tion  during  my  analysis,  and  the  tests  Nos.  3,  4,  and  5  in  my 
analysis  were  suggested  by  him. 
Conclusions. 
1.  The  bean  is  edible  in  poisonous  quantities,  and  although 
slightly  rough  in  its  flavor,  does  not  appear  to  excite  disgust 
or  alarm  when  eaten  alone,  and  would  be  undiscovered  when 
mixed  with  food. 
2.  The  symptoms  are  not  always  immediate,  nor  is  vomiting 
induced,  except  when  the  dose  is  excessive  ;  nor  would  the 
secondary  symptoms,  viz.,  dizziness,  faintness,  and  loss  of  power 
in  the  limbs,  excite  sufficient  alarm  to  call  for  medical  assistance 
until  life  was  really  in  immediate  danger. 
3.  The  symptoms  would  scarcely  be  distinguished  from  sud- 
den indigestion  or  English  cholera  in  time  to  save  the  life  of 
the  patient. 
4.  In  criminal  cases,  nothing  might  be  detected  by  autopsy 
or  by  chemical  analysis  to  reveal  the  cause  of  death. 
5.  So  insidious  a  poison  should  not  only  be  stored,  but  also 
handled  with  great  caution  ;  its  alcoholic  solutions  or  extractive, 
0  when  introduced  into  the  circulation,  acting  as  a  slow  but  certain 
poison,  leaving  no  trace  in  the  body  which  can  be  identified  by 
chemical  tests  in  our  present  knowledge  of  the  poison. — Lond.

MANUFACTURE  OF  VEGETABLE  OILS. 
Whether  considered  as  a  medium  for  the  application  of 
color  in  works  of  art,  or  of  utility  as  the  principal  source 
of  illuminating  power  where  gas  is  unattainable,  or  as  the 
lubricator  without  which  all  machinery,  from  the  simple  clock 
of  the  cottager  to  the  most  complicated  and  powerful  engine, 
would  be  all  but  useless,  the  value  of  oil  is  incalculable ;  and  a 
few  words  on  its  manufacture  and  the  process  of  refining  it 
cannot  be  uninteresting.  To  furnish  these  we  were  favored 
with  a  visit  to  the  extensive  works  of  Messrs.  Pinchin  and 
Johnson,  who  have  two  sets  of  premises:  one,  for  the  manufac- 
ture of  oil,  called  AlberrWorks,  on  the  Middlesex  bank  of  the 
Thames,  near  Hammersmith ;  the  other,  for  refining  purposes,
