Paregoric. — A  correspondent  calls  attention  to  the  impropriety  of  many 
druggists  and  apothecaries  continuing  the  old  practice  of  using  liquorice 
and  other  coloring  substances  in  this  preparation.  The  constant  associa- 
tion of  paregoric  and  laudanum  in  the  medicine  closets,  renders  it  very 
desirable  that  they  should  differ  greatly  in  appearance,  to  avoid  their  unin- 
tentional substitution,  in  the  often  hasty  resort  that  is  had  to  them  at  night 
in  cases  of  sickness,  or  by  persons  unable  to  read. 
Hopkins'  Chalybeate  Water. — We  have  received  a  circular  in  regard 
to  this  new  mineral  water,  which  informs  that  the  Spring  is  located  about 
thirteen  miles  N.  E.  of  Baltimore.  Several  Baltimore  physicians  speak 
of  its  efficacy  as  a  chalybeate.  The  following  is  Prof.  Campbell  Morfit's 
analysis  : 
Chemical  Examination  of  Well   Water,  from  the  farm  of  William  Hopkins 
Esq.,  at  the  head  of  Saltpetre  Creek,  Baltimore  County,  Maryland.  Specific 
Gravity,  1.0003.

A  portion  of  the  Carbonic  Acid  is  in  a  gaseous,  absolutely  free  state  and 
the  Water  is  therefore  a  mildly  acidulous  Carbonated  Chalybeate.

Philadelphia  College  of  Pharmacy. — The  lectures  in  the  School  of 
this  College,  open  by  a  general  introductory  by  Prof.  Procter,  on  Monday

Dr.  Wells,  the  Discoverer  of  Anaesthesia. — We  have  received  a 
pamphlet  with  the  above  title,  containing  the  fac  simile  of  a  letter  from  the 
widow  of  Dr.  Wells,  claiming  for  her  late  husband  the  honor  of  the  dis- 
covery of  anaesthesia,  in  opposition  to  the  claims  of  Dr.  Morton  &c.  It 
is  greatly  to  be  regretted  that  this  valuable  discovery  should  be  the  subject 
of  so  much  wrangling  and  ill  feeling.  Where  an  idea  is  gradually  developed 
through  the  action  of  several  minds,  and  important  results  afterwards 
flow  from  it,  it  is  natural  that  each  participant  in  the  labor  should  institute 
a  claim.  This  affair  reminds  us  of  the  composition  of  water  controversy 
in  which  the  claims  of  Cavendish,  Watt  and  Lavoisier  were  brought  in  con- 
flict
