  This 
  exhaustive 
  monograph 
  on 
  the 
  Paleo- 
  

   zoic 
  fossil 
  sponges 
  was 
  begun 
  in 
  the 
  '80's. 
  Professor 
  Hall's 
  first 
  

   description 
  of 
  nine 
  species 
  of 
  Dictyophyton, 
  in 
  1863, 
  referred 
  them 
  

   to 
  the 
  Alga?. 
  In 
  1881,* 
  Whitfield 
  recognized 
  their 
  spongeous 
  

   nature; 
  and 
  in 
  1882, 
  an 
  advanced 
  notice 
  of, 
  and 
  in 
  1884, 
  a 
  num- 
  

   ber 
  of 
  plates 
  and 
  descriptive 
  text 
  of 
  a 
  report 
  with 
  nearly 
  the 
  same 
  

   title 
  as 
  the 
  present 
  volume, 
  were 
  issued 
  by 
  Hall 
  in 
  the 
  Thirty- 
  

   filth 
  Annual 
  Report 
  of 
  the 
  State 
  Museum 
  of 
  New 
  York. 
  The 
  128 
  

   species 
  are 
  distributed 
  in 
  seven 
  sub-families, 
  under 
  thirty-two 
  

   genera. 
  One 
  genus 
  is 
  reported 
  from 
  the 
  Lower 
  Helderberg. 
  

   The 
  latest 
  species 
  are 
  from 
  the 
  Keokuk 
  group, 
  and 
  the 
  largest 
  

   number 
  of 
  species 
  and 
  genera 
  are 
  from 
  the 
  Chemung 
  (82 
  species 
  

   in 
  16 
  genera). 
  The 
  plates 
  are 
  exquisite 
  examples 
  of 
  the 
  litho- 
  

   grapher's 
  work.

  This

  begins 
  with 
  a 
  general 
  

   account 
  of 
  the 
  demands, 
  uses 
  and 
  properties 
  of 
  building

   ornamental

  then 
  after 
  a 
  brief 
  geological 
  history 
  of 
  the 
  

   state, 
  the 
  different 
  areas 
  and 
  quarries 
  are 
  taken 
  up 
  and 
  described 
  

   separately 
  with 
  an 
  account 
  of 
  the 
  rocks 
  which 
  they 
  yield.

   reference

  colored 
  plates 
  of
