﻿CENTH'S 
  TYPES! 
  

  

  In 
  the 
  purcliase 
  of 
  a 
  large 
  lot 
  of 
  specimens, 
  constituting 
  the 
  pick 
  of 
  everything 
  

   of 
  historical 
  or 
  specimen 
  value, 
  iu 
  the 
  collection 
  of 
  the 
  late 
  M. 
  E. 
  Howell, 
  we 
  are 
  

   able 
  to 
  afford 
  our 
  customers 
  a 
  rare 
  opportunity 
  to 
  acquire 
  certain 
  choice 
  things 
  

   possessing 
  unusual 
  merit. 
  These 
  are 
  no 
  less 
  than 
  the 
  original 
  specimens 
  (or 
  

   portions 
  of 
  them) 
  described 
  by 
  the 
  late 
  Dr. 
  F. 
  A. 
  Genth. 
  and 
  later 
  presented 
  to 
  

   Mr. 
  Howell. 
  .Many 
  are 
  excellent 
  crystallizations, 
  others 
  mere 
  fragments. 
  The 
  

   collection 
  covers 
  the 
  period 
  about 
  I8G0-95 
  and 
  includes, 
  besides 
  this 
  series 
  of 
  

   "notables," 
  many 
  fine 
  European 
  things 
  gathered 
  by 
  Mr. 
  Howell 
  and 
  his 
  brother 
  

   Prof. 
  S. 
  B 
  Howell, 
  who 
  formerly 
  occupied 
  the 
  chair 
  of 
  Mineralogy 
  in 
  the 
  Uni- 
  

   versity 
  of 
  Pennsylvania. 
  There 
  are 
  few 
  duplicates 
  and 
  the 
  distribution 
  of 
  the 
  

   collection 
  will 
  be 
  as 
  rapid 
  as 
  that 
  of 
  the 
  '' 
  Trautwine," 
  of 
  which 
  there 
  is 
  little 
  of 
  

   importance 
  remaining. 
  The 
  labels 
  are 
  scientifically 
  exact, 
  the 
  words 
  "Genth

  in 
  Prof. 
  Howell's

  being

  — 
  purchasable, 
  

   exchangeable
