evaporate  the  liquids  to  the  consistency  of  extract ;  redissolve  this  in 
16  times  its  weight  of  cold  water;  filter  and  add  7J  ounces  by  weight 
of  glycerin  to  each  pound  of  opium  employed,  and  evaporate  to  15 
ounces. 
I  have  had  this  preparation  on  hand  two  years  and  a  half,  in  good 
condition.  Two  pounds  of  good  opium  have  always  given  me  15  oz. 
of  extract. 
The  soda  ley  for  making  san  ton  ate  of  soda  (see  Amer.  Jour.  Pharm.

Sinalbin.  O30  H44  N2  S2  016,  according  to  H.  Will,  is  a  glucoside, 
extracted  by  alcohol  from  yellow  mustard.  An  aqueous  infusion  of 
mustard  decomposes  this  body  into  sulfocyanacrylin  (C8  H7  NSO), 
acid  sulphate  of  sinapirin  (C16  H]9  NS09)  and  sugar  (C6  H12  09).  Ether 
dissolves  only  sulfocyanacrylin,  which  is  an  acrid  oil  insoluble  in 
water  and  not  volatile.  Sinalbin  yields  with  nitrate  of  silver  a  white 
precipitate,  from  which  sulphuretted  hydrogen  liberates  cyanacrylin 
C8  H7  NO,  soluble  in  water,  alcohol  and  ether,  and  fusible  at  69°  C- 
Boiled  with  potassa,  ammonia  is  evolved,  and  an  acid  C8  H8  03  which 
fuses  at  136°  C. 
The  author  does  not  state  the  relation  of  these  bodies  to  the  com- 
pounds which  have  been  thus  far  assumed  to  be  derived  from  yellow 
mustard. — Pharm.  Zeitschr.  f.  Mussl.,  1871,  595,  from  Zeitschr.  f.

Antidote  to  Carbolic  Acid.  Dr.  Theodore  Husemann  opposes  the 
use  of  fixed  oils,  glycerin  and  similar  demulcents  in  cases  of  poison- 
ing by  carbolic  ;  but  recommends,  based  upon  experiments  with  rab- 
bits made  by  himself  and  Ummethun,  the  saccharate  of  lime,  the  alka- 
line earth  combining  with  the  carbolic  acid  to  form  a  non-poisonous 
salt.  Lime  water  is  less  adapted  to  this  purpose,  owing  to  the  spar- 
ing solubility  of  lime  in  water,  and  the  large  quantity  of  lime  water 
required  for  neutralizing  the  poison.  Precipitated  carbonate  of  lime 
does  not  combine  with  carbolic  acid,  but  may  be  employed  in  case  the 
saccharate  of  lime  should  not  be  procurable  at  once ;  the  carbonate
