Didlisis  Quimica.    Aplicaciones  del  Sulfato  de  Cat.    Por  Alfonso  D.  Her-

Chemical  Dialysis.    Applications  of  Calcium  Sulphate. 
The  author  has  made  a  study  of  the  process  of  dialysis  and  of  the  application 
of  various  chemicals,  having  much  affinity  for  water,  for  the  concentration  of 
liquids  without  evaporation.  For  the  latter  purpose  anhydrous  sulphate  of 
calcium  was  found  to  be  well  adapted.  After  the  requisite  quantity  of  plaster 
Paris  has  been  added,  the  mixture  is  well  agitated  for  fifteen  or  twenty 
minutes,  when  the  hydratedsalt  is  deposited  as  a  crystalline  powder,  from  which* 
most  of  the  liquid  can  be  readily  poured  off,  the  small  quantity  retained  by  the 
powder  being  recovered  by  forcible  expression  or  by  centrifugal  force.  A  little 
calcium  sulphate  remaining  dissolved  in  the  aqueous  filtrate,  is  either  precipi- 
tated by  alcohol,  or  the  calcium  is  removed  by  sodium  carbonate.  The  author 
makes  also  suggestions  for  the  use  of  this  method  in  the  preparation  of  various 
organic  compounds,  of  galenical  preparations,  and  in  analytical  investigations.
