  The 
  garnets 
  in 
  the 
  general 
  mineral 
  collection 
  have 
  been 
  studied 
  

   and 
  the 
  species 
  of 
  each 
  specimen 
  determined 
  and 
  noted 
  on 
  the 
  label. 
  

  

  Mr. 
  G. 
  V. 
  Bailey, 
  formerly 
  with 
  Ward's 
  Natural 
  Science 
  Establish- 
  

   ment, 
  and 
  later 
  with 
  the 
  Smithsonian 
  Institution, 
  was 
  employed 
  for 
  

   about 
  ten 
  days 
  in 
  repairing 
  the 
  fossil 
  vertebrates. 
  He 
  repaired 
  some 
  

   of 
  the 
  plaster 
  casts 
  which 
  had 
  been 
  broken, 
  and 
  put 
  the 
  Ellenville 
  

   mastodon 
  tusk 
  in 
  good 
  condition, 
  fixing 
  in 
  place 
  many 
  loose 
  frag- 
  

   ments 
  of 
  the 
  interior 
  and 
  of 
  the 
  enamel. 
  

  

  He 
  removed 
  and 
  repaired 
  the 
  right 
  tusk 
  of 
  the 
  Cohoes 
  mastodon 
  

   and 
  replaced 
  it 
  in 
  its 
  proper 
  position; 
  soaked 
  the 
  dry 
  parts 
  of 
  the 
  

   skeleton 
  with 
  a 
  thin 
  solution 
  of 
  glue, 
  and 
  coated 
  them 
  with 
  paraffine 
  

   to 
  exclude 
  the 
  air. 
  His 
  work 
  was 
  highly 
  satisfactory 
  and 
  of 
  great 
  

   benefit 
  to 
  the 
  specimens. 
  

  

  The 
  case 
  of 
  precious 
  and 
  semi-precious 
  stones 
  has 
  been 
  some- 
  

   what 
  rearranged; 
  the 
  labels 
  revised 
  and 
  rewritten. 
  

  

  The 
  collection 
  of 
  shells 
  from 
  Mazatlan, 
  Mexico, 
  presented 
  by 
  

   P. 
  P. 
  Carpenter, 
  has 
  been 
  cleaned 
  and 
  the 
  broken 
  specimens 
  

   repaired. 
  

  

  In 
  order 
  to 
  better 
  illustrate 
  the 
  composition, 
  gradation 
  from 
  acid 
  

   to 
  basic 
  series, 
  and 
  other 
  relations, 
  of 
  the 
  Rosenbusch 
  Collection 
  ot 
  

   Massive 
  Rocks, 
  which 
  is 
  exhibited 
  on 
  the 
  second 
  floor 
  for 
  the 
  use 
  

   of 
  students; 
  a 
  translation 
  has 
  been 
  made 
  of 
  Rosenbusch's 
  table 
  of 
  

   massive 
  rocks, 
  and 
  is 
  placed 
  near 
  the 
  collection. 
  This 
  table 
  shows 
  at 
  

   a 
  glance 
  the 
  essential 
  constituents 
  of 
  the 
  rocks 
  ; 
  their 
  gradation 
  into 
  

   each 
  other; 
  the 
  method 
  of 
  naming 
  the 
  sub-varieties; 
  and 
  the 
  gen- 
  

   eral 
  relations 
  of 
  the 
  rocks 
  to 
  each 
  other. 
  

  

  The 
  drawers 
  in 
  the 
  cases 
  on 
  the 
  second 
  floor 
  have 
  been 
  numbered 
  

   consecutively, 
  and 
  a 
  catalogue 
  prepared 
  showing 
  briefly 
  the 
  con- 
  

   tents 
  of 
  each. 
  

  

  The 
  outer 
  row 
  of 
  table-cases 
  on 
  the 
  second 
  floor 
  contained 
  a 
  series 
  

   of 
  rocks 
  illustrating 
  the 
  stratigraphic 
  geology 
  of 
  the 
  state, 
  but 
  as 
  

   this 
  feature 
  is 
  more 
  fully 
  shown 
  in 
  the 
  wall-cases 
  on 
  that 
  floor, 
  it 
  was 
  

   deemed 
  advisable 
  to 
  use 
  the 
  tables-cases 
  for 
  a 
  new 
  feature. 
  

  

  A 
  scheme 
  has 
  been 
  prepared 
  for

  and 
  the 
  nucleus 
  of 
  the 
  collection 
  has 
  

   been 
  roughly 
  arranged. 
  This 
  collection
