PROCEEDINGS  OF  THE 
Charles  T.  Carney,  chairman  of  the  Committee  appointed  to 
examine  the  articles  on  exhibition,  read  the  following  report, 
which  was  adopted  : — 
The  Committee  appointed  to  report  upon  the  Exhibition  of  Specimens, 
submit  the  following  remarks  : 
Of  course,  owing  to  the  limited  time  at  their  disposal,  they  can  speak 
only  in  general  terms,  except  in  those  cases  where  special  information  upon 
any  specimens  has  been  given  them  by  the  exhibitors: — 
CHEMICALS. 
We  notice  a  collection  of  twenty-four  bottles  of  very  fine  looking  chemicals 
from  Messrs.  Chas.  Pfizer  &  Co.,  of  New  York;  prominent  among  them  are 
the  specimens  of  Strychnia  and  its  salts,  Pyro-Phosphate  of  Iron,  Hypo- 
Phosphite  of  Lime,  Ammonio-Citrate  of  Iron,  Citrate  of  Iron  and  Quinia. 
Red-Precipitate  and  re-sublimed  Iodine. 
A  collection  of  seven  bottles  of  chemicals,  made  by  Messrs.  Gamier, 
Lamoureux  &  Co.,  of  Paris,  exhibited  by  F.  A.  Reichard,  of  New  York,  are 
worthy  attention  for  their  fine  appearance  and  apparent  excellence;  among 
them  are  Citrate  of  Iron,  Tartrate  of  Potassa  and  Iron,  Iron  by  Hydrogen  and 
Soluble  Cream-Tartar. 
Geo.  W.  Weyman,  of  Pittsburg,  Pa.,  has  on  exhibition  several  specimens 
of  "Crude  Mineral  Oils,"  from  the  great  oil-bearing  district  of  Western 
Pennsylvania,  which  are  quite  interesting, — presenting  as  they  do  such  a 
variety  of  physical  characteristics,  though  taken  from  localities  almost  iden- 
tical. 
Specimens  of  Chloride  of  Propylamine  and  Valerianate  of  Ammonia,  in 
fine  crystals,  exhibited  by  Messrs.  Benj.  J.  Crew  &Co.,  of  Philadelphia,  are, 
in  the  opinion  of  your  Committee,  the  best  they  have  ever  seen. 
Eight  specimens  of  chemicals  are  exhibited  by  Messrs.  W.  J.  M.  Gordon 
&  Bro.,  Cincinnati;  among  them  we  notice  specially  Chromic  Acid  in 
crystals,  Iodide  of  Lead,  Hydrastin,  Naphthalin  and  Sulphate  of  Sanguina- 
rina  as  being  very  excellent. 
Eleven  specimens  of  chemicals  exhibited  by  Edward  Parrish,  Philadel- 
phia ;  among  them  some  of  the  more  rare  compounds — such  as  Tannate  of 
Bismuth,  Neutral  Benzoate  of  Ammonia,  Benzoate  of  Soda,  Terbenzoate 
of  Iron,  Nitro-Prusside  of  Sodium  and  Aloin  are  noticed  as  worthy  the 
attention  of  members  present. 
Some  very  fine  srJecimens  of  pure  inodorous  Glycerine,  made  by  Henry 
C.  Bower,  Philadelphia,  on  exhibition  by  Charles  Bullock,  of  Philadelphia, 
attract  our  attention.  We  find  the  sp.  grav.  to  be  1-225,  and  testing  it  in 
the  imperfect  manner  at  our  command,  judge  it  to  be  a  very  superior 
article, — quite  equal  to  any  foreign  we  have  seen—  and  we  regard  it  with 
gratification,  as  being  an  advance  in  home  manufactures. 
A  specimen  of  Sulphate  of  Ammonia,  from  Gas  Liquor,  is  also  exhibited 
by  the  same  parties.
