the  validity  of  this  objection,  a new'  communication  was 
now  made  from  the  model  to  the  well,  con  lifting  of  one 
entire  wire,  pointed  at  the  end,  with  which  I repeated  the 
experiment  of  palling  the  model ; and  finding  no  fenfi- 
ble  difference  from  the  former  refults,  I then,  in  order 
to  apply  a rounded  end  to  this  perfect  communication, 
had  the  pointed  conductor,  which  was  previoully  made 
ufe  of,  foddered  on  to  the  end  of  the  wire  inltead  of  the 
other  point;  and  to  this  conductor  fo  foldered  I occa- 
fionally  applied  the  fmall  ball  which  wras  ufed  in  the  for- 
mer experiments,  and  which  has  hitherto  been  called  the 
rounded  end.  It  was  made  to  fit  upon  the  point  of  the 
foldered  conductor  by  means  of  a focket,  fo  as  to  render 
the  communication  perfect.  With  thefe  different  termi- 
nations, and  thus  circumftanced,  all  the  experiments 
were  repeated ; and  it  was  found,  that  the  refults  were 
rather  more  in  favour  of  the  doitrine  hitherto  advanced, 
than  before  the  communication  was  made  fo  perfect. 
It  having  been  farther  objected,  that  the  motion  of  the 
model  employed  in  thefe  experiments  was  confiderably 
greater  than  the  motion  of  a thunder-cloud,  I made  the 
following  experiment. 
exp.  xxxi.  The  weight  which  moved  the  model  in 
the  preceding  experiment  was  gradually  reduced  till  it 
was  nearly  balanced  by  the  friction;  and  when  the 
motion
