  in 
  the 
  Mixteca 
  Alta 
  of 
  Southern 
  Mexico, 
  although 
  

   not 
  in 
  a 
  condition 
  to 
  be 
  sectioned, 
  leads 
  us 
  to 
  hope 
  the 
  missing 
  

   links 
  will 
  be 
  discovered." 
  

  

  To 
  these 
  conclusions 
  we 
  fully 
  assent, 
  only 
  finding 
  fault 
  with 
  

   the 
  first 
  premise. 
  World-wide 
  collection 
  is 
  always 
  in 
  order, 
  

   although 
  there 
  is 
  still 
  plenty 
  to 
  do 
  on 
  the 
  cycad 
  ancestry 
  near 
  

   the 
  University 
  of 
  Chicago 
  in 
  the 
  Permo-Carboniferous 
  which 
  has 
  

   already 
  yielded 
  the 
  remarkable 
  Codonotheca, 
  near 
  the 
  University 
  

   of 
  Virginia 
  in 
  the 
  finely 
  developed 
  Rhatic 
  plant 
  beds, 
  and 
  near 
  

   Yale 
  in 
  the 
  Connecticut 
  Trias, 
  as 
  well 
  as 
  near 
  several 
  other 
  places 
  

   in 
  the 
  University 
  belt. 
  Workers 
  have 
  been 
  here 
  too 
  few, 
  means 
  

   limited, 
  and 
  criticism 
  meager.

  — 
  The 
  striking 
  feature 
  of 
  the 
  present 
  report 
  from 
  

   the 
  Carnegie 
  Institution 
  is 
  the 
  account 
  of 
  the 
  work 
  accomplished 
  

   in 
  various 
  directions 
  in 
  the 
  activities 
  made 
  necessary 
  by 
  the 
  

   world 
  war 
  ; 
  a 
  considerable 
  part 
  of 
  the 
  staff 
  of 
  the 
  Institution 
  was 
  

   engaged 
  in 
  this 
  way. 
  One 
  special 
  work 
  dwelt 
  upon 
  is 
  the 
  pro- 
  

   duction 
  of 
  optical 
  glass 
  by 
  the 
  Geophysical 
  Laboratory, 
  which 
  

   was 
  needed 
  at 
  once 
  for 
  a 
  variety 
  of 
  instruments 
  used 
  by 
  the 
  ord- 
  

   nance 
  departments 
  of 
  the 
  Army 
  and 
  Navy. 
  It 
  is 
  noteworthy 
  

   that, 
  within 
  a 
  year, 
  the 
  production 
  of 
  uncut 
  optical 
  glass 
  was 
  by 
  

   this 
  means 
  raised 
  from 
  less 
  than 
  a 
  ton 
  per 
  month 
  to 
  more 
  than 
  

   one 
  hundred 
  tons. 
  Another 
  example 
  of 
  war 
  activities 
  is 
  fur- 
  

   nished 
  by 
  the 
  work 
  of 
  the 
  Nutrition 
  Laboratory, 
  concerning 
  the 
  

   effects 
  of 
  short 
  rations. 
  The 
  director 
  of 
  the 
  Laboratory 
  had 
  at 
  

   his 
  disposal 
  two 
  squads 
  of 
  men, 
  a 
  dozen 
  each, 
  of 
  the 
  Y. 
  M. 
  C. 
  A. 
  

   College 
  of 
  Springfield, 
  Mass. 
  These 
  men 
  maintained 
  their 
  regu- 
  

   lar 
  college 
  work 
  but 
  were 
  put 
  on 
  a 
  low 
  diet 
  and 
  kept 
  under 
  obser- 
  

   vation 
  and 
  experiment 
  from 
  October 
  1917 
  to 
  February 
  1918. 
  

   Important 
  among 
  the 
  results 
  is 
  the 
  proof 
  that 
  "the 
  normal 
  adult 
  

   man 
  may 
  subsist 
  for 
  some 
  months 
  on 
  a 
  severely 
  restricted 
  diet 
  

   and 
  during 
  this 
  time 
  may 
  undergo 
  marked 
  losses 
  in 
  body 
  weight 
  

   and 
  in 
  nitrogenous 
  reserves 
  without 
  serious 
  impairment 
  of 
  his 
  

   mental 
  and 
  muscular 
  efficiency." 
  

  

  The 
  report 
  also 
  dwells 
  in 
  particular 
  upon 
  the 
  work 
  of 
  the 
  non- 
  

   magnetic 
  ship 
  "Carnegie," 
  which 
  since 
  her 
  launching 
  in 
  1909, 
  

   has 
  traversed 
  in 
  her 
  surveys 
  an 
  aggregate 
  of 
  nearly 
  190,000 
  

   nautical 
  miles. 
  It 
  is 
  further 
  noted 
  that 
  the 
  Eugenics 
  Record 
  

   Office, 
  established 
  by 
  Mrs. 
  E. 
  H. 
  Harriman 
  in 
  1910, 
  and 
  located 
  

   at 
  Cold 
  Spring 
  Harbor, 
  came 
  under 
  the 
  control 
  of 
  the 
  Carnegie 
  

   Instil 
  ill 
  ion 
  on 
  June 
  1, 
  1918, 
  with 
  an 
  endowment 
  gift 
  of 
  $300,000 
  

   from 
  Mrs. 
  Harriman 
  to 
  assist 
  in 
  its 
  work. 
  

  

  The 
  total 
  income 
  of 
  the 
  Institution 
  now 
  amounts 
  to 
  $1,112,000
