A*mri,im*'}  Minutes  of  Pharmaceutical  Meetings.  565 
mirabile  Schott.  et  Endl.  Also,  Carpotroche  Brasiliensis  Endl.  The  meeting 
desired  the  expression  of  thanks  for  these  additions  to  the  library  of  the  Col- 
lege. 
Prof.  Maisch  also  presented,  from  Mr.  P.  W.  Bedford,  a  map  locating 
the  various  articles  of  "  Materia  Medica.'?  The  map,  though  generally  correct, 
has  in  several  instances  mistaken  the  locality  of  some  of  our  American  plants^ 
The  work  is  a  very  valuable  one  to  the  student  of  materia  medica  and  phar- 
macy, and  supplies  a  want  long  felt* 
Mr.  Remington  presented  a  modified  form  of  crystallized  permanganate  of 
potassa,  in  which  the  ordinary  needle-like  character  was  entirely  wanting,  the 
crystals  merely  showing  the  pyramidal  summit  common  to  the  usual  salt.  This 
•effect  was  doubtless  due  to  interference  from  other  salts  of  greater  solubility 
present  in  the  solution  from  which  the  permanganate  was  crystallized.  The 
appearance  of  the  modified  form  of  crystals  was  such  as  to  lead  to  the  suppo- 
sition that  an  adulteration  was  attempted.  The  article  was  imported  from 
Germany  and  offered  for  sale  in  this  market. 
Prof.  Maisch  introduced  the  subject  of  musk,  and  exhibited  several  very 
interesting  samples  of  the  pod,  obtained  from  Mr.  Cramer,  who  imported  the 
pods.  Among  the  collection  were  some  curiously  shaped  pods,  which  had  been 
pressed  in  a  conical  shape  in  drying  or  during  transportation,  also  some  with 
-exceedingly  thick  skins. 
From  the  records  kept  by  Messrs.  Cramer  and  Small,  the  following  has  been 
furnished  to  show  the  yield  of  musk  :

Prof.  Maisch  also  exhibited  a  mass  of  cubical  crystals,  which  were  found  on 
the  coast  of  Patagonia,  embedded  in  guano.  Analyzed  at  the  College  labora- 
tory, by  Mr.  N.  J.  Bayard,  they  were  found  to  be  chloride  of  ammonium. 
Prof.  Maisch  exhibited  the  leaves  of  Eucalyptus  globulus,  recently  highly 
recommended  in  Europe  in  fevers  ;  also,  a  specimen  of  the  volatile  oil.  The 
tree  is  indigenous  to  Australia,  and  is  of  rapid  growth,  attaining  the  height  of 
300  feet.  In  Europe  this  tree  is  used  as  an  ornamental  tree  for  shade,  and  was 
supposed  to  have  a  good  effect  on  the  salubrity  of  the  climate. 
Prof.  Maisch,  on  behalf  of  E.  H.  Heinitsh,  of  South  Carolina,  exhibited  a 
sample  of  South  Carolina  opium.  It  is  considered  by  those  engaged  in  pro- 
ducing opium  in  this  State  that  the  plants  can  be  grown  with  considerable 
profit.  The  sample  sent  has  not  yet  been  analyzed  ;  it  was  gathered  when  the 
plant  was  green  and  in  its  luxuriance  of  growth.
