from  the  Lolium  perenne  while  the  plants  have  been  living.  The  infu- 
sion was  first  treated  by  the  ether  process  of  Stas.  On  the  evaporation 
of  the  ether  an  oily  residue  was  obtained  containing  a  minute  quantity 
of  a  resinous  substance.  The  extract  was  then  dissolved  in  alcohol, 
afterwards  mixed  with  water  and  filtered.  Chloriodide  of  mercury 
caused  a  precipitate  reminding  one  of  a  vegetable  alkaloid. 
I  did  not  detect  any  crystals  of  cholesterin  that  -are  said  to  exist  in 
Secale  cornutum,  but  phosphoric  acid  was  clearly  shown  by  using  molyb- 
date  of  ammonia  and  nitric  acid. 
In  toxicological  investigations  the  microscope  is  the  most  to  be 
depended  upon.  The  conidia  are  very  abundant  and  may  always  be 
detected  in  bread,  pastry  or  flour,  especially  if  acetic  or  chromic  acids 
be  used  to  make  their  presence  more  evident.  The  one-sixth  or  one- 
eighth  of  an  inch  is  a  sufficiently  high  power,  i  always  find  that  this 
mode  of  detection  is  preferable  to  the  use  of  potassa  and  distillation 
alone.  The  little  conidia  may  be  generally  observed  in  the  intestinal 
canal  of  a  poisoned  person  or  animal. — Pbar.  Jour,  and  Trans.,  Sept.

Improvement  in  Matches.  — Sudheim  and  Thoppen  manufacture  matches  which, 
they  claim,  are  neither  poisonous  nor  dangerous,  and  ignite  when  rubbed  on  any 
surface,  but  never  spontaneously.  They  are  made  by  first  dipping  the  wood  into  a 
mixture  prepared  by  triturating  together,  with  the  addition  of  a  little  water,  6  parts 
potassium  chlorate  and  3  parts  plastic  clay  (aluminium  silicate),  and  when  well 
mixed  adding  2  parts  red  lead,  some  glue  solution  (f  to  1  part  glue),  3  parts  pow- 
dered glass,  and  finally  1  part  red  phosphorus  ;  when  dry  the  half-finished  matches 
are  dipped  into  a  mixture  of  2  parts  sandarac,  10  parts  stearin  and  1  part  naph- 
thalin,  prepared  by  melting  together  the  sandarac  and  stearin  and  adding  the  naph- 
thalin.when  almost  cool. — Apoth.  Ztg.,  Aug.  .2,  1879,  P-  I27>  from  Ind.  BL 
Comparative  Antiseptic  Efficacy  of  Various  Acids  and  their  Salts. — N. 
Sieber's  researches  prove,  that  the  presence  of  0^5  per  cent,  acid  is  usually  suffi- 
cient to  prevent  decay.    The  mineral  acids  rank  first  in  regard  to  their  antiseptic
