Thirdly, The Magnet, as fuppofe one of a Pound 
weight, that will take up or lufpend a piece of Iron of 
die like weight, and no more, (fuppofing it to be 
in every part of equal vertue) when feparated and broke 
into a number of fmall parts, (imagining them not to 
weigh above half a Grain each)and thc'C drefl:,and Arm'd 
according to Art, will then be capable to fufpend fifty, 
nay perhaps a hundred times more the weight of Iron a- 
mongfi: them nowfeparate, than they could when all of 
one Mafs ; which appears to me, that the Attradlive 
Quality of the Stone feems to be increas’d in Proportion 
as its Superficies is to its Biflk of Matter. 
So by the third Experiment, I found that the Quanti- 
ty of Matter, that was us’d to compofe one VelTel more 
than tlie other, fignify’d nothing to the Afcent of the 
Water, which feem’d wholly to, depend on the largcnels 
or the fmallnefs of their Cavities, as to the Jiefght it 
would arifeinthem; and as their Cavities are leifen’d, 
fo the Difprqportions of their inward Surfaces to their 
Cavities are increas’d. 
And as the Magnet, when feparated into the premen- 
tioned number of fmallParts,wiII attrad more than when 
united in one, and is no more than feparating or work- 
ing the prementiond thick Body of Glafs into 'a number 
of fmall Tubes, that is multiplying the Surfaces; the 
Water then would arife in each of them fmgly, as it 
would when all in one Body, its Cavity being the fame 
with the others; by which means, the quantity of Wa- 
ter afeending in them is augmented from the fame 
Quantity of Matter. 
To conclude : There feems to be fuch an agreeable- 
nefs of the Qualities or Difpofitions of one widi the o< 
ther, that I fee no reafbn why the Fads proceed not 
from one and the fame Caufe ; for as the inward Surfa- 
ces of the Tubes are made fmaller and fmaller, fo the 
Powei of their Attradion (*as is vifible by the higher
