fo many more of the Silks it will break through in a 
given Space of Time*, whence the number of the 
Silks, which oppofe themfelves to the Motion of the 
Globe in a given Time, being reciprocally proportio- 
nal to the Effedt of each Silk upon the Globe, the 
Refinance made to the Globe by thefe Silks, or the 
lofs of Motion, the Globe undergoes by them in a 
given Time, will be always the fame. 
Now if the Tenacity of the Parts of Fluids ob.' 
ferves the fame Rule as the Cohefion of the Parts of 
thefe Silks, namely. That a certain Degree of force 
is required to feparatc and difunite the adhering 
Particles, the Refinance arifing from the Tenacity of 
Fluids mufl: obferve the fame Rule as the Refiftance of 
the Silks, and therefore in a given Time the lofs of 
Motion, a Body undergoes in a Fluid by the Tenacity 
of its Parts, will in all Degrees of Velocity be the 
fame ; or in fewer Words, that part of the Refiflance 
of Fluids, which arifes from the Cohefion, of theic 
Parts, will be Uniform.
