  was 
  anxious 
  to 
  receive 
  snails 
  for 
  investigation 
  in 
  order 
  to 
  find 
  

   out 
  how 
  far 
  the 
  statement 
  of 
  M. 
  E. 
  Seguy 
  held 
  true; 
  nothing 
  

   definite 
  was 
  yet 
  known 
  as 
  to 
  how 
  the 
  House-fly 
  normally 
  

   passed 
  through 
  the 
  winter 
  ; 
  there 
  was 
  no 
  evidence 
  to 
  support 
  

   the 
  old 
  idea 
  that 
  it 
  hibernated 
  in 
  the 
  adult 
  state 
  ; 
  and 
  the 
  

   probability 
  was 
  that 
  it 
  went 
  through 
  the 
  winter 
  either 
  as 
  a 
  

   larva 
  or 
  a 
  pupa 
  ; 
  but 
  proof 
  here 
  again 
  was 
  wanting, 
  and 
  much 
  

   further 
  investigation 
  in 
  various 
  directions 
  was 
  badly 
  needed.
