are  continual  vomiting  and  hiccough,  the  appearance  of  red  spots  in 
the  face  and  diminution  of  the  number  of  heart-beats.  In  one  case 
death  followed  in  four  days.  Stimulants  and  morphine  are  recom- 
mended as  antidotes. — Journ.  de  Pharm.  Gkim.  ;  Archiv.  June,  1885. 
By-product  in  bread  baking. — Experiments  reported  by  R.  K.  for 
the  recovery  of  the  alcohol  eliminated  by  the  baking  process  gave  the 
following  result:  On  baking  3  kilos  of  dough  150  Gm.  of  distillate 
of  0'9801  sp.  gr.  were  obtained,  equal  to  spirit  of  13  per  cent,  or  15'6 
grams  of  alcohol.  Supposing  that  the  oven  be  used  four  times  a  day 
for  baking  50  loaves  of  bread,  weighing  2  kilos  each,  the  liquid  con- 
densed by  means  of  suitable  arrangements  during  a  year,  would  con- 
tain 730  liters  of  alcohol. — Schweiz.  W.f.  Ph.,  No.  24,  1885. 
Paraldehyde  as  an  antidote  to  Sti-ychnine  is  recommended  by  Prof. 
Arpad  Bokai,  Cervello  and  Dujardin-Beaumetz.  Bokai  also  found  it 
valuable  as  a  counter-poison  to  brucine,  thebaine,  picrotoxin. — Chem.

Preparation  of  Cocaine. — Trupheme  recommends  exhausting  the 
coca  leaves  with  ether,  distilling  the  ether,  treating  the  remainder  with 
boiling  water,  mixing  with  magnesia  and  drying.  The  powder  thus 
obtained  is  exhausted  with  amylic  alcohol  which  yields  the  cocaine 
somewhat  yellowish;  by  recrystallization  it  is  obtained  colorless. —

Cotton  Seed. — Sacc  has  communicated  to  the  Acad.  d.  Sciences  an 
analysis  of  the  press  cake  of  cotton  seed,  which  contains  casein  6*0, 
dextrin  0'2,  sugar  2*0,  fibrin  23*7,  woody  tissue  32*1,  starch  9*6,  green- 
ish yellow  oil  9*6,  yellow  wax  0*8,  water  8'0,  and  ash  8*0.  On  grind- 
ing, 56"5  of  yellowish  meal  and  40*5  of  black  bran  Avere  obtained. 
The  author  regards  the  meal  as  being  of  value  in  bread  baking  for 
taking  the  place  of  milk,  and  in  the  refining  of  sugar  for  removing 
excess  of  lime. — Archiv  d  Phar.,  June,  1885,  p.  453. 
Fstimation  of  Casein  in  Milk. — Frenzel  and  Weil  recommend  diluted 
sulphuric  acid  in  place  of  acetic  acid  for  precipitation.  In  a  beaker 
glass  of  1 50  cc.  capacity,  place  60  cc.  distilled  water,  add  20  cc.  of  well- 
shaken  milk  by  means  of  a  pipette  and  stir  well.  Then  add  30  cc. 
dilute  sulphuric  acid  (1 : 1000),  put  in  a  cool  place  for  several  hours, 
pass  the  supernatant  liquid  through  a  weighed  filter,  collect  the  pre- 
cipitate upon  the  same  filter,  wash  twice  with  water,  and  afterwards 
successively  with  90  per  cent,  alcohol,  absolute  alcohol  and  ether.
