dental  to  travelling  hundreds  of  miles,  vanish  under  such  circumstances,  and 
nothing  remains  but  the  pleasure  and  the  profit  we  derive  from  the  surround- 
ings and  the  animated  company  in  which  we  move,  until  we  return  to  our 
home,  when  a  day  or  two  of  rest  will  be  welcome  to  us. 
Need  we  say  anything  of  Cleveland,  the  point  to  which  we  were  bound  ?  The 
Association  went  there  a  stranger,  none  of  its  living  members  had  ever  at- 
tended a  meeting ;  but  true  hospitality  made  every  visitor  soon  feel  at  home 
there,  and  we  should  not  be  surprised  if  the  results  of  this  meeting  should  far 
surpass  the  anticipations. 
Let  it  be  likewise  next  year,  in  Richmond,  Va.

Detection  of  Sulphuric  A  cid  in  Vinegar. — In  the  April  number  of  this 
Journal  we  published  a  paper  on  this  subject,  by  Mr.  James  T.  King,  which 
has  been  criticised  by  Dr.  P.  H.  Vander  Weyde,  in  the  following  communica- 
tion to  the  Scientific  American  of  August  31st : 
"  The  method  to  detect  the  sulphuric  acid  cheat  in  vinegar,  given  by  the 
American  Journal  of  Pharmacy  and  republished  in  your  paper  on  page  120,  is 
the  most  glaring  piece  of  stupidity  which  I  have  had  the  misfortune  to  encoun- 
ter for  a  long  time,  and  the  editors  of  the  American  Journal  of  Pharmacy 
should  know  better  than  to  publish  such  nonsense.  You  are  perfectly  right  in 
wishing  that  some  of  your  readers  might  suggest  an  easier  method  for  this  pur- 
pose. 
44  The  addition  of  the  alcohol  is  not  made  in  order  to  take  up  1  the  free  sul- 
phuric acid  to  the  exclusion  of  the  sulphates,'  as  the  druggist's  circular  states, 
but  to  destroy  the  acetic  acid  by  changing  it  into  acetic  ether  ;  the  mixture  of 
acetic  acid,  alcohol,  and  sulphuric  acid,  and  afterwards  evaporating  or  distill- 
ing the  same,  is  exactly  the  regular  method  for  making  the  volatile  acetic 
ether,  which  will  be  the  vapor  or  the  product  of  the  distillation  ;  in  this  way 
the  acetic  acid  is  disposed  of  with  the  alcohol,  and  the  free  sulphuric  acid  and 
the  sulphates  are  left;  pure  vinegar  must  neither  contain  the  one  nor  the  other, 
and  if  adulterated  with  sulphuric  acid,  it  will  mostly  contain  traces  of  sulphates 
also.    The  addition  of  a  solution  of  chloride  of  barium  will,  in  any  vinegar,
