warming  apartments.  As  early  as  1826  he  became  a  Manager 
of  the  Schuylkill  Navigation  Company,  and  during  16  years  that 
he  was  connected  with  it,  saw  the  transportation  of  anthracite 
coal  increase  from  35,000  tons,  in  1825,  to  953,899  tons  in  1841, 
while  in  1864  it  reached  nearly  ten  millions  of  tons. 
Xji  conclusion,  we  may  appropriately  refer  to  our  late  Vice- 
President,  not  only  as  a  man  of  thorough  integrity  and  upright- 
ness, but  as  illustrating  in  his  example  how  a  successful  business 
man,  devoted  zealously  to  his  own  interests,  may  at  the  same  time 
be  instrumental  in  developing  and  promoting  the  interests  of  his 
fellow  men,  and,  by  bringing  all  his  powers  into  activity,  may 
accomplish  a  work  in  the  world  which  will  cause  him  to  be  re- 
garded as  an  example  of  energy  and  philanthropy. 
ON  ARNICA  PLASTER.

The  preparations  of  arnica  flowers  are  receiving  and  rapidly 
gaining  favor  with  the  medical  profession,  being  highly  extolled 
in  domestic  practice  as  a  most  useful,  popular  and  efficacious 
remedy,  applied  to  sprains,  bruises  and  rheumatic  affections  gene- 
rally. 
The  forms  usually  employed  are  the  tincture  and  plaster  ;  both 
these  preparations,  as  well  as  an  alcoholic  extract  (solid)  have 
been  introduced  into  the  last  edition  of  the  Pharmacopoeia. 
In  accordance  with  the  suggestion  of  our  Professor  of  Phar- 
macy, the  subject  of  the  preparation  of  arnica  plaster  has  been 
adopted.  Previous  to  making  the  plaster  several  extracts  were 
prepared,  with  the  view  of  ascertaining  the  quantity  of  extract 
respectively  yielded  by  several  processes.  The  first  was  prepared 
according  to  the  formula  given  in  the  United  States  Pharmaco- 
poeia, as  follows  :    Take  of 
Arnica  flowers,  in  moderately  fine  powder,  24  troyounces. 
Alcohol,  4  pints. 
Water,  2  pints  
Diluted  alcohol  a  sufficient  quantity.
