tion  that  there  exists  some  new  relation  between  these  coloring 
matters.  The  substance  which  Czumpelick  obtained  by  the 
treatment  of  aloin  with  dilute  acids  concurs  so  closely  in  its 
properties  with  rottlerin,  that  there  seems  to  exist  little  cause  to 
doubt  their  identity.  Stenhouse's  formula  for  aloin  is  perfectly 
in  accordance  with  the  supposition  that  in  be'ng  spi  t  it  forms 
rottlerin  and  sugar,  taking  up  the  elements  of  water,  viz.

In  this  connection,  it  is  of  interest  to  notice  that  the  ru'gative 
principle  of  aloes  contains  a  substance  homologous  w  th  one  of 
the  proximate  principles  of  rhubarb. —  Drug.  Circ,  from  S/czungs-

ON  THE   PRESERVATION1   OF  ANIMAL  MATTERS  IN  THE 
OPEN  AIR. 
By  ML.  Pagliari. 
I  ha  ve  the  honor  to  communicate  to  the  Academy  (of  Sciefie^B 
at  PurLi),  a  new  and  very  simple  mo  le  of  preserving  animal 
matter.  The  liquor  which  I  employ  for  this  purpose,  is  com- 
posed of  alum,  benzoin  and  water,  and  differs  but  little  from  my 
haemostatic  water.  A  single  coat  of  this  preserving  liquid  applied 
upon  the  substance  which  is  then  exposed  to  the  open  air,  is 
sufficient  to  prevent  its  dec  iy. — Journal  Franklin  lnstitu  et

[Pagliari's  haemostatic  water  is  made  by  boiling  for  six  hours  8  ounces 
of  Tincture  of  Benzoin  containing  about  2  ounces  of  the  Balsam)  a  pound 
of  alum,  and  ten  pounds  of  water,  in  a  glazed  earthen  vessel,  stirring 
constantly,  and  supplying  the  loss  with  hot  water.  The  liquor  is  then 
strained  and  bottled.— Ed. Am.  Jour.  Pharm.]
