PHYSIOLOGICAL  PROPERTIES  OF  ORGANIC  RADICALS.  31 
The  apparatus  I  have  found  most  convenient  for  containing 
and  preserving  standard  solutions,  and  more  particularly  solutions 
of  ammonia,  consists  of  a  vessel  similar  to  a  wash-bottle,  to  which 
is  attached  an  India  rubber  bulb ;  so  that  when  it  is  desired  to 
fill  the  burette,  it  is  only  necessary  to  compress  the  bulb.  This 
arrangement  affords  great  facility  for  replenishing  the  burette  ; 
and  by  placing  a  piece  of  India  rubber  tubing,  closed  at  one  end, 
on  the  jet,  an  air-tight  reservoir  for  the  solution  is  obtained

ON  THE  PHYSIOLOGTCAL  PROPERTIES  OF  SOME  OF  THE  COM- 
POUNDS OF  THE  ORGANIC  RADICALS,  METHYLE,  ETHYLE, 
AND  AMYLE.  By  James  Turnbull?  Esq.,  Physician  to  the  Liverpool 
Royal  Infirmary. 
He  had  examined  two  compounds  of  methyle — the  acetate  of 
the  oxide  of  methyle,  and  the  iodide  of  methyle  ;  four  of  ethyle 
— the  acetate  of  the  oxide  of  -ethyle,  the  iodide  of  ethyle,  the 
bromide  of  ethyle,  and  the  cyanide  of  ethyle  ;  two  of  amyle — the 
acetate  of  the  oxide  of  amyle,  and  the  iodide  of  amyle.  The 
acetate  of  the  oxide  of  methyle  acted  as  a  diffusible  stimulant, 
and  checked  expectoration — a  property  common  to  most  of  the 
methyle,  ethyle,  and  amyle  compounds.  The  iodide  of  methyle 
produced  all  the  physiological  effects  of  iodine,  and  might  be 
detected  in  the  saliva  and  urine  in  half  an  hour  after  it  had  been 
swallowed.  He  had  used  it  as  an  external  remedy  in  scrofulous 
ulcers  with  advantage,  and  he  had  used  it  for  inhalation  in  pul- 
monary diseases,  to  promote  the  healing  of  ulcers  of  the  lungs  ; 
but  for  the  latter  purpose  he  had  found  another  preparation,  the 
iodide  of  ethyle,  more  serviceable.  The  iodide  of  ethyle  he  had 
found  a  warm  stimulating  remedy,  which  produced  the  physiolo- 
gical effects  of  iodine,  too,  but  was  less  stimulating.  It  acted  as 
a  powerful  anesthetic  when  inhaled,  and  he  had  ascertained 
that  the  injurious  effects  which  Mr.  Nunnery  had  observed  from 
it  had  arisen  from  his  having  used  an  impure  compound  conta- 
minated with  phosphorus.  He  had  used  it  internally  in  scrofu- 
lous diseases  with  advantage,  and  as  its  odor  was  perceived  in 
the  breath  there  seemed  to  be  a  special  tendency  to  the  elimina- 
tion of  this  and  other  ethyle  compounds  through  the  lungs.  As
