of  lime,  and  then  yields  with  ammonia  and  sulphate  of  magnesia  a 
precipitate  of  ammonio-phosphate  of  magnesia.  The  solution  of  the 
grape-wine  precipitate  separates  by  an  oxalate  a  little  oxalate  of  lime, 
and  then  precipitates,  on  supersaturation  with  ammonia,  all  the 
phosphoric  acid  as  magnesia  salt,  so  that  a  solution  of  magnesia  will 
not  disturb  the  clear  liquid.    One  litre  cider  (from  pears)  yielded 
0-  369  P05,  the  same  quantity  of  Neckar  wine  0-366  P05.  The  au- 
thor found  also  that  hi3  grape-wines  naturally  contain  malic  acid. 
One  litre  Malaga  wine  yielded  0*640  P05.  Further  experiments  with 
fruit-  and  grape-wines  of  an  undoubted  purity  are  very  desirable. 
Pure  Soda  hydrate  by  Crystallization. — This  process,  proposed  by 
O.  Hermes,  has  been  tried  by  Klas  Lindroth,  who  observed  that  a 
very  impure  solution  of  soda  of  specific  gravity  1-215  would  not  crys- 
tallize at  a  temperature  of — 22°  C.  ( — 17°  F.),  but  crystallized  read- 
ily after  concentration  to  1-375  spec.  grav.  After  draining  the  crys- 
tals in  a  well-covered  glass  funnel,  they  were  found  to  contain  mere 
traces  of  carbonate  and  chloride. — N.  Jahrh.f  Pharm.,  1871,  from

A  new  delicate  test  for  Ammonia  has  been  observed  by  Lex.  Liquids 
containing  minute  quantities  of  ammonia  assume  a  green  color  when 
treated  with  carbolic  acid  and  afterwards  with  chlorinated  lime. —

Collodium  Cotton  and  Creasote. — According  to  Wirth,  coilodium 
cotton  yields  with  beechwood  tar-creasote  a  clear  liquid,  which,  at  first 
thick,  soon  becomes  limpid  and  homogeneous.  Coal  tar-creasote 
yields,  after  continued  agitation  with  the  cotton,  a  gelatinous  and,  for 
the  greater  part,  consistent  mass. — Ibid.,  from  Pharm.  Ztg. 
Testing  Balsam  of  Peru. — This  balsam  has  a  specific  gravity  of 
1-  140  to  1*160,  and  therefore  sinks  if  added  to  a  solution  of  one  part 
of  table  salt  in  four  of  water,  which  has  a  specific  gravity  of  1-125. 
The  addition  of  even  a  small  quantity  of  a  fixed  oil  to  balsam  of  Peru 
renders  it  lighter. — Ibid.,  from  Apoth.  Ztg. 
Galega  officinalis,  for  improving  the  secretion  of  milk,  was  recom- 
mended by  Gilles  and  Langenhagen.  Dr.  Oeffinger  has  used  it  in 
the  form  of  syrup  with  good  success,  and  reports  that  not  only  the 
quantity  of  the  milk  is  increased,  but  that  it  is  likewise  improved  in 
quality.    In  one  case  the  milk  consisted  before  the  treatment  of  92-4
