and  the  cases  were  described  in  detail  by  the  author.  He  arrived  at 
the  conclusion  that  "  the  administration  of  ozonized  oils  has  a  re- 
markable tendency  to  reduce  the  frequency  of  the  pulse."  He  goes 
on  to  say :  "  If  ozonized  oil  can  reduce  the  rapidity  of  the  circula- 
tion— a  feature  of  great  prominence  in  phthisis — this  remedy  pos- 
sesses a  most  valuable  property,  rendered  still  more  valuable  by  its 
contributing  at  the  same  time  to  improve  the  general  health."  The 
author  makes  a  special  point  of  having  used  ozonized  oil  of  turpen- 
tine with  marked  and  prompt  advantage  in  some  cases  of  haemoptysis. 
In  the  same  journal,  same  year,  p.  330,  Dr.  E.  Symes  Thompson, 
son  of  the  doctor  quoted  above,  gives  the  results  of  some  experiments 
of  the  effect  produced  on  the  pulse  by  use  of  ozonized  oils.  He  re- 
cords the  cases  of  seventy  patients  to  whom  ozonized  oils  were  admin- 
istered with  good  effect.  He  draws  special  attention  to  the  impor- 
tance of  these  experiments  in  their  relation  to  the  treatment  of 
phthisis,  since,  as  he  says,  "  anything  that  could  retard  the  excessive 
rapidity  of  the  vital  changes  would  likewise  check  the  development 
and  progress  of  the  disease." 
He  mentions  several  remedies  that  had  been  used  to  this  end,  all 
greatly  inferior  to  the  ozonides,  for  those,  unlike  the  other  remedies  in 
their  action,  also  did  not  exert  a  depressing  influence  on  the  health,  but 
rather  a  strengthening  and  invigorating  one.  The  author  also  alludes 
to  a  paper  published  in  i860  by  a  French  physician  "  On  the  Use  of 
Ozonized  Oil  of  Turpentine  in  Haemoptysis,"  in  which  the  sugges- 
tions made  by  his  father  in  1859  had  been  followed  with  good  results. 
In  a  letter  to  the  London  Medical  Times  and  Gazette,  1875,  vol.  1, 
p.  25  and  following,  Dr.  Thomas  Wood,  of  Wilmington,  N.  C,  says : 
"  I  would  like  to  make  a  remark  upon  the  influence  which  the  turpen- 
tine distilleries  have  upon  the  town  in  which  I  live.  Wilmington, 
N.  C,  the  town  spoken  of,  is  the  great  export  market  for  oil  or  spirits 
of  turpentine.  .  .  .  During  the  late  Civil  War  all  the  turpentine  dis- 
tilleries were  closed  and  not  put  into  operation  again  until  from  1866 
to  1870. 
"  It  had  long  been  a  popular  theory  that  the  health  of  the  com- 
munity was  due  to  the  resiniferous  odors  from  these  stills,  and  this 
opinion  was  shared  by  medical  men  also.  In  1862,  after  the  ceasing 
of  the  operations  of  these  distilleries,  a  violent  epidemic  of  yellow 
fever  broke  out.  .  .  .  True  to  the  theory  as  to  the  health-giving 
virtues  of  the  resin  and  other  products  of  the  pine  tree,  barrels  of 
resin  were  burned  day  and  night  in  the  streets.   The  only  other  nota-
