  the

  the 
  clastic 
  rocks, 
  that 
  is, 
  the 
  conglom- 
  

   erates,

  and 
  tuffs 
  of 
  rocks 
  of 
  different 
  types;

  the 
  

   sandstones

  kaolin,

   etc.

  Mr. 
  Hoffmann's 
  report 
  con- 
  

   tains, 
  besides 
  analyses 
  of 
  fuels, 
  assays 
  of 
  ores 
  and 
  other 
  matters 
  

   of 
  economic 
  bearing, 
  also 
  a 
  number 
  of 
  points

  mineralogical 
  

   iuterest. 
  Among 
  these 
  we 
  note 
  the 
  identification

  the 
  follow- 
  

   ing 
  minerals, 
  of 
  several 
  of 
  which 
  analyses 
  are 
  given

  lollingite 
  

   from 
  Galway, 
  Peterborough 
  County, 
  Quebec, 
  containing 
  nearly 
  3 
  

   per 
  cent 
  of 
  cobalt 
  and 
  0*8 
  per 
  cent 
  of 
  nickel; 
  strontianite 
  from 
  

   Nepean, 
  Carleton 
  County, 
  Ontario, 
  where 
  it 
  occurs 
  in 
  veins 
  of 
  

   some 
  extent; 
  also 
  the 
  same 
  mineral 
  from 
  near 
  the 
  Horsefly 
  river, 
  

   Cariboo 
  district, 
  British 
  Columbia 
  ; 
  native 
  iron 
  in 
  minute 
  spherules 
  

   occurring 
  with 
  the 
  perthite 
  of 
  Cameron, 
  Nipissing, 
  Ontario 
  ; 
  

   pyrargyrite 
  from 
  the 
  Dardanelles

  West 
  

   Kootanie, 
  British

  This 
  volume 
  forms 
  the 
  first 
  part 
  of 
  a 
  comprehensive 
  

   work 
  on 
  meteorites, 
  which 
  will 
  be 
  warmly 
  welcomed 
  by 
  all 
  inter- 
  

   ested 
  in 
  this 
  subject. 
  Such 
  a 
  work 
  is 
  much 
  needed 
  at 
  the 
  present 
  

   time. 
  In 
  recent 
  years, 
  especially 
  during 
  the 
  past 
  two 
  decades, 
  the 
  

   literature 
  of 
  the 
  subject 
  has 
  increased 
  remarkably, 
  many 
  investi- 
  

   gations 
  after 
  the 
  improved 
  modern 
  methods 
  of 
  research 
  have 
  

   been 
  made 
  of 
  recent, 
  as 
  of 
  earlier, 
  falls, 
  and 
  the 
  collation 
  and 
  

   digestion 
  of 
  this 
  vast 
  amount 
  of 
  new 
  material 
  have 
  become 
  a 
  

   matter 
  of 
  the 
  highest 
  importance. 
  This 
  work 
  obviously 
  involves 
  

   great 
  labor 
  and 
  calls 
  for 
  the 
  knowledge 
  and 
  experience 
  which 
  are 
  

   possessed 
  in 
  a 
  high 
  degree 
  by 
  the 
  author. 
  

  

  The 
  present 
  part, 
  which 
  is 
  chiefly 
  devoted 
  to 
  a 
  description 
  of 
  

   the 
  mineral 
  constituents 
  of 
  meteorites, 
  will 
  be 
  followed 
  by 
  others 
  

   discussing 
  the 
  structure, 
  external 
  and 
  internal, 
  of 
  meteorites, 
  their 
  

   classification 
  and 
  finally 
  the 
  phenomena 
  of 
  fall 
  and 
  the 
  hypoth- 
  

   eses 
  advanced 
  to 
  explain 
  their 
  nature. 
  The 
  work 
  on 
  tins 
  minera- 
  

   logical 
  side 
  of 
  the 
  subject 
  has 
  been 
  performed 
  with 
  care 
  and 
  

   thoroughness 
  and 
  the 
  completion 
  of 
  the 
  whole 
  will 
  be 
  looked 
  for 
  

   with 
  interest.
