neceflary with refpeCl to glafs globes and tubes, efpe- 
cially when new. If the dockings have once acquired 
this difpofition, they retain it for the day, or until a 
change of weather, and the experiment may be re- 
peated with fuccefs as often as one pleafes ; for no 
fooner are they difcha-rged of their electricity, than 
they are ready to receive it anew r ; nay, if fpeedily 
returned upon the leg, they catch it indantaneoufly, 
and may immediately be pulled off to exhibit a new 
explofion : what is Hill more furprifing, they feem 
to gather force by the frequency of the repetition, 
and, to fome certain degree, increafe in electrical 
power, provided they be all along kept warm and 
dry, and that the leg continue warm. 
Another cir'cumdance to be carefully attended to, 
is the manner in which they are to be taken off; for 
as to the putting of them on, it is a matter of indif- 
ference how that is performed. In taking them off, 
care muft be had not to feparate them ; for if that 
happens in pulling them off, all the electricity efcapes. 
The belt way, is to put the hand between the leg and 
the dockings, and pufh them off together. Nothing 
more remains to be done, than to pull them afunder; 
for upon that, they both of them exhibit a degree of 
eledtricity, which, when at the highed, is really fur- 
prifing. 
Before I conclude thefe occafional remarks, it may 
not be improper to obferve, that it is not abfolutely 
neceffary that the ftockings be applied to the bare 
leg; if a fine thread flocking feparate them from the 
leg, though left upon it when they are taken off, it 
does not much impair their eleClricity. But it is more 
..convenient to ufe the hand inflead of the leg. The
