110    PHARMACEUTICAL  DEPARTMENT  OF  A  U.  S.  A.  HOSPITAL. 
most  of  the  articles  obtained  by  requisition  for  a  three  months 
supply  for  3600  beds. 
There  is  a  display  of  neatness  and  order  in  this  department, 
which  commends  itself  to  the  most  particular. 
Opening  a  back  door,  you  are  under  a  shed  which  affords  pro- 
tection for  the  railroad  cars,  of  which  I  have  spoken.  A  few 
yards  further  and  you  come  to  the  "Laboratory,"  14  by  16  feet, 
built  of  stone.  The  apex  of  the  roof  is  closed  by  a  sky-light, 
which  provides  for  the  exit  of  troublesome  smoke  and  fumes. 
Here  may  be  found  a  large-sized  cooking  stove,  and  some  of  the 
more  ordinary  apparatus  used  in  the  manufacture  of  pharmaceu- 
tical preparations. 
Almost  all  of  the  officinal  Tinctures  are  prepared  here,  in  quan- 
tities ranging  from  10  gallons,  to  ^-gallon.  Most  of  these  are 
made  by  maceration,  as  percolators,  except  Glass  Funnels,  are 
not  furnished. 
Many  of  the  Fluid  Extracts,  and  a  few  Solid  Extracts,  are 
made  here,  but  the  proper  means  for  the  nice  regulation  of  the 
heat  used  in  evaporating  is  not  available ;  those  that  I  have  had 
occasion  to  use,  however,  have  proved  efficient  in  the  ordinary 
doses.  Among  the  preparations  made  here  may  be  mentioned  : 
the  principal  Emplastra,  Pill  Ferri.  Carb.,  Hydrarg.  Biniodid., 
and  Protiodid.  Hydrarg  c.  Cretse,  Potassii  Sulphur et.,  and 
most  of  the  Syrups,  Cerates,  Ointments,  Wines,  and  Waters  of 
the  Pharmacopoeia. 
Medical  supplies  are  obtained  on  requisitions,  signed  by  the 
Surgeon  in  charge  of  the  hospital,  and  B approved"  by  the 
"Medical  Director,"  from  the  "Medical  Purveyor."  Most  of 
them  come  from  the  U.S.A.  Laboratory  located  in  this  city; 
others  bear  the  labels  of  our  widelv-known  manufacturers. 
Printed  "Supply  Tables"  enumerating  all  the  articles  furnished 
by  the  Government,  are  provided,  together  with  the  "allowance" 
for  a  certain  number  of  beds,  for  a  certain  time.  The  amount 
on  hand  must  be  stated,  as  well  as  the  amount  required.  In 
connection  with  this,  the  following  Table  may  prove  interesting :
