258  Papers  relative  to  an  Occident 
third  observation.  The  feveral  effects  obferved  in 
the  four  laft  experiments  agreeing  fo  exadtly  with  thofe 
in  the  four  firft,  prove,  at  leaft  fo  far,  that  rounded  ends, 
in  thefe  cafes,  received  the  fluid  lefs  readily,  and  in  lefs 
quantity,  than  points. 
But,  before  other  experiments  are  related,  it  may  be 
proper  to  take  notice  of  what  pafled  at  the  ihort  fpout 
upon  the  model  during  the  making  of  the  four  firft  ex- 
periments ; becaufe  the  confequences  to  be  drawn  from 
thence  are  very  material. 
exp.  ix.  In  the  firft  experiment  (when  the  long 
pointed  conductor  was  put  upon  the  model,  and  whilft 
the  wheel  was  turning)  a very  fmall  fpark  might  be 
taken  from  the  fhort  fpout ; but  if  the  hand,  or  a wire, 
was  applied,  which  communicated  with  the  well,  and 
continued  in  contact  with  the  fhort  fpout,  or  if  it  was 
connected  with  the  long  fpout,  the  fmall  ftream  of  light 
feen  before  at  the  top  of  that  fpout  now  ceafed. 
exp.  x.  But  this  was  not  the  cafe  when  the  third  ex- 
periment was  repeated  (that  is,  with  the  fhort  rounded 
conductor) ; for  this,  by  reafon  of  its  greater  diftance 
from  the  cylinder,  and  the  nature  of  its  termination,  did 
not  draw  a fufficient  quantity  of  the  charge  from  the 
great  cylinder  to  caufe  the  leaft  appearance  of  a ftream 
of  light,  as  in  the  former  cafe.
