grm.  of  creasote  to  150  grms.  of  cod  liver  oil.  He  also  recommends  a  wine  of 
creasote  made  by  dissolving  6  grms.  of  creasote  in  125  grms.  of  alcohol,  and  adding 
400  grms.  of  simple  syrup  and  sufficient  Malaga  wine  to  make  1  liter.  This  is 
weaker,  but  preferable  to  that  made  by  Bouchard's  formula,  which  contains  in  the 
same  measure  135  grms.  of  creasote  and  30  grms.  of  tincture  of  gentian,  but  no 
syrup. — Rep.  de  Phar.,  1878,  p.  98. 
Oil  of  rose  geranium,  Pelargonium  rosatum,  according  to  Jaillard,  is  freely  solu- 
uble  in  70  per  cent,  alcohol.  Since  the  fixed  and  most  volatile  oils  which  may  be  used 
for  adulteration  are  sparingly  soluble  in  that  liquid,  they  may  be  readily  detected  by 
mixing  in  a  test  tube  6  drops  of  the  suspected  oil  with  5  cubic  centimeters  of  70 
per  cent,  alcohol.  After  agitation  the  solution  must  be  complete. — Jour,  de  Phar.  et

To  Detect  Cotton  Fibre  in  Linen. — The  fabric  is  well  washed,  dipped  into  an 
alcoholic  solution  of  rosolic  acid,  known  in  commerce  as  aurin  or  yellow  corallin, 
afterwards  immersed  in  a  concentrated  aqueous  solution  of  sodium  carbonate  and 
finally  washed ;  the  linen  fibre  is  dyed  rose-red  by  this  treatment,  while  cotton 
remains  white. — Phar.  Zeitung,  No.  18 — Polyt.  Notizbl. 
Impressions  from  Plants. — A  piece  of  paper  is  saturated  with  oil,  folded  to  4. 
thicknesses  and  subjected  to  great  pressure  to  facilitate  the  uniform  absorption  of 
the  oil.  The  plant  or  leaf  is  now  placed  between  the  oiled  paper,  moderately 
pressed,  then  removed  to  clean  paper  and  again  pressed.  This  last  paper  is  after- 
wards dusted  over  with  finely  powdered  plumbago  or,  better  still,  with  a  mixture  of 
rosin  and  plumbago  5  on  warming  the  paper  with  the  adhering  latter  admixture  a 
permanent  impression  is  obtained. — Apotheker.  Zeit.,  No.  9 — Industriebl. 
MINUTES  OF  THE  PHARMACEUTICAL  MEETING. 
Philadelphia,  April  16,  1878. 
In  the  absence  of  the  President,  Mr.  Wm.  Mclntyre  was  called  to  the  chair  $ 
the  minutes  of  the  last  meeting  were  read  and  approved.  Prof.  Maisch  corrected  a 
statement  he  had  made  at  the  last  meeting  in  regard  to  the  tincture  of  protochloride 
of  iron,  and  said  that  it  was  made  officinal  in  the  German  Pharmacopoeia  of  1872* 
and  prepared  by  dissolving  25  parts  of  the  recently  prepared  protochloride  of  iron 
in  225  parts  of  diluted  alcohol  (sp.  gr.  0-892),  adding  1  part  of  pure  hydrochloric 
acid,  and  filtering. 
Prof.  Maisch  presented  from  Dr.  F.  V.  Greene,  U.  S.  N.,  a  specimen  of  oil  of 
Tucuma  (from  the  Astrocavyum  tucuma),  also  a  specimen  of  the  oil  of  Batiputa 
(Gomphia  parviflora,  Mart.),  both  from  Brazil.  The  former  appears  not  to  be 
employed  medicinally,  but  the  fruit  is  eaten  by  the  Indians,  and  the  fibres  of  the 
plant  possess  great  tenacity.  The  latter  is  used  in  place  of  olive  oil  and  medicinally 
as  an  embrocation  in  rheumatism  and  erysipelas.
