form  all  condensation  should  take  place  in  the  condenser  and  none 
whatever  in  the  head,  therefore  the  head  should  be  small  and  near 
enough  to  the  source  of  heat  to  get  warm  and  thus  prevent  the 
loss  due  to  distilled  liquid  dropping  back  into  the  still  body.  By 
having  the  outlet  for  the  vapors  at  the  side  the  condensation  in  the 
top  of  the  Remington  still  is  almost  completely  obviated. 
These  stills  have  been  used  for  nearly  twenty-eight  years,  and  so 
far  very  little  chance  for  improvement  has  been  discovered.  In 
the  improved  still,  which  is  here  presented,  a  tight  joint  between 
the  still  top  and  body  is  made  by  tightening  up  the  thumbscrews, 
which  are  hinged  to  the  still  body.  When  the  still  is  to  be  put 
away,  the  unscrewing  of  these  bolts  quickly  effects  separation. 
As  the  condenser,  when  in  use  and  full  of  water,  is  rather  heavy, 
it  was  found  advisable  to  encircle  it  with  a  clamp,  which  is  capable 
of  being  adjusted  and  can  be  made  secure  at  any  point. 
These  are  the  only  improvements  that  have  been  made  in  this 
still  since  it  was  first  used.  The  rapidity  of  action  of  this  still 
seems  remarkable  and  only  serves  to  prove  the  principles  upon 
which  it  is  built  to  be  correct.  It  will  distil  two  gallons  of  diluted 
alcohol  per  hour,  or  one  gallon  of  water  per  hour,  using  the  heat  of 
an  ordinary  gas  stove.  It  is  made  of  tinned  copper  throughout,  so 
that  there  is  no  danger  of  rusting,  and  durability  is  secured. 
By  means  of  the  self-feeding  attachment  it  can  be  run  continu- 
ously, simply  requiring  to  be  looked  at  occasionally  to  see  that  the 
liquid  is  not  getting  too  low. 
MEMORIALS  TO  AMERICAN  PHARMACISTS.1 
By  Dr.  Fr.  Hoffmann. 
It  has  been  proposed  to  take  some  appropriate  action  in  com- 
memoration of  the  semi-centennial  anniversary  of  the  American 
Pharmaceutical  Association  at  the  occasion  of  its  fiftieth  annual 
meeting  to  be  held  in  Pniladelphia  in  1902.  Among  the  several 
practical  suggestions,  there  is,  in  the  first  place,  the  very  proper  one 
uf  having  elaborated  and  published  an  historical  sketch  of  the  asso- 
ciation, or  perhaps,  better,  of  American  pharmacy  and  the  rise  and
