effe&s  occafioned  by  the  interpofition  of  thefe  different 
terminations. 
exp.  v.  On  repeating  the  firfl  experiment  (that  is, 
with  the  long  pointed  conductor  upon  the  model)  with 
ten  turns  of  the  wheel  only,  the  charge  remaining  in  the 
great  cylinder  was  immediately  received  on  the  hand; 
the  fenfation  it  occafioned  was  little  more  than  percep- 
tible. 
exp.  vi.  But  upon  repeating  the  fecond  experiment 
(that  is  with  the  long  rounded  conductor  upon  the  model) 
with  ten  turns  of  the  wheel  alfo,  the  charge  remaining 
was  taken;  but  the  fenfation  in  this  cafe  was  increafeeL 
confiderably. 
exp.  vii.  When  the  third-  experiment  was  repeated 
(that  is  with  a rounded  conductor  five  times  fhorter  than 
the  laft)  and  with  the  fame  number  of  turns,  the  fenfa- 
tion was  obferved  to  be  full  as  violent,  as  if  no  fuch  me- 
tallic interpofition  had  been  prefented  to  it. 
exp.  viii.  Upon  repeating  the  fourth  experiment  (that 
is,  with  the  pointed  conductor  equal  in  length  to  that  in 
the  laft  experiment)  and  with  ten  turns  of  the  wheel 
alfo,  the  fenfation  was  not  near  fo  confiderable ; for  it 
feemed  fomething  lefs  than  what  was  experienced  with 
the  long  rounded  conductor  in  the  iixth  experiment.
