are  now  being  made  to  induce  the  lime  and  lemon  growers  of  the  South  to  prepare 
the  lime  juice,  and,  if  this  should  prove  successful, — there  being  no  reason  why  it 
should  not — the  entire  production  and  manufacture  of  citric  acid  will  be  kept  in  the 
country,  saving  hundreds  of  thousands  of  dollars  annually,  and  developing  another 
great  industry. 
Borax  was  formerly  imported  from  England  and  Europe  at  the  rate  of  from  600,- 
000  to  1,000,000  pounds  every  year  ;  now  it  has  largely  fallen  off,  owing  to  the  devel- 
opment of  the  borax  mines  in  Nevada,  and  only  such  qualities  are  imported  as  may 
be  needed  to  make  up  for  any  temporary  deficiency  in  the  American  supply.  The 
importation  of  borax  during  the  last  fiscal  year  at  this  port  was  only  3,492  pounds, 
and  the  price  of  the  refined  article,  which  is  now  prepared  in  this  city,  is  only  from 
8  to  9  cents  per  pound,  where  formerly  it  was  35  cents.  Instead  of  importing  borax, 
the  last  statistics  show  that  out  of  a  native  product  of  about  6,000,000  annually, 
over  2,000,000  pounds  are  exported  to  foreign  countries,  and  over  3,000,000  pounds 
are  used  in  manufactures  in  this  country  5  England  being  now  among  the  buyers, 
where  formerly  she  was  the  principal  seller  of  both  the  crude  and  refined  production.

Paris  bronzing  varnish  is  a  simple  solution  of  shellac  and  a  little  camphor  in 
alcohol.  1  part  shellac  dissolved  in  8  to  10  parts  alcohol,  and  mixed  with  \  part 
camphor,  triturated  with  a  little  lavender  oil,  yields  a  varnish  which  greatly  resem- 
bles the  commercial  article. — Pharm.  HandelsbL,  July  2,  1879,  p.  27. 
Adhesive  composition  for  preparing  sticky  fly-paper  is  made  by  Nessler  by 
melting  together  1  pound  white  rosin  and  1  pound  rapeseed  oil,  or  any  other  non- 
drying  oil  (American  manufacturers  preferably  use  castor  oil),  and  allowing  the 
mixture  to  cool. 
Another  good  formula  suggests  to  melt  together  1  pound  white  rosin,  350  grams 
lard  and  330  grams  oil. 
Brumata-glue  is  a  similar  mixture,  and  said  to  consist  of  Venice  turpentine  and 
a  little  expressed  oil  of  laurel. —  Pharm.  Ztg.,  July  19,  1879,  P-  441* 
Quebracho  bark  has  lately  attracted  some  attention  in  Germany,  and  the  "Ber- 
liner Klinische  Wochenschrift"  contains  an  article  on  the  subject,  communicated  by 
Dr.  Penzoldt,  Quebracho  bark  is  obtained  in  Brazil,  and  probably  in  other  South 
American  states,  from  a  tree  belonging  to  the  Apocynaceae,  Aspidosperma  quebracho. 
The  bark  was  sent  to  Prof.  A.  Baeyer  for  the  purpose  of  separating  the  alkaloid,  in 
which  he  'succeeded,  calling  it  aspidospermina.  A  sample  of  the  bark  was  given 
to  Dr.  Penzoldt  to  experiment  and  establish  its  therapeutical  properties.   In  its  native
