well  cared  for.  It  should  be  thoroughly  cleansed  after  each  filtra- 
tion by  removing  the  distance  frames  with  their  accumulation  of 
precipitate  and  pumping  water  through  the  press.  The  cloths  should 
be  washed  in'hot  water  with  the  addition  of  appropriate  chemicals 
if  necessary.  The  papers  will  serve  for  but  one  nitration  and  should 
be  thrown  away  at  its  conclusion.  When  heavy  precipitates  have 
been  filtered  out  the  pump  should  be  taken  apart  and  cleaned,  the 
connecting  pipes,  safety  tube  and  air  chamber  should  receive  the 
same  treatment.  This  must  be  done  shortly  after  the  filtration  for 
pharmaceuticals  soon  dry  onto  iron  and  the  masses  adhere  so  tena- 
ciously as  to  make  the  cleaning  a  matter  of  considerable  labor. 
In  all  cases  it  must  be  remembered  that  the  filter  press  is  a  deli- 
cate piece  of  apparatus  and  demands  careful  attention  to  produce 
the  best  results.  We  believe  that  it  has  a  place  in  pharmaceutical 
manufacturing  which  cannot  be  taken  by  any  other  filtering  process 
in  use  at  the  present  time.  It  may  be  difficult  to  adjust  it  to  suit 
some  certain  condition  sometimes,  but  it  always  amply  repays  the 
labor  spent  upon  it.  It  is  substantial  and  less  liable  to  serious  injury 
than  most  pharmaceutical  apparatus.  The  products  filtered  through 
it  are  as  elegant  in  appearance  and  as  stable  as  the  best.  Its  use 
indicates  a  distinct  advance  in  pharmaceutical  manipulation.

THE  TEXTBOOK  AND  THE  COLLEGE. 
Dean  Lucius  E.  Sayre,  University  of  Kansas  School  of  Pharmacy. 
Dean  Lucius  E.  Sayre,  of  the  college  of  pharmacy  of  the  Uni- 
versity of  Kansas,  visited  the  University  of  Minnesota  during  the 
week  of  October  23.  On  Thursday  morning  he  was  introduced  to 
the  students  of  the  college  of  pharmacy  by  Dean  Wulling  and  de- 
livered a  most  interesting  address.  In  introducing  Professor  Sayre, 
Dean  Wulling  stated  that  the  college  of  pharmacy  of  the  University 
of  Minnesota  had  contemplated  for  many  years  the  securing  of 
prominent  pharmacists  in  both  this  country  and  abroad  for  special 
lectures  and  that  while  not  as  many  such  speakers  had  been  ob- 
tained as  the  college  had  hoped  for,  yet  some  of  exceptional  note 
had  already  lectured,  and  that  others  would  probably  be  secured  in
