don to its Motion will likewife totally ceafe. and con- 
fequently the Globe’s Weight will catry it further 
down, unlefs the other part of the Opposition againil 
its Motion prevent it. But T (ay again, neither can 
this latter part of the Cppofition made to its Motion 
be ever great enough to flop the Globe ; for the 
Degree of this Oppofttion being reciprocally as the 
Velocity of the Globe, when the motion of the 
Globe is wholly taken away, it will become infinite- 
ly greater, than at any time, while the Globe is in 
Motion; fo that when the Globe fhould be ftopt by 
this part of the Oppofition made to its Motion, the 
Oppofition to the Globe’s Motion will become infinite- 
ly great h infomuch, that no Degree of force whatever 
could be able to impel the Globe further into the Sub- 
(lance, but this can never come to pafs. Befides, it 
is not neceffary to apply any fuch refined Argument 
againft this part of the Refinance ; it would be alone 
fufficient to confider, how unreafonable a Suppofition 
it is, that a Refiflance Ibould increafe, when the Ve- 
locity of the refifted Body decreafes. 
Thus may this Experiment be made ufe of to inva- 
lidate that very Opinion it is brought to fupport. 
But another ufe may likewife be made thereof: For it 
will ferve to illuflrate what the great Sir /fjtac Newton 
has more than once hinted, that the Refiflance of 
Fluids, which arifes from the Tenacity of their Parts, 
decreafes in a lets Proportion than the Velocity of the 
refifled Body decreafes (a); for as this Refiflance bears 
a great Analogy to the Refiflance of the yielding Sub- 
fiances we have been here treating of, fb we have 
found, that the Refiflance of thef' Subflances does
