220  Pharmaceutical  Colleges  and  Associations.  {AmipriM?89arm* 
Stevenson,  Barnes  &  Jester  showed  bismuth  subnitrate  and  other  fine 
chemicals. 
Chas.  Shivers  exhibited  a  line  of  plasters  ;  also  the  original  roll  of  adhe- 
sive plaster  made  in  1854,  for  which  he  received  the  silver  medal  from  the 
Franklin  Institute,  and  which  is  still  in  good  condition. 
Bullock  &  Crenshaw  made  a  fine  display  of  chemical  apparatus,  notably 
such  of  modern  construction. 
W.  P.  Burk  &  Co.  showed  different  kinds  of  sponges  and  corks;  also  the 
Elma  Company's  medicated  candies. 
Gilpin,  Langdon  &  Co.,  of  Baltimore,  showed  a  line  of  assayed  drugs  in 
fine  powder  and  in  a  condition  suitable  for  percolation. 
In  the  Chemical  Laboratory,  J.  M.  Maris  &  Co.  exhibited  very  attractive 
modern  store  furniture,  among  which  was  an  elegant  walnut  prescription 
counter,  section  of  shelving,  etc.,  all  fitted  up  in  an  elaborate  manner.  Di- 
rectly opposite,  and  contrasting  with  these,  was  an  imitation  section  of  the 
store  of  Dr.  Glentwrorth,  of  Chester  and  Race  streets,  which  dates  back  to 
1812 ;  it  was  fitted  up  with  some  of  the  ancient  drawers,  bottles,  ointment 
jars  and  scales  loaned  for  the  purpose.  It  is  almost  needless  to  say  that  it 
attracted  great  attention. 
Professors  Sadtler  and  Trimble  displayed  old  and  modern  chemical  and 
physical  apparatus,  such  as  microscopes,  polariscopes,  spectroscopes,  dip- 
ping batteries,  furnaces,  etc.,  illustrating  the  vast  improvements  made  in 
their  construction. 
Professor  Remington  and  his  assistant,  F.  G.  Ryan,  Ph.  G.,  exhibited  an 
instructive  collection  of  pharmaceutical  apparatus  and  preparations,  the 
former  arranged,  in  a  number  of  instances,  to  show  the  evolution  that  has 
taken  place  in  the  same ;  thus,  the  pharmaceutical  stills  commenced  with 
the  old  leaden  one  formerly  in  use  by  Prof.  Procter,  and  ended  with  the  mod- 
ern "  Remington  still."  The  preparations  of  the  students  offered  in  compe- 
tition for  the  Pharmacy  prize  attracted  much  attention;  as  did 'the  model 
of  the  essential  oil  factory  of  Mr.  Todd  of  Nottawa,  Mich.;  also  the  prescrip- 
tion file  of  the  first  year  in  business  of  the  late  Prof.  Procter. 
Frederick  Gutekunst,  class  of  1853,  the  well-known  photographer,  exhib- 
ited specimens  of  his  art,  amongst  them  being  photographs  of  the  first 
building  occupied  by  the  College  on  Seventh  street,  the  second  building  on 
Zane  street,  the  present  building  on  Tenth  street,  and  the  proposed  new  front 
(the  latter  from  the  architect's  drawings). 
Robert  Shoemaker  &  Co.  exhibited  a  fine  line  of  drugs,  extract  of  beef,  etc. 
Whitall,  Tatum  &  Co.  displayed  an  extensive  variety  of  glass  ware  for  the 
use  of  druggists,  pharmacists,  and  for  other  purposes. 
William  Procter,  Jr.,  Co., showed  pepsin  products ;  A.  P.  Brown,  effervescing 
salts,  and  Keasby  &  Mattison  illustrated  magnesia  and  its  products,  of  which 
they  claim  to  be  the  largest  manufacturers  in  the  world. 
In  this  room  was  shown  the  evolution  of  the  drug  mill  from  the  model 
©f  the  one  found  in  the  ruins  of  Pompeii  (exhibited  by  Howard  B.  French) 
to  the  modern  ones,  like  that  of  Hance  Bros.  &  White;  also  the  evolution 
of  the  soda  water  fountain,  by  Chas.  Lippincott  &  Co.
