either  wliollj  or  in  part.  From  tlie  roots  proper,  tlie  lec- 
tures will  proceed  to  consider  tlie  underground  stems,  rH- 
zomeS;  bulbs,  corms  and  tubers,  then  tbe  overground  stems  and 
woods,  the  barks,  whetber  obtained  from  root  or  trunk,  then 
the  herbs  and  leaves,  including  those  herbaceous  drugs  which 
are  usually  found  in  commerce,  containing  all  the  organs  re- 
quisite for  establishing,  by  botanical  analysis,  their  true  origin. 
These  will  be  followed  by  the  drugs  consisting  of  flowers  or 
parts  of  flowers,  then  by  the  fruits  proper,  and  finally  the 
seeds. 
The  products  obtained  from  plants  in  various  ways  will  next 
claim  attention,  and  will  be  considered  in  groups,  based  on 
their  physical  appearance  and  chemical  constitution,  and  em- 
bracing morbid  excrescenses  and  exudations,  volatile  oils,  fixed 
oils,,  resins,  oleo-resins,  gum-resins,  starches,  &c. 
The  consideration  of  the  drugs  of  animal  origin  will  conclude 
the  course. 
This  course  will  aim  mainly  to  present  to  the  student  the 
m'eans  and  leading  characteristics  for  recognizing  each  indi- 
vidual drug,  and  distinguishing  it  from  all  others ;  the  physical 
characters  of  the  drugs,  their  structure  and  their  chemical  re- 
lations will,  therefore,  occupy  most  of  the  time  allotted  to  the 
course,  since  by  these  means  recognition  can  be  effected  and 
substitutions  or  adulterations  discovered.  The  botanical  and 
commercial  history  of  the  drugs  will  receive  their  full  share  of 
attention,  as  will  also  the  important  proximate  principles  upon 
which  the  medicinal  virtues  of  the  drugs  depend  or  are  sup- 
posed to  depend;  a  concise  view  will  also  be  given  of  the 
medical  properties,  the  officinal  preparations,  and  the  doses  of 
the  same. 
The  drugs  derived  from  the  animal  kingdom  will  be 
arranged  and  treated  of  upon  the  same  principles  and  in  a 
similar  manner  as  those  of  vegetable  origin. 
The  extensive  cabinet  and  herbarium  belonging  to  the  Col- 
lege, as  also  the  private  collection  of  the  Professor,  in  addition 
to  well  executed  plates  and  drawings,  will  furnish  ample  means 
of  illustration,  and,  wherever  it  is  deemed  necessary,  experi- 
ments will  be  made  in  proof  of  the  facts  stated.
