Am  Novr;Sarm" } Minutes  of  the  Pharmaceutical  Meeting.  5  59 
The  Nickel  Ores  of  Canada,  now  almost  the  entire  source  of  commercial 
nickel  in  the  country  were  shown  very  fully. 
The  Aluminum  Industry — which  has  assumed  such  large  proportions  lately 
— was  very  well  represented,  the  mineral  usually  worked  being  bauxite  or  oxide 
of  aluminum — the  metallic  aluminum  and  its  various  alloys  being  exhibited. 
A  very  interesting  exhibit  was  that  of  the  Frick  coke  works,  being  a  com- 
plete model  of  the  coke  ovens  at  Connellsville,  with  the  railways  for  distribut- 
ing the  coke  and  other  products. 
The  Platinum  industry,  as  exhibited  by  the  work  deposited  by  the  factory  of 
Heraeus  &  Co.,  at  Hanau,  Germany,  and  by  Johnson  &  Matthey,  of  London, 
was  very  imposing.  The  large  stills  used  in  acid  works,  which  are  now  lined 
with  gold  are  not  attacked  by  the  acids  while  the  concentration  is  being 
effected  so  that  nearly  absolutely  pure  acids  may  be  obtained  by  the  use  of  the 
lined  stills. 
A  special  chemical  exhibit  of  the  Roessler  &  Hasslacher  Chemical  Company 
showed  especially  cyanide  of  potassium  as  used  in  several  processes  in  the 
metallurgical  arts. 
The  products  of  the  Stassfurt  mines  of  Germany,  which  have  entirely  revo- 
lutionized the  potash  industry,  included  Carnallite,  a  chloride  of  potassium  and 
magnesium — Kieserite  and  Kainite,  these  salts  being  now  the  sources  of  potash 
of  commerce. 
The  output  of  the  various  factories  depending  on  these  minerals  for  their 
supply  is  enormous. 
Linseed  oil  works  were  represented  showing  their  various  products  of  oil, 
meal  and  cake  meal. 
Louisiana  Sugar  Industry,  showing  the  cane  in  its  different  states,  also 
ramie  fibre. 
Chocolate  Industry  of  Germany  made  a  very  fine  display. 
In  the  Agricultural  Exhibit,  among  other  things,  Canada  showed  a  mammoth 
cheese  weighing  2,200  pounds. 
The  various  Brewing  Companies'  exhibits  were  very  extensive  and  note- 
worthy. 
The  display  made  by  the  State  of  Pennsylvania  of  mineral  oils,  crude  and 
refined,  while  large,  was  completely  eclipsed  by  that  made  by  the  Standard  Oil 
Company.  This  exhibit  showed  the  crude  oil,  the  refined  article,  and  the  various 
products  obtained  in  the  processes  of  refining.  The  pipe  line  system  was  also 
illustrated  with  their  pumping  stations,  so  that  a  very  clear  idea  of  the  whole 
business  might  be  had  from  a  careful  study  of  the  display. 
Next  to  this  the  Russian  oil  display  commanded  great  attention,  as  it  was  a 
very  creditable  display  of  their  products. 
The  Russian  Stearic  Acid  Works  exhibited  glycerin  of  great  purity  and 
pure  white  oleic  acid. 
The  Florida  Rock  and  River  Phosphate  Companies  made  extensive  ex- 
hibits. 
The  Government  Building  contained  an  excellent  display  of  minerals,  and 
in  the  exhibit  of  the  War  Department,  also  various  rifle  and  artillery  powders, 
especially  the  smokeless  powder. 
In  the  Fisheries  Building  there  was  a  great  variety  of  products  exhibited, 
cod  liver  oil  being  prominent  among  them.
