volatile  impurities  probably  rise  in  the  early  part  of  the  process,  they  can 
be  separated  by  fractioning  the  products  and  rejecting  the  first  portions. 
The  immense  amount  of  glycerin  that  is  thrown  away  in  the  soap  waste  of 
the  soap  boiler  must  be  rendered  available  by  a  process  capable  of  separa- 
ting the  volatile  as  well  as  fixed  impurities  from  the  glycerin  it  contains, 
before  the  latter  can  be  produced  at  a  low  price.  Hennell  Stevens  &  Co., 
of  Philada.,  have  so  far  perfected  a  process  of  this  kind  as  to  produce 
glycerin  almost  tasteless  and  odorless  from  the  concentrated  fetid  liquors  of 
the  soap  maker,  by  apparatus  involving  the  distillation  of  the  glycerin. 
They  have  exhibited  to  us  specimens  of  this  glycerin,  nearly  equal  to  that 
of  Price  &  Co.,  and  with  a  little  more  experience  with  the  process  it  is  quite 
probable  that  they  can  get  it  to  produce  uniform  results.  The  glycerin 
na  it  flows  from  the  still  has  the  sp.  gr.  of  1-25  and  possesses  but  little  color, 
Tartro-citrate  or  Soda. — Mr.  D.  S.  Dyson,  of  Washington,  D.  C,  has 
called  our  attention  to  the  "Tartro  citric  Lemonade,"  of  T.  E.  Jenkins  &  Co. 
of  Louisville,  Kentucky,  who  propose  it  as  a  substitute  for  Citrate  of  Magnesia. 
We  have  had  a  bottle  in  possession  for  nearly  four  months,  which  has 
undergone  no  apparent  change.  It  is  a  solution  of  tartrate  of  soda,  sac- 
nharized  and  acidulated  with  citric  acid.  It  has  an  agreeable  taste,  is  pos- 
sessed of  about  the  same  activity  as  the  citrate  of  magnesia,  and  possesses 
the  merit  of  being  less  expensive  to  make.  Mr.  Dyson  was  not  aware  of 
the  proportion  of  tartrate  of  soda  present,  but  we  presume  that  six  drachms 
of  tartaric  acid  properly  saturated  with  bicarbonate  of  soda,  and  rendered 
agreeable  with  lemon  syrup,  and  afterwards  citric  acid  and  bicarbonate  of 
soda  to  generate  sufficient  carbonic  acid  and  leave  the  preparation  agreeably 
acid  would  yield  a  good  preparation.  We  have  had  the  preparation  tried, 
and  find  it  possessed  of  the  same  degrees  of  activity  as  the  Citrate  of  Mag- 
nesia, with  about  as  little  taste.  As  it  is  cheaper  than  the  citrate,  it  may 
be  substituted  for  that  preparation,  if  found  on  more  extensive  trial  to  equal 
it  in  efficiency.  Messrs.  T.  E.  Jenkins  So  Co.  vend  large  quantities  in 
Louisville. 
New  Edition  of  Latin  Pharmaceutical  Labels,  published  by  authority 
of  the  Philadelphia  College  of  Pharmacy.  The  Latin  Label  Committee 
have  just  published  two  new  books  of  Labels  for  the  shop  furniture  of 
Apothecaries  and  Druggists,  and  another  of  smaller  size  for  physicians7 
>rders,  and  other  uses  where  correct  labels  are  desirable.  Of  the  two 
former  books,  one  is  executed  in  black  letter  on  yellow  paper,  with  forms 
similar  to  the  last  bronze  edition.  The  other  is  printed  entirely  from 
engraved  plates,  and  presents  a  bronze  ground  with  steel  blue  letters  and 
outlines,  which  render  it  by  far  the  most  elegant  edition  yet  published,  and 
the  best  substitute  for  the  artists'  pencil  yet  published  in  this  country. 
At  the  request  of  the  Committee  we  have  attached  specimens  of  the  labels 
to  the  advertising  sheet  of  this  number,  which  contains  an  advertisement 
referring  to  them.
