  Mr. 
  Faxon 
  and 
  his 
  father. 
  Sixty 
  sets, 
  each 
  containing 
  172 
  num- 
  

   bers, 
  representing 
  39 
  species 
  and 
  their 
  varieties 
  and 
  forms, 
  have 
  

   been 
  prepared 
  and 
  form 
  a 
  collection 
  indispensable 
  to 
  all 
  students 
  

   of 
  Sphagna. 
  Specimens 
  of 
  all 
  the 
  species 
  and 
  varieties 
  were 
  sent 
  

   by 
  Prof. 
  Eaton 
  to 
  the 
  well-known 
  sphagnologist, 
  Dr. 
  C. 
  Warn- 
  

   storf, 
  whose 
  suggestions 
  as 
  to 
  nomenclature 
  have 
  been 
  closely 
  

   followed. 
  The 
  specimens 
  are 
  remarkably 
  fine 
  and 
  offer 
  a 
  richness 
  

   ol 
  material 
  for 
  the 
  study 
  of 
  North 
  American 
  forms 
  of 
  the 
  genus 
  

   unequalled 
  by 
  any 
  previous 
  collection, 
  The 
  eastern 
  portions 
  of 
  

   the 
  United 
  States 
  are 
  very 
  fully 
  represented 
  by 
  sppcimens 
  col- 
  

   lected 
  mainly 
  by 
  Mr. 
  Faxon 
  and 
  Prof. 
  Eaton. 
  The 
  forms 
  from 
  the 
  

   South 
  and 
  West, 
  though 
  not 
  so 
  fully, 
  are 
  well 
  represented 
  by 
  the 
  

   contributions 
  of 
  a 
  number 
  of 
  well-known 
  collectors. 
  The 
  distri- 
  

   bution 
  of 
  the 
  sets 
  is 
  in 
  charge 
  of 
  Mr. 
  G. 
  F. 
  Eaton, 
  whose 
  address 
  

   is 
  70 
  Sachem 
  street, 
  New 
  Haven, 
  to 
  whom 
  those 
  desiring 
  sets 
  

   should 
  apply 
  for 
  information.

  Ueber

  The 
  present 
  paper 
  lrom 
  

   Pringsheim's 
  Jahrbuecher 
  is 
  a 
  continuation 
  of 
  one 
  already 
  noticed 
  in 
  

   the 
  April 
  number 
  of 
  this 
  Journal. 
  In 
  that 
  paper 
  he 
  gave 
  an 
  account 
  

   of 
  his 
  study 
  of 
  the 
  development 
  of 
  the 
  perithecia 
  of 
  Sphserotheca, 
  in 
  

   which 
  only 
  a 
  single 
  ascus 
  is 
  formed. 
  Here 
  he 
  extends 
  his 
  observa- 
  

   tions 
  to 
  perithecia 
  with 
  several 
  asci 
  as 
  illustrated 
  by 
  Erysiphe 
  

   communio. 
  In 
  this 
  case, 
  the 
  fertilized 
  egg-nucleus 
  divides 
  into 
  

   two 
  and 
  then 
  into 
  four 
  and 
  the 
  oogonium 
  increases 
  in 
  length 
  with 
  

   the 
  formation 
  of 
  cross-septa 
  until 
  it 
  forms 
  a 
  curved 
  tube 
  with 
  a 
  

   row 
  of 
  from 
  five 
  to 
  eight 
  nuclei. 
  The 
  septa 
  then 
  form 
  simul-
