  The 
  theoretical 
  portions 
  perhaps 
  suffer 
  by 
  contrast 
  

   with 
  the 
  experimental 
  on 
  the 
  score 
  of 
  lack 
  of 
  concise 
  definitions. 
  

   To 
  take 
  but 
  one 
  instance, 
  there 
  is 
  apparantly 
  no 
  definition 
  given 
  

   of 
  a 
  fluid, 
  and 
  the 
  distinction 
  between 
  fluids 
  and 
  liquids, 
  though 
  

   tacily 
  assumed, 
  is 
  not 
  definitely 
  stated. 
  It 
  also 
  might 
  be 
  wished 
  

   by 
  some 
  that 
  the 
  author 
  had 
  introduced 
  the 
  conception 
  of 
  lines 
  

   of 
  force 
  in 
  the 
  section 
  on 
  electrostatics 
  and 
  not 
  have 
  left 
  it 
  until 
  

   magnetism, 
  or 
  rather 
  the 
  magnetic 
  action 
  of 
  a 
  current, 
  was 
  taken 
  

   up. 
  However, 
  this 
  and 
  other 
  points 
  more 
  or 
  less 
  pedagogical 
  in 
  

   nature, 
  suggested 
  by 
  the 
  arrangement 
  adopted 
  by 
  the 
  author, 
  are 
  

   after 
  all 
  matters 
  of 
  personal 
  opinion. 
  The 
  book 
  is 
  admirably 
  

   adapted 
  to 
  schools 
  with 
  limited 
  laboratory 
  equipment, 
  and 
  is 
  

   probably 
  in 
  the 
  first 
  rank 
  of 
  its 
  class.

  Summary 
  Report 
  of 
  the 
  Geological 
  Survey 
  Department 
  for 
  the 
  

   year 
  1896, 
  George 
  W. 
  Dawson, 
  Deputy 
  Head 
  and 
  Director. 
  In 
  

   this 
  last 
  document 
  is 
  found 
  a 
  brief 
  summary 
  of 
  the 
  more 
  import- 
  

   ant 
  results 
  of 
  the 
  survey 
  during 
  the 
  year. 
  The 
  Director 
  remarks 
  : 
  

   "During 
  the 
  past 
  year 
  very 
  notable 
  progress 
  has 
  been 
  made 
  in 
  

   development 
  of 
  the 
  mineral 
  resources 
  of 
  Canada, 
  both 
  in 
  the 
  way 
  

   of 
  actual 
  work 
  and 
  in 
  attracting 
  the 
  attention 
  and 
  interest 
  of 
  

   capital. 
  British 
  Columbia 
  has 
  begun 
  to 
  evidence 
  its 
  value 
  as 
  a 
  

   permanent 
  producer 
  of 
  the 
  precious 
  metals, 
  in 
  a 
  manner 
  long 
  fore- 
  

   seen 
  by 
  those 
  who 
  have 
  paid 
  attention 
  to 
  its 
  geological 
  structure 
  

   and 
  position. 
  In 
  Ontario, 
  wherever 
  the 
  Huronian 
  system 
  is 
  

   developed 
  and 
  has 
  been 
  examined, 
  valuable 
  mines 
  — 
  more 
  particu- 
  

   larly 
  those 
  of 
  gold. 
  — 
  are 
  being 
  discovered 
  and 
  opened 
  up. 
  In 
  

   Nova 
  Scotia, 
  renewed 
  interest 
  has 
  been 
  shown 
  in 
  gold 
  mining, 
  

   etc. 
  (p. 
  7.) 
  

  

  Corundum 
  has 
  been 
  discovered 
  in 
  Hastings 
  Co., 
  Ontario.
