proof  preparation.  Running  lengthwise  over  the  tops  of  the  tables 
in  the  center  is  a  steel  shelf  eight  inches  high,  affording  room  for 
reagent  bottles.  Under  this  shelf  runs  the  1^2  inch  gas  main,  sup- 
plying each  student  with  gas  for  fuel  purposes  from  the  two  lever 
gas  cocks. 
Each  of  the  eight  students'  work  tables  provides  room  for  ten 
students  at  one  time.  At  the  end  of  four  of  these  long  tables  are 
located  alberene  stone  sinks,  2  feet  by  4  feet  in  dimensions,  pro- 
vided with  hot  and  cold  water,  steam  under  pressure  and  water  and 
hose  connections.  Each  pipe  has  a  shut-off  below  the  sink.  On 
the  inner  hall  wall  are  located  a  six-foot  alberene  stone  sink,  the 
lecture  or  demonstration  table  on  a  platform,  a  spacious  slate  black- 
board, cupboards  surmounted  by  percolating  racks,  and  a  sand  and 
steam  bath. 
The  lecture  table  is  provided  with  hot  and  cold  water,  gas,  steam 
under  pressure,  electric  current  and  air  pressure.  Over  the  lecture 
table  and  elsewhere  in  the  laboratory  are  located  pulleys  for  the 
exhibition  of  charts.  The  main  hood,  which  is  made  of  steel,  is 
found  in  the  northeast  corner  of  the  room.  The  central  portion 
reaches  a  height  of  about  nine  feet  and  to  each  side  a  wing  is  at- 
tached, located  under  the  high  windows,  but  high  enough  to  serve 
as  fume  chambers.  These  wings  empty  into  the  central  portion  of 
the  hood,  which  is  exhausted  at  the  top  through  the  window  at  the 
north  side  of  the  building  where  current  is  created  by  an  exhaust 
fan  operated  by  a  motor.  This  hood,  like  all  others  in  the  building, 
has  cupboards  below,  covered  with  soapstone.  All  portions  exposed 
to  fumes  are  asbestos  lined  and  painted  over  with  a  special  fume  and 
acid  proof  preparation.  This  laboratory  has  no  posts  in  view.  All 
of  the  supply  pipes,  such  as  hot  and  cold  water,  steam,  gas  and  the 
waste  pipes,  are  brought  up  through  the  floor  from  the  ceiling  below, 
where  attachment  to  the  various  supply  pipes  is  made.  The  floor 
of  this  laboratory,  like  all  other  floors  in  the  building,  has  a  top  coat- 
ing of  an  inch  and  a  half  of  cement  and  is  provided  with  floor  drains 
so  that  the  entire  floor  can  be  flushed.  It  is  not  the  purpose  to  flush 
the  floor,  except  possibly  in  parts,  but  in  case  the  water  leaks  any- 
where it  will  drain  off  into  the  sewer.  This  is  true  of  all  the  floors 
in  the  building,  each  floor  having  four  large  floor  drains.  All  floors 
are  covered  with  three  coats  of  special  cement  paint. 
This  main  pharmaceutical  laboratory  is  lighted  by  twelve  electric 
ceiling  fixtures,  the  eighteen-inch  shades  of  which  are  of  white
