now  numbers  more  than  seven  hundred  members  in  all  parts  of  our  coun- 
try, and  representatives  from  all  sections  will  be  in  attendance.  We 
hope  to  see  many  faces  from  south  of  the  Potomac  come  to  join  hands  in 
this  truly  national  society  of  pharmaceutists. 
In  relation  to  the  contributions  to  the  building  fund,  the  Treasurer  of 
the  Building  Committee  has  furnished  a  list  which  will  be  found  at  page 
376,  and  we  hope  it  will  induce  many  others  to  extend  their  aid  in  season. 
Dr.  Robley  Dunglison,  so  long  and  favorably  known  as  a  teacher  and 
writer  of  medicine,  has  resigned  the  chair  of  Physiology  in  the  Jefferson 
College,  and  the  vacancy  thus  created  has  been  filled  by  the  election  of 
Dr.  John  Aitken  Meigs,  of  Philadelphia.  Although  not  personally  ac- 
quainted with  Dr.  JVleigs,  we  are  informed  by  those  who  are  that  the 
choice  of  the  Trustees  is  emiuently  judicious. 
Erratum. — In  the  notice  of  William  Herapath  in  our  May  number,  we 
inadvertently  attributed  to  him  the  discovery  of  iodosulphate  of  quinia, 
which  was  made  by  his  son,  Dr.  William  A.  Herapath,  also  a  chemist.

Again  this  little  annual  presents  itself  for  notice.  It  is  the  twenty- 
eighth  of  the  series,  and  consists  of  extracts  from  the  periodical  literature 
of  medicine  and  pharmacy  during  1867,  principally  continental.  The  vol- 
ume for  1866  was  translated  and  published  last  year,  and  we  presume  this 
also  will  be  rendered.  The  articles  of  interest  under  the  head  of  narcot- 
ics, anaesthetics,  stimulants,  alteratives  and  revulsives  are  numerous,  but 
we  have  only  space  to  offer  an  extract  from  one  of  the  latter.  M.  Rigol- 
let,  in  speaking  of  his  mustard  paper,  (sinapisme  en  feuilles)  and  refer- 
ring to  its  advantages  in  avoiding  the  use  of  linen  and  the  inconveniences 
of  preparing  an  ordinary  poultice,  says  : 
"  On  a  sheet  of  paper  of  a  certain  firmness,  1  fix  a  layer  of  flour  of  Al- 
sace mustard  one  millimetre  (one-thirteenth  of  an  inch)  thick.  It  was 
not  difficult  to  imitate  the  industrial  process  for  the  manufacture  of  glass 
paper  or  velvety  wall  paper,  in  which  glass  powder  or  cloth  nap  are  held 
on  the  surface  by  a  layer  of  glue.  But  it  was  necessary  to  find  a  viscous 
liquid  which  contained  neither  wa^er,  alcohol  or  resinous  matter  to  bind 
the  mustard.  Water  wonld  develop  the  essential  oil  ;  alcohol  coagulate 
the  myrosine,  and  stop  the  production  of  volatile  oil,  whilst  the  fatty  bo- 
dies would  prevent  the  action  of  water  on  the  mustard  to  develop  its 
power."  "Only  one  substance  has  succeeded;  this  is  caoutchouc  dis- 
solved in  bisulphuret  of  carbon  or  a  volatile  oil.  Before  the  operation 
the  solvent  evaporates  and  leaves  the  mustard  meal  imprisoned  in  a  net- 
work of  fibres  adhering  to  the  paper,  and  which  are  as  permeable  by  water 
as  the  meshes  of  a  seive.    This  sheet  of  paper,  thus  prepared,  becomes
