Tincture  of  Kino. 
79 
Five  pints  each  of  each  tincture  of  kino  and  of  catechu  were  made  in 
June,  1878  ;  at  this  date  there  is  no  precipitation  or  gelatinization  of 
what  is  left,  about  a  pint  in  each  bottle,  and  the  preparations  are  just  as 
reliable  to-day  as  they  were  then. 
Therapeutically,  there  can  be  no  objection  to  the  use  of  a  small 
quantity  of  logwood  entering  the  preparation,  as  it  has  likewise  astrin- 
gent properties. 
The  formula  is  as  follows  :  Take  of  kino  three  troyounces,  logwood 
half  a  troyounce,  diluted  alcohol  a  sufficient  quantity.  Reduce  the 
kino  and  logwood  to  coarse  powder,  and  prepare  in  the  usual  way  by 
percolation.

Additional  Remarks  by  the  Editor.- — At  the  last  meeting  of 
theaBritish  Pharmaceutical  Conference,  Mr.  B.  H.  Bamford  read  a 
paper  on  the  same  subject,  recording  his  observation  with  a  tincture 
which  had  been  purchased  from  a  London  drug  house  between  1862 
and  1864,  and  since  that  time  had  been  kept  in  a  partly  filled  bottle 
covered  with  blue  paper,  and  dusted  and  shaken  every  morning ; 
although  over  fifteen  years  old  the  tincture  did  not  gelatinize,  and  the 
remedv  proposed  against  the  trouble  was  daily  agitation  and  a  cover  of 
blue  paper. 
From  the  subsequent  discussion  we  make  a  few  brief  abstracts.  Mr. 
Martindale  was  of  opinion  that  much  depended  on  the  age,  and  in  the 
opinion  of  Mr.  Umney  on  the  source  of  the  kino  used.  Mr.  T.  F. 
Abraham  had  never  seen  the  tincture  gelatinize  during  fifteen  years  ; 
Mr.  Preston  had  used  the  tincture  for  seventeen,  and  Mr.  Hasselby  for 
twenty-five  years,  and  both  noticed  only  one  case  of  gelatinization. 
Only  one  instance  was  also  observed  by  Mr.  Robbins  and  by  Dr. 
Symes.  Messrs.  Ellinor  and  Savage  had  known  the  tincture  prepared 
by  one  establishment  to  gelatinize,  and  made  by  others  to  remain 
liquid  ;  the  latter  had  been  exposed  to  the  light.  The  use  of  glycerin 
for  its  preservation  was  also  alluded  to,  but  it  remained  to  be  proved 
whether  the  addition  affected  prejudicially  the  astringency  of  the  tinc- 
ture. 
These  are  the  observations.  As  to  the  remedy,  it  was  the  opinion  of 
the  President,  Mr.  Schacht,  that  it  lay  not  so  much  in  the  management 
of  the  preparation  as  in  the  selection  of  the  material  of  which  it  was
