing its EfFeds with thofe 
“ of a Crane, in which the Proportion of the Bignefs 
of the Axel to the Circumference of the Wheel, 
“ was tlleTame^as in my Machine : For it happen’d 
that in the Crane, a Weight of One hanging at a 
Rope going about the Wheel, drew up a Weight of 
Se ven, when 'it had one Half added to it to make it 
« preponderate, or give Motion to the Power: And 
“i when the Weight to be raised, and the Weight which 
“ ferv’d as a Power, were proportionably encfeas’d, 
there was alfo a Neceffity to encreafe the additional 
« Weight, which made the Power preponderate, in the 
“ fame Proportion: So that as if was requir’d to add 
one Half to the Power when the Weight was Seven • 
« • the Addition To the Power became One for a Four- 
teen Pound Weight, Two for a Twenty-eight Pound, 
«<Tour ^ for a Fifty-fix Pound, and fo on ; becaufe 
the Refinance from Fridion encreafes nearly in the 
^ faW Proportion that the Weights ate cncreas’d. 
^ivt tkis did not happeh-to my Engine, ‘in which one 
Quarter was always fuffiHent for the Draught (or 
tomalde the^ Power preponderate) not only when 
the Weight was^ Sevtn, but aifo when it was Four- 
“ teen Pound, Twenty-eight Pound;^ Fifty-hx Ponrid, 
whidPeyidently fhews,' thait this Engine ads 
'without Fridion;’’ 
y Thus far Monf. PerauJt, But however plaufible 
this Defeription may appear, a little Attention will 
fhew, that if this'’new Engine had no -Fridion, yet it is 
more
