AUTOMATIC  WATER  STILL. 
By  F.  J.  Stokes. 
Several  papers  have  been  published  in  the  American  Journal 
OF  Pharmacy  on  desirable  forms  of  stills  for  pharmaceutical  pur- 
poses. 
Professor  Procter  described  a  still  for.  apothecaries  in  the 
American  Journal  of  Pharmacy  for  January,  1864,  p.  12.  This 
still  was  a  modification  of  the  apparatus  described  by  him  in  1848 
in  the  American  edition  of  Mohr  and  Redwood's  Pharmacy.  In 
the  same  issue  (page  22)  Mr.  Wiegand  described  a  still  which 
was  primarily  used  to  recover  alcohol  from  various  preparations. 
Somewhat  later  Neynaber  (Amer.  Jour.  Pharm.,  1865,  p.  166} 
described  an  automatic  pharmaceutical  still  in  which  a  continuous 
distillation  was  affected.  Pharmacists,  generally,  are  familiar  with 
the  distillatory  apparatus  devised  by  Professor  Remington  (see  this 
Journal,  1878,  p.  15;    1879,  P-  225). 
Without  entering  into  a  description  of  the  various  forms  of 
stills  which  have  already  been  devised,  I  shall  consider  a  new  and 
inexpensive  automatic  water  still  which  is  of  interest  to  every 
druggist  as  it  produces  distilled  water  at  the  remarkably  low  cost 
of  one  cent  per  gallon  per  hour.  It  is  gas  heated  and  being- 
automatic  requires  no  attention.  It  is  fastened  to  the  wall  and 
gas  and  water  connections  can  be  made  with  rubber  tubing.
