ounces,  repeated  twice  or  three  times  in  the  course  of  the  day. 
It  may  in  some  instances  be  advantageously  conjoined  with  salts 
of  iron  or  of  mercury,  with  both  of  which  it  is  compatible.  The 
addition  of  a  little  syrup  of  orange  peel  and  comppound  tinc- 
ture of  cardamom  forms  a  draught  by  no  means  disagreeable. 
Conclusion. 
This  article  furnishes  a  key  in  part  to  the  subject  under  con- 
sideration, though  it  is  not  quite  so  conclusive  as  it  could  be 
desired.  That  the  bark  is  the  same  as  that  which  Dr.  Ure 
speaks  of  does  not  admit  of  a  doubt,  but  whether  it  is  positively 
the  malambo  matias  or  not  remains  to  be  determined,  but  yet 
wTe  have  every  reason  to  believe  that  it  is  so.  Owing  to  the  fact 
that  no  botanical  history  of  the  tree  furnishing  this  bark  could 
be  found  anywhere,  which  I  regret  exceedingly,  the  true  name 
of  the  bark  could  not  be  satisfactorily  settled.  It  is  evident 
from  these  sensible  properties  that  it  possesses  valuable  medicinal 
qualities,  combining,  as  it  does,  the  agreeable  aromatic  with 
the  powerful  bitter  properties.  It  is  to  be  hoped  that  physi- 
cians and  others  having  it  in  their  power,  will  take  hold  of 
this  bark  and  test  its  remedial  powers,  and  give  it  such  a 
place  in  the  materia  medica  as  its  merits  may  justify. 
EE  MARKS  ON  CHLORINE  WATER. 
By  Dr.  Edward  Stieron",  Tarentum,  Alleghany  County,  Penna. 
The  editors  of  the  Dispensatory  of  the  United  States  (10th 
edition,  Philadelphia,  1854),  have  given  two  different  methods 
of  preparing  chlorine  water,  one  is  called  the  Dublin,  the  other 
the  Edinburgh  method. 
According  to  the  Dublin  method,  chlorine  gas  is  expelled  from 
a  mixture  of  peroxide  of  manganese  and  muriatic  acid,  and  the 
gas  absorbed  by  a  certain  quantity  of  distilled  water ;  according 
to  the  Edinburgh  method,  certain  quantities  of  chloride  of  so- 
dium, of  red  oxide  of  lead,  of  sulphuric  acid,  and  of  water  are 
put  in  a  bottle  with  a  glass  stopper,  and  occasionally  shaken. 
Then,  after  the  red  color  shall  have  changed  almost  white,  the 
insoluble  matter  will  be  allowed  to  subside  before  using  the 
liquid. 
By  the  Dublin  method,  the  true  and  pure  solution  of  chlo-
