  an 
  exceptional 
  amount 
  of 
  study 
  to 
  be 
  given 
  to 
  it 
  by 
  the 
  professors 
  

   resident 
  there. 
  The 
  first 
  part 
  is 
  given 
  up 
  to 
  the 
  records 
  of 
  the 
  

   boring, 
  including 
  a 
  full 
  description 
  of 
  the 
  methods. 
  The 
  tempera- 
  

   tures 
  were 
  taken 
  at 
  numerous 
  intervals 
  and 
  show 
  a 
  rectilinear 
  

   temperature 
  gradient 
  of 
  21-5° 
  per 
  kilometer, 
  beginning 
  with 
  8*3° 
  

   at 
  the 
  surface. 
  The 
  rocks 
  penetrated 
  are 
  limestones 
  of 
  the 
  Upper 
  

   Cretaceous. 
  Lists 
  of 
  the 
  fossils 
  identified 
  are 
  given 
  by 
  Dr. 
  Ravn, 
  

   who 
  shows 
  also 
  their 
  position 
  in 
  the 
  Upper 
  Cretaceous 
  series 
  from 
  

   Turonian 
  to 
  Danien 
  inclusive. 
  Thus 
  the 
  underground 
  geology 
  

   of 
  Denmark, 
  a 
  land 
  whose 
  surface 
  is 
  mostly 
  of 
  Pleistocene 
  and 
  

   recent 
  formations, 
  is 
  carried 
  to 
  a 
  depth 
  of 
  more 
  than 
  half 
  a 
  mile.

  The 
  possibility 
  of 
  transmitting 
  to 
  future 
  gener- 
  

   ations 
  any 
  of 
  the 
  characters 
  acquired 
  during 
  the 
  lifetime 
  of 
  the 
  

   individual 
  has 
  been 
  very 
  generally 
  doubted 
  or 
  even 
  denied 
  by 
  

   many 
  biologists. 
  An 
  increasing 
  mass 
  of 
  evidence 
  from 
  recent 
  

   experiments 
  has 
  tended 
  to 
  demonstrate 
  the 
  independence 
  of 
  the 
  

   characters 
  contained 
  in 
  the 
  germ 
  cells 
  from 
  bodily 
  influences. 
  Yet 
  

   there 
  are 
  still 
  those 
  who 
  hold 
  that 
  under 
  certain 
  circumstances 
  it 
  

   may 
  occasionally 
  happen 
  that 
  a 
  long 
  continued 
  or 
  violent 
  stim- 
  

   ulus 
  may 
  so 
  modify 
  the 
  body 
  of 
  an 
  organism 
  as 
  to 
  be 
  transferred 
  

   to 
  the 
  germ 
  cells 
  and 
  thus 
  cause 
  a 
  similar 
  modification 
  in 
  the 
  

   future 
  offspring. 
  Semon 
  belongs 
  to 
  this 
  latter 
  class. 
  In 
  this 
  

   book 
  he 
  presents 
  an 
  impartial 
  and 
  masterful 
  discussion 
  of 
  the 
  

   problem, 
  and 
  reviews 
  the 
  evidence 
  which 
  leads 
  him 
  to 
  the 
  con- 
  

   viction 
  that 
  these 
  so-called 
  acquired 
  characters 
  may 
  be 
  trans-

  Whether 
  regarded 
  

   as 
  a 
  means 
  of 
  preserving 
  peace 
  or 
  an 
  engine 
  of 
  war, 
  the

  of 
  

   modern 
  times 
  is 
  a 
  subject 
  of 
  great 
  interest 
  to 
  many 
  people, 
  and 
  

   those 
  not 
  especially 
  informed 
  in 
  regard 
  to 
  it 
  will 
  find 
  in 
  this 
  little 
  

   book 
  an 
  excellent 
  summary 
  of 
  the 
  whole 
  matter. 
  It 
  takes 
  up 
  the 
  

   question 
  of 
  design, 
  the 
  various 
  materials 
  and 
  steps 
  involved 
  in 
  

   construction, 
  and 
  finally 
  the 
  point 
  of 
  most 
  serious 
  moment 
  to 
  the 
  

   tax-payers, 
  namely, 
  the 
  cost 
  of 
  this 
  expensive 
  luxury.
