addition  of  calcium  hypochlorite  solution  changes  the  red  into  a 
beautiful  green  color. — J.  Morpurgo,  Pharm.  Post,  1890,  258. 
Chloroform  in  ethyl  bromide. — In  the  preparation  of  the  latter 
chemical  from  potassium  bromide,  alcohol  and  sulphuric  acid,  the 
product  always  contains  ether  which  cannot  be  removed  in  the 
rectification,  and  which  will  give  a  preparation  of  low  specific 
gravity.  To  overcome  the  low  gravity  it  is  not  unlikely  that  chloro- 
form may  be  added  until  the  correct  gravity  is  obtained ;  such  an 
addition  could  only  be  detected  by  chemical  means,  and  here  the 
simplest  test  depends  upon  the  isonitril  reaction:  A  few  cc.  of  the 
sample  with  an  equal  volume  of  strong  sodium  or  potassium 
hydrate  solution  and  one  drop  of  aniline  are  agitated  in  a  test  tube; 
the  application  of  a  little  heat  should  develop  no  odor  differing 
from  the  cold  mixture.  Bromide  of  ethyl  with  1  per  cent,  of  chloro- 
form gave  immediately  the  offensive  odor  of  carbylamine.  This 
same  test  allows  of  the  ready  distinguishing  between  chloroform 
and  ethyl  bromide. — Dr.  L.  Scholvien,  Pharm.  Ztg.,  1890,  138. 
Boroglycenn-Cream — 10  boric  acid  is  dissolved  with  the  aid  of 
heat  in  24  0  glycerin  and  allowed  to  cool.  5-0  anhydrous  lanolin 
and  70-0  paraffin  ointment  are  melted  together,  colored  by  addition 
of  0  0 r  alkannin,  the  boroglycerin  added,  stirred  to  creamy  consist- 
ence and  perfumed  with  one  drop  each  of  oils  of  rose  and  bergamot. 
— E.  Dieterich,  Pharm.  Centralhalle,  1890,  158. 
Diachylon  Wound  Pozvder. — 5-0  lead  plaster  and  2-o  yellow  wax 
with  200  ether  are  agitated  in  a  flask  until  solution  or  perfect  dis- 
integration of  the  lead  plaster  results.  45  0  wheat  starch,  45-0 
talcum  and  3-0  boric  acid,  all  in  very  fine  powder,  are  mixed  in  a 
mortar,  then  the  ethereal  solution  added,  perfumed  with  one  drop 
each  of  the  oils  of  wintergreen  and  bergamot  and  exposed  on 
parchment  paper  at  ordinary  temperature  until  the  volatilization  of 
the  ether.  This  powder  is  valuable  as'a  dusting  powder  in  chafing, 
sore  feet,  etc. — E.  Dieterich,  Pharm.  Centralhalle,  1890,  158. 
Lanolin  Dusting  Powder. — 5-0  anhydrous  lanolin  are  dissolved  in 
20-0  ether  and  rubbed  up  with  45-0  wheat  starch;  by  exposure  the 
ether  is  allowed  to  evaporate.  2:o  powdered  boric  acid  and  50-0 
powdered  talc  are  mixed  with  the  lanolin  starch  powder  and  flavored 
by  the  addition  of  one  drop  each  of  oil  of  wintergreen  and  oleo- 
balsamic  mixture. — E.  Dieterich,  Pharm.  Centralhalle,  1890,  159. 
Syrup  of  Coffee. — 200-0  finely  ground  coffee  are  moistened  with
