Point, and yet the whole Rod will continue to be 
electrical ; but, on putting the Sphere again into 
Motion, the Effluvia will become vifible as before, 
and will increafe,as the Sphere is more ftrongly excited. 
- Again, the Light will be vifible to a greater or lefs 
Difiance, as the Point is more or lefs acute; and as 
this Light is always brighteft next the Point, and 
grows fainter, as the Rays diverge, this is plainly 
owing to the different Denfity of the Rays at equal 
Diftances ; for, when the Point is more acute, the 
Rays will diverge lefs, and therefore will be denfer to 
a greater Diftance than when it is lefs acute. 
When a Non electric, whole End is flat, is brought 
within a few Inches of the Point of the electrified 
Rod, the electric Stream will be attracted by it, 
and the Rays made to diverge lefs than before ; and 
the Effect will be the fame as if the Point was 
more acute ; viz. a Continuation of the Light to 
a greater Diftance, and which will be farther in- 
creafed by the additional Velocity the Particles will 
acquire from the Attraction of the Non-electric. 
What will follow on a nearer Approach of the Non- 
electric to the Rod, will be confider’d under the 
next Experiment. 
If the Non-electric is pointed, and held in the 
fame Place as the former, a Light will appear from 
it the fame as from the electrical Body : For, as the 
Points of the two Rods are the Parts which ap- 
proach neareft: each other, the Attraction there will 
be ftrongeft : The Rays therefore, which diverged 
from the electrical Rod, will be attracted by, and 
made to converge towards, the Point of the non- 
electrical Rod, and will confequently be nearly of 
the fame Denfity at the one as the other > and the 
E e _ Velocity
