444  Twenty-third  Annual  Meeting  of  the    {'^"^  JcT'is^s""'' 
The  paper  on  Iodoform,*'  by  H.  M.  Wilder,  of  Philadelphia,  re- 
commends Bouchardat's  process  as  easy  of  execution  and  giving  a  fair 
yield  ;  but  for  obtaining  the  largest  yield,  Filhol's  process  is  the  best. 
For  the  cleaning  of  mortars  and  other  utensils  in  which  iodoform  was 
used,  an  alcoholic  solution  of  potassa  or  soda  was  recomrnended  ;  or, 
if  this  did  not  fully  accomplish  the  purpose,  a  concentrated  solution  of 
bichromate  of  potassium  with  sulphuric  acid. 
For  Chlorodyne,  Mr.  J.  F.  Hancock  recommended  the  formula  of 
P.  Squire  {see  ''Amer.  Journ.  Pharm.,"  1870,  p.  263 — "  Proc.  Amer. 
Phar.  Assoc.,  1874,  p.  338),  and  that  it  be  perscribed  under  the  name 
of  "  Liquor  chloroformi  compositus,"  to  distinguish  it  from  the  nos- 
trum bearing  the  former  name. 
A  paper  on  Matico,"  by  the  Secretary,  stated  that  this  term  is  ap- 
plied in  South  America  to  various  plants,  the  leaves  of  which  possess 
vulnerary  properties  [%ee  "Amer.  Journ.  Pharm.,"  1875,  p.  118). 
Mr.  Wm.  Saunders,  of  London,  Ont.,  had  formerly  supposed  that 
the  insects  attacking  rhubarb  root  were  the  same  kind  usually  found  in 
drug  stores,  but  on  rearing  some,  he  had  found  it  to  be  a  different  spe- 
cies, which  was  new  to  him,  and  which  he  intended  to  investigate 
further. 
Prof.  E.  SchefFer  had  determined  by  his  experiments  that  pancreatin, 
when  brought  into  the  stomach,  became  destroyed,  and  consequeutly 
could  have  neither  physiological  nor  therapeutical  effect  when  taken 
internally. 
In  a  paper  on  "  The  action  of  nitric  upon  carbolic  acid,"  Prof.  G. 
C.  Wheeler  stated  that,  on  mixing  the  two  acids,  gases  are  rapidly  and 
violently  evolved,  projecting  the  mixture  in  all  directions,  and  that  this 
behavior  constitutes  the  so-called  explosions  which  have  been  noticed 
from  this  cause. 
Mr.  Jos.  Roberts  read  a  paper  on  "  Tests  for  chloralhydrate,"  sug- 
gesting to  estimate  the  chloroform  obtainable  by  decomposing  the  com- 
pound with  sodiumhydrate,  and  to  determine  the  formic  acid  by  volu- 
metric process. 
The  Secretary  spoke  of  the  traffic  in  patent  medicines,  to  which  the 
Association  is  opposed  ;  they  had  to  be  kept,  however,  in  most  stores, 
when  called  for,  and  the  efforts  of  pharmacists  to  diminish  this  trade 
would  amount  to  nothing  until  the  public  had  been  better  informed  of 
their  character  ;  he  then  referred  to  the  proposed  publication  of  the 
"Popular  Health  Almanac,"  Dr.  Fred.  Hoffmann,  editor,  as  one  of
