particularly  beneficial  in  cases  of  delirium  tremens,  or  in  the  insomnia 
resulting  from  intense  cental  labor  or  excitement. 
Thus,  I  gave  a  gentleman,  who,  owing  to  business  anxieties,  had 
not  slept  for  several  nights,  and  who  was  in  a  state  of  great  excite- 
ment, a  single  dose  of  thirty  grains.  He  soon  fell  into  a  sound 
sleep,  which  lasted  for  seven  hours.  The  next  night,  as  he  was 
wakeful,  I  gave  him  a  like  dose  of  bromide  of  potassium,  but  it  was 
without  effect,  and  he  remained  awake  the  whole  night.  The  subse- 
quent night  he  was  as  indisposed  to  sleep  as  he  ever  had  been,  but  a 
dose  of  thirty  grains  of  bromide  of  calcium  gave  him  eight  hours 
sound  sleep,  and  he  awoke  refreshed  and  with  all  unpleasant  cerebral 
symptoms — pain,  vertigo,  and  confusion  of  ideas — entirely  gone. 
In  a  number  of  other  instances  a  single  dose  has  sufficed  to  induce 
sleep,  a  result  which  very  rarely  follows  the  administration  of  one 
dose  of  any  of  the  other  bromides. 
In  those  exhausted  conditions  of  the  nervous  system  attended  with 
great  irritability,  such  as  are  frequently  met  with  in  hysterical 
women,  and  which  are  indicated  by  headache,  vertigo,  insomnia,  and 
a  mental  condition  of  extreme  excitement,  bromide  of  calcium  has 
proved  in  my  hands  of  decided  service.  Combined  with  the  syrup 
of  the  lacto-phosphate  of  lime,  it  scarcely  leaves  anything  to  be  de- 
sired. An  eligible  formula  is — 1^.  Calcii  bromidi  si,  syrup,  lact. 
phos.  calc.  giv.  M.  ft.  sol.  Dose,  a  teaspoonful  three  times  a  day 
in  a  little  water. 
In  epilepsy  I  have  thus  far  seen  no  reason  for  preferring  it  to  the 
bromide  of  potassium  or  sodium,  except  in  those  cases  in  which  the 
paroxysms  are  very  frequent,  or  in  cases  occurring  in  very  young  in- 
fants ;  of  these  latter,  several,  which  had  previously  resisted  the 
bromide  of  potassium,  have  yielded  to  the  bromide  of  calcium.  It 
does  not  appear  to  cause  acne  to  anything  like  the  extent  of  the 
bromide  of  potassium  or  of  sodium. 
My  object  in  writing  this  note  is  simply  to  call  attention  to  a 
remedy  which  promises  well. — New  York  Medical  Journal,  December,

ber 1st,  1871,  Mr.  John  Elliot  Howard  read  a  paper,  in  which  he  re- 
corded his  latest  experiments  on  the  Indian  Cinchonas.
