denly  approached  the  brafs  drums  with  his  hand ; imme- 
diately an  explofion  took  place,  and  a difagreeable  fenfa- 
tion  was  perceived.  The  difcharge  was  then  made  at  the 
nearer  end  of  the  great  cylinder,  and  there  feemed  to  be 
no  difference  in  the  effect. 
exp.  xlv.  Upon  repeating  the  experiment  with  one 
machine  only,  and  after  the  fame  number  of  turns  of 
the  wheel  with  the  fame  velocity,  and  after  waiting  above 
eight  feconds  alfo,  the  fame  perfon  fuddenly  caufed  an 
explofion  with  the  fame  hand.  But  the  fenfation  in  con- 
fequence  of  it  was  very  different  from  the  laft  experi- 
ment; for  he  declared  it  was  little  more  (if  that)  than 
half  as  violent.  Thefe  laft  experiments  were  alfo  re- 
peated feveral  times  by  another  perfon,  who  gave  the 
fame  account  of  the  refults (t>. 
exp.  xl vi.  I now  charged  the  long  wire  only  and 
fully,  and  with  one  machine : the  explofion,  in  this  cafe, 
appeared  not  very  large,  but  of  a reddifh  hue ; and  the  dis- 
tance it  ftruck  at  was  not  more  than  one  inch  and  an  half ; 
however,  the  fenfation  acrofs  the  body  was  at  that  inftant

giving  lix  turns  to  the  wheel,  in  the  laft  experiment,  I ought  to  have  given 
twelve,  in  order  to  make  any  comparifon  between  the  effe&s  of  the  two  expe- 
riments t I therefore  limply  relate  the  experiments  as  they  were  made,  without 
making  any  dedudions  from  them.
