Ohio  grape  ;  a  specimen  of  opium  produced  in  Tennessee,  containing 
over  ten  per  cent,  of  morphia. 
Chemical  and  pharmaceutical  apparatus  were  exhibited  by  J.  F.  Luhme 
&  Co.,  Mandelbaum  &  Mandel,  J.  Arnaboldi,  and  Dr.  W.  H.  Pile. 
Luhme  &  Co.,  exhibited  burette  stands  in  brass  and  wood,  burettes, 
graduated  pipettes/hydrometers,  thermometers,  Nicholson's  areometer  in 
glass,  apparatus  for  decomposing  water  and  collecting  the  .  products, 
graduated  mixing  bottles,  specific  gravity  balance,  apparatus  for  frac- 
tional distillation,  chemical  balances,  Luhme's  gas  stove,  Bunsen's  gas 
burners  and  O'Donnell's  retort  stand. 
Mandelbaum  &  Mandel  exhibited  a  variety  of  glass-ware  for  chemical 
and  pharmaceutical  use,  retort  stand,  separating  bottle,  alcoholometer  in 
case,  crucibles,  evaporating  dishes,  litre  mixing-bottle,  and  pill  machine. 
J.  Arnaboldi  exhibited  various  patters  of  thermometers,  hydrometers, 
hygrometers,  and  urinometers. 
Dr.  W.  H.  Pile,  of  Philadelphia,  exhibited  an  alcoholometer  in  case; 
various  patterns  of  hydrometers,  adapted  for  ammonia,  sugar,  sea-water, 
acids,  etc. ;  urinometer  in  case,  graduated  pipettes,  tubes  and  measures, 
stoppered  and  plain  specific  gravity  bottles. 
The  Washington  Pharmaceutical  Association  presented  several  speci- 
mens of  preparations  made  by  formulae  adopted  by  the  pharmaceutists 
and  physicians  of  the  District  of  Columbia. 
J.  W.  Shedden  exhibited  prepared  flour  of  bran,  adapted  for  use  of 
dyspeptics,  and  a  pyramid  containing  a  large  number  of  specimens  of 
mineraK 
W.  N.  Walton  &  Co.,  New  York,  exhibited  a  variety  of  druggists' 
glassware  of  their  own  make,  and  ornamented  with  their  patent  recess 
label. 
Geo.  W.  Stoeckel,  Pittsburgh,  Pa.,  exhibited  graduated  bottles,  from 
one  to  sixteen  ounces  capacity,  made  by  his  patent.  The  smaller  bottles 
are  graduated  by  drams,  and  the  larger  by  half-ounces.  They  are  a  great 
convenience  to  the  patient,  as  well  as  to  the  pharmaceutist. 
B.  0.  &  G.  0.  Wilson,  Boston,  Mass.,  exhibited  fifteen  specimens  of 
pressed  herbs,  in  pound  packages,  as  also  a  variety  of  one  and  two  ounce 
papers.  The  herbs  sold  by  this  house  are  superior  to  any  we  have  seen, 
and  deserve  high  commendation.  They  are  entirely  freed  from  all  the 
large  stems,  and  though  pressed  firmly,  the  leaves  retain  their  form  very 
perfectly. 
Becker  &  Sons,  of  Hudson  City,  N.  J.,  exhibited  four  patterns  of  their 
excellent  balances.  The  largest  balance  was  designed  for  analytical  pur- 
poses, and  was  one  of  the  most  sensitive  balances  we  have  seen.  It  was 
purchased  by  Dr.  Chandler  for  the  analytical  laboratory  of  the  School  of 
Mines.  Three  of  these  balances  were  adapted  for  prescription  use,  and 
were  sensitive  to  the  fiftieth  of  a  grain,  while  the  gold  scale  with  ten 
ounces  in  each  pan  would  turn  as  quickly.  We  would  especially  call  the 
attention  of  those  requiring  very  delicate  analytical  or  dispensing  bal- 
ances to  those  of  Becker  &  Sons'  make,  believing  them  to  be  equal  in 
accuracy  to  any  made  in  Europe. 
Henry  Troemner,  Philadelphia,  made  a  fine  display  of  balances.  Four 
patterns  of  "  Hoffman's"  patent  balance  were  shown,  as  also  some  hand- 
some gold  and  silver  plated  prescription  balances,  twine  boxes,  twine 
reels,  and  a  very  pretty  pattern  of  cork  press  in  brass.  The  "  Hoffman  " 
balance  has  the  working  parts  within  a  box  below  the  pans,  similar  in 
general  appearance  to  the  Beranger  balance,  but  has  a  single  beam,  and 
consequently  less  bearings.  One  balance  of  this  kind  was  finished  in  ele- 
gant style,  the  frame  of  the  box  being  solid  brass,  heavily  plated  with
