  annotated 
  by 
  Professor 
  Asa 
  Gray. 
  In 
  that 
  work, 
  which 
  was 
  

   then 
  well 
  up 
  to 
  date, 
  the 
  practice 
  of 
  the 
  gardener 
  was 
  explained 
  

   as 
  far 
  as 
  might 
  be, 
  and 
  a 
  great 
  amount 
  of 
  thoroughly 
  digested 
  

   material 
  was 
  placed 
  at 
  the 
  disposal 
  of 
  all 
  interested 
  in 
  culti- 
  

   vating 
  plants. 
  In 
  comparing 
  that 
  work 
  with 
  the 
  present, 
  one 
  is 
  

   struck 
  by 
  the 
  very 
  slight 
  change 
  in 
  practice 
  which 
  has 
  been 
  

   demanded 
  by 
  the 
  vast 
  advance 
  in 
  theoretical 
  knowledge. 
  The 
  

   old 
  rules, 
  many 
  of 
  which 
  were 
  very 
  plainly 
  empirical, 
  still 
  hold, 
  

   although 
  their 
  raison 
  cVMre, 
  may 
  be 
  put 
  in 
  a 
  different 
  manner 
  

   nowadays. 
  

  

  Professor 
  Weiss 
  has 
  given 
  us 
  a 
  clear, 
  idiomatic 
  translation, 
  and 
  

   with 
  his 
  work 
  no 
  fault 
  can 
  be 
  found. 
  But 
  the 
  original 
  is 
  of 
  very 
  

   uneven 
  quality. 
  In 
  some 
  places, 
  as 
  for 
  instance, 
  the 
  treatment 
  of 
  

   manures, 
  the 
  whole 
  might 
  serve 
  as 
  an 
  exercise 
  for 
  correction, 
  but 
  

   in 
  others, 
  for 
  example, 
  the 
  subject 
  of 
  shoots 
  and 
  their 
  manage- 
  

   ment, 
  all 
  the 
  statements 
  are 
  correct 
  and 
  telling. 
  In 
  the 
  hands 
  of 
  

   a 
  teacher, 
  this 
  volume 
  can 
  be 
  made 
  of 
  great 
  use 
  in 
  systematizing 
  

   and 
  coordinating 
  the 
  cardinal 
  facts 
  relative 
  to 
  the 
  vegetative 
  

   processes, 
  and 
  in 
  applying 
  them 
  to 
  the 
  practical 
  needs 
  of 
  the 
  

   gardener.

  Prize- 
  Question 
  pertaining 
  to 
  Physical 
  Science 
  proposed 
  by 
  

   the 
  Schnyder 
  von 
  Wartensee 
  Foundation 
  for 
  Arts 
  and 
  Sciences 
  

   at 
  Zurich* 
  — 
  The 
  Schnyder 
  von 
  Wartensee 
  Foundation 
  proposes, 
  

   for 
  the 
  year 
  1897, 
  the 
  following 
  prize-question 
  concerning 
  prob- 
  

   lems 
  in 
  the 
  domain 
  of 
  physics. 
  

  

  As 
  the 
  numbers 
  which 
  express 
  the 
  atomic 
  heats 
  of 
  the 
  elements 
  

   still 
  show 
  very 
  considerable 
  divergences, 
  the 
  researches 
  conducted 
  

   by 
  Professor 
  H. 
  F. 
  Weber 
  on 
  boron, 
  silicon 
  and 
  carbon, 
  regarding 
  

   the 
  increase 
  of 
  the 
  specific 
  heat 
  with 
  the 
  temperature, 
  are 
  to 
  be 
  

   extended 
  to 
  several 
  other 
  elements 
  prepared 
  as 
  pure 
  as 
  possible 
  

   and 
  also 
  to 
  combinations 
  or 
  alloys 
  of 
  them. 
  Further 
  the 
  densi- 
  

   ties 
  and 
  the 
  coefficients 
  of 
  thermal 
  dilatation 
  of 
  the 
  substances 
  

   investigated 
  are 
  to 
  be 
  ascertained 
  as 
  carefully 
  as 
  possible. 
  

  

  The 
  conditions 
  are 
  as 
  follows: 
  

  

  (I.) 
  The 
  treatises 
  handed 
  in 
  by 
  competitors 
  for 
  the 
  prize-ques- 
  

   tion 
  may 
  be 
  either 
  in 
  German, 
  French 
  or 
  English 
  and 
  must 
  be 
  

   sent 
  in 
  by 
  September 
  30th, 
  1897, 
  at 
  the 
  latest 
  to 
  the 
  address 
  given 
  

   in 
  paragraph 
  6. 
  

  

  (2.) 
  The 
  examination 
  of 
  the 
  treatises 
  will 
  be 
  entrusted 
  to 
  a 
  

   jury 
  composed 
  of 
  the 
  following 
  gentlemen 
  : 
  Professors 
  Pernet, 
  

   Zurich, 
  A. 
  Hantzsch, 
  Wurzburg, 
  E. 
  Dorn, 
  Halle-on-the-Saale, 
  

   T. 
  Wislicenus, 
  Leipzig 
  ; 
  also 
  G. 
  Lunge, 
  Zurich, 
  as 
  member 
  of 
  the 
  

   committee 
  proposing 
  the 
  prize-question. 
  

  

  (3.) 
  The 
  prize 
  committee 
  has 
  at 
  its 
  disposition 
  a 
  sum 
  of 
  four 
  

   thousand 
  five 
  hundred 
  francs,
