Needle, as near as I could, without letting the 
Needles touch. The refult was, that the floating 
Needle reded under the refpe&ive Poles of the o- 
ther Needle mark’d 
with the fmall Letters 
.r, n , s. So that by 
one Touch with the 
Loaddone, which gave 
the Needle a North- 
pole at N, where it 
was touch’d, it acquir’d 
three other Poles, j-, 
n. , s, which we may not 
therefore, improperly 
call its confequential Poles. Having difcover’d thefe 
confequential Poles, I made fome other Experiments 
to difcover more of the Nature of them, as they are 
defcrib’d in the Scheme annexed. The Needles were 
all of them two Inches long, made of the fame fine Steel - 
wire, and the Letters N, or w, and S, or j, denote 
the Character of North or South belonging to the 
points mark’d \ the great Letters fignifying the points 
the Loaddone was applied to, and the fmall. Letters 
dewing ..the xonfe.quentjaLPpks.^ .. -- 
There are two other Experiments defcribed in the 
fame Letter, relating to the Attraction ' of Fluids, 
one of which (viz. that of the Hyperbola, made by 
the Surface of the Water between two Glafs-planes ) '» 
being already defcribed in thefe TranfaBions (No. . 
3^6.) we fhall only tranfcribe the Account, givens 
of the other. y ; y 
I took feveral very thin pieces of Fir-board, and 
having hung them fuccefiively in a convenient man-
