   where

  except 
  

   during 
  the 
  numerous 
  journeys 
  which 
  he 
  undertook 
  after

  In

  he 
  visited 
  many 
  parts 
  of 
  Europe, 
  Palestine, 
  and 
  the 
  United 
  States. 
  

   He 
  was 
  starting 
  for 
  a 
  journey 
  in 
  Southern 
  Europe 
  when 
  he

  The 
  most 
  important 
  of 
  Gerhard 
  Yom 
  Kath's 
  numerous 
  papers 
  relate 
  

   to 
  mineralogy, 
  and 
  more 
  especially 
  to 
  chemical 
  mineralogy, 
  though 
  

   he 
  also 
  published 
  many 
  crystallographical 
  notes. 
  His 
  papers 
  have 
  

   been 
  greatly 
  praised 
  for 
  exactitude. 
  He 
  also 
  wrote 
  on 
  the 
  geology 
  

   of 
  the 
  countries 
  he 
  visited, 
  on 
  their 
  physical 
  geography, 
  and 
  their 
  

   inhabitants. 
  Although 
  his 
  name 
  is 
  attached 
  to 
  no 
  great 
  work, 
  he 
  

   filled 
  an 
  important 
  part. 
  To 
  agreeable 
  manners 
  and 
  wide 
  know- 
  

   ledge 
  he 
  added 
  an 
  extensive 
  acquaintance 
  with 
  scientific 
  men 
  

   throughout 
  the 
  civilized 
  world. 
  One 
  proof 
  of 
  his 
  influence 
  was 
  his 
  

   success 
  in 
  pursuading 
  the 
  Prussian 
  Government 
  to 
  purchase 
  for 
  the 
  

   Mineralogical 
  Museum 
  at 
  Bonn 
  the 
  private 
  mineral 
  collection, 
  con- 
  

   taining 
  14,000 
  specimens, 
  of 
  Krantz, 
  the 
  well-known 
  mineral-dealer, 
  

   at 
  a 
  price 
  of 
  144,000 
  marks 
  (=£7200). 
  He 
  was 
  an 
  honorary 
  or 
  

   corresponding 
  Member 
  of 
  numerous 
  Academies 
  and 
  Societies 
  in 
  

   various 
  parts 
  of 
  Europe 
  and 
  in 
  the 
  United 
  States.

  Kjerulf's 
  contributions

  are 
  extensive, 
  and 
  contain
