silver,  gold,  platinum,  &c.  Under  eacli  metal  will  be  introduced 
their  compounds  witli  non-metallic  elements  and  their  inorganic 
salts,  with  their  pharmaceutic  relations  and  preparations  in  the 
United  States  and  British  Pharmacopoeias. 
Organic  chemistry  will  conclude  the  course.  In  this  will  be 
considered  all  those  compounds  of  general  or  pharmaceutical 
interest,  which  are  not  included  in  the  other  branches  of  instruc- 
tion, without  any  aim  at  special  classification ;  comprising 
those  which  are  either  natural  products  or  are  the  results  of 
spontaneous  change  or  decomposition  by  heat  alone,  or  with 
alkalies  and  the  action  of  non-metallic  elements,  acids,  &c. 
Commercial  impurities  (whether  of  design  or  accident)  will 
receive  due  attention,  and  their  character  and  means  of  detec- 
tion will  be  pointed  out. 
In  connection  with  all  articles  of  an  active  character,  their 
toxicological  relations  will  be  given,  together  with  their  anti- 
dotes and  methods  of  detection. 
Every  article  noticed  will  be  exhibited  both  in  the  crude 
a,nd  perfect  state,  and  processes  for  their  production,  formation 
and  purification  detailed,  and,  when  practicable,  shown. 
In  all  cases  illustrations  by  experiment  will  be  introduced, 
in  proof  of  the  assertions  or  facts,  and  by  diagrams,  to  convey 
the  fundamental  principles  of  the  science,  and  thus  more 
strongly  impress  the  learner's  mind.

This  course  will  open  with  a  lecture  on  the  proper  time  and 
best  mode  of  collecting  and  preserving  the  various  substances 
of  vegetable  and  animal  origin  used  in  medicine.  The  drugs 
will  then  be  considered  in  a  systematic  manner,  so  as  to  bring 
those  together  which  resemble  each  other  in  their  physical 
properties  and  structure. 
The  drugs  of  vegetable  origin  will  be  treated  of  in  accord- 
ance with  the  different  organs  of  plants  of  which  they  consist,
