dered  the  calomel  soluble,  while  the  liquid  from  the  first  (a)  was  unaffected  by 
the  gas.  This  experiment  has  served  to  remove  much  of  the  difficulty  previ- 
ously felt  of  accounting  for  the  effect  of  a  salt  insoluble  in  acid,  and  is  of  value 
as  showing  why  calomel  does  not  produce  its  characteristic  effects  in  cholera 
and  other  conditions  in  which  the  digestive  powers  are  in  abeyance,  or  when 
the  active  ingredients  of  the  gastric  juice  are  wanting. — Nashville  Journ.  of

Celery  as  a  Nervine. — A  correspondent  of  the  "Practical  Farmer"  says 
(Med.  Bulletin,  Cincinnati  Med.  Repertory),  "  I  have  known  as  many  men,  and 
women  too,  who,  from  various  causes,  had  become  so  much  affected  with  ner- 
vousness that  when  they  stretched  out  their  hands  they  shook  like  aspen  leaves 
on  windy  days ;  and  by  a  daily  moderate  use  of  the  blanched  foot  stalks  of  the 
celery  leaves  as  a  salad,  they  became  as  strong  and  steady  in  limbs  as  other 
people.  I  have  known  others  so  very  nervous  that  the  least  annoyance  put 
them  in  a  state  of  agitation,  and  they  were  in  almost  constant  perplexity  and 
fear,  who  were  effectually  cured  by  a  daily  moderate  use  of  blanched  celery  as 
a  salad  at  meal  times.  I  have  known  others  cured  by  using  celery  for  palpita- 
tion of  the  heart. —  Georgia  Medical  Companion,  June,  1872,  from  Med.  Cos~
