  specimens 
  

   of 
  industrial 
  raw 
  materials 
  not 
  heretofore 
  represented 
  in 
  the 
  col- 
  

   lections, 
  which 
  had 
  been

  to 
  the 
  department 
  by

  There

  of 
  silks, 
  fur 
  fabrics, 
  and 
  drapery 
  textiles 
  contributed 
  by 
  

   American 
  manufacturers 
  to 
  show 
  the 
  progress 
  of 
  textile 
  industries 
  

   in 
  this 
  country. 
  

  

  To 
  the 
  collections 
  arranged 
  to 
  show 
  the 
  importance 
  of 
  wood 
  and 
  

   the 
  industries 
  based 
  upon 
  the 
  use 
  of 
  that 
  raw 
  material, 
  there 
  were 
  

   added 
  two 
  series 
  of 
  specimens 
  illustrating 
  the 
  manufacture 
  and 
  use 
  

   of 
  sulphite 
  wood 
  pulp 
  for 
  writing 
  papers, 
  one 
  showing 
  in 
  detail 
  

   the 
  steps 
  in 
  the 
  process, 
  and 
  the 
  other 
  the 
  exact 
  quantities 
  of 
  each 
  

   ingredient 
  entering 
  into 
  100 
  pounds 
  of 
  finished 
  paper; 
  also 
  exhibits 
  

   showing 
  the 
  importance 
  and 
  uses 
  of 
  American 
  walnut, 
  many 
  ex- 
  

   amples 
  of 
  articles 
  turned 
  from 
  wood, 
  and 
  specimens 
  of 
  laminated 
  

   wood 
  wheels 
  for 
  motor 
  vehicles. 
  

  

  The 
  collections 
  in 
  the 
  division 
  of 
  medicine 
  were 
  enlarged 
  by 
  ex- 
  

   tensive 
  series 
  of 
  specimens 
  showing 
  the 
  manufacture 
  of 
  surgical 
  

   dressings, 
  pills, 
  plasters, 
  surgical 
  ligatures, 
  and 
  clinical 
  thermome- 
  

   ters; 
  specimens 
  of 
  essential 
  oils 
  and 
  related 
  aromatic 
  substances; 
  

   important 
  alkaloids 
  and 
  alkaloidal 
  salts 
  used 
  in 
  medicine; 
  and 
  a 
  

   series 
  of 
  charts 
  showing 
  the 
  treatment 
  of 
  rabies, 
  typhoid 
  fever, 
  and

  Graphic 
  arts. 
  — 
  The 
  specimens 
  acquired 
  in 
  the 
  division, 
  while 
  less 
  

   than 
  half 
  in 
  number, 
  are 
  still 
  fully 
  as 
  important, 
  artistically 
  and 
  

   technically, 
  as 
  the 
  1920-21 
  specimens. 
  The 
  most 
  important 
  indi- 
  

   vidual 
  gift 
  was 
  that 
  of 
  the 
  sixteenth 
  century 
  methods 
  of 
  making 
  

   type, 
  in 
  which 
  all 
  the 
  specimens 
  were 
  made 
  by 
  or 
  prepared 
  by 
  Mr. 
  

   Dard 
  Hunter, 
  Chillicothe, 
  Ohio. 
  Mr. 
  Hunter 
  himself 
  made 
  the 
  

   punches, 
  struck 
  the 
  matrices, 
  and 
  cast 
  the 
  type. 
  This 
  is 
  one 
  of 
  a 
  

   series 
  consisting 
  of 
  printer's 
  ink, 
  paper, 
  and 
  type 
  making, 
  which, 
  

   with 
  the 
  promised 
  modern 
  methods 
  of 
  type 
  making, 
  will 
  be 
  about 
  

   complete. 
  Several 
  gifts 
  combined 
  have 
  greatly 
  improved 
  both 
  the 
  

   technical 
  and 
  historical 
  series 
  of 
  collotype. 
  The 
  Campbell 
  Art 
  Co., 
  

   of 
  Elizabeth, 
  N. 
  J., 
  gave 
  a 
  valuable 
  and 
  instructive 
  technical 
  exhibit 
  

   of 
  color 
  printing, 
  and 
  beautiful 
  examples 
  of 
  the 
  process 
  were 
  also 
  

   furnished 
  by 
  Foster 
  Bros., 
  of 
  Boston, 
  the 
  Medici 
  Society 
  of 
  America 
  

   (Inc.), 
  and 
  by 
  Rudolf 
  Lesch, 
  of 
  New 
  York 
  City. 
  These 
  are 
  ex- 
  

   amples 
  of 
  the 
  finest 
  collotype 
  work 
  being 
  produced 
  to-day, 
  and 
  

   make 
  an 
  excellent 
  showing 
  of 
  this 
  process 
  of 
  photomechanical 
  re- 
  

   production. 
  A 
  new 
  process 
  for 
  reprinting 
  books 
  has 
  been 
  developed 
  

   by 
  the 
  Polygraphic 
  Co., 
  of 
  Berne, 
  Switzerland, 
  who 
  donated 
  a 
  com- 
  

   plete 
  exhibit. 
  In 
  this 
  so-called 
  Manul 
  process 
  the 
  negative 
  is 
  ob-
