precipitation  of  phosphoric  by  molybdic  acid  ;  oxalate  and  citrate  of 
ammonia  exert  this  injurious  influence  in  such  a  degree  that  they 
will  prevent  the  precipitation  altogether,  if  present  in  sufficient  quan- 
tity.— Zeitschr.  f.  anal.  Chem.,  1871,  3,  305—307. 
Colored  sulphate  of  atropia  has  been  observed  by  Dr.  H.  Hager, 
who  attributes  the  coloration  to  the  presence  of  a  glucoside.  The 
solution  boiled  with  nitrate  of  silver  became  colored  and  separated 
black  metallic  silver ;  boiled  with  an  alkaline  solution  of  copper, 
cuprous  oxide  was  deposited.  The  author  regards  all  sulphate  of 
atropia  as  impure  and  unfit  for  medicinal  use,  which  acts  upon  the 
two  solutions  mentioned. — Pharm.  Cent.  Halle,  1871,  Oct.,  26. 
Lead  in  phosphate  of  lime. — Mr.  Duquesnel  has  often  found  com- 
mercial phosphate  of  lime  to  contain  small  quantities,  about  one-half 
per  cent.,  of  the  insoluble  oxychloride  of  lead.  Its  presence  is  ex- 
plained by  the  use,  in  chemical  factories,  of  lead  vessels  for  dissolv- 
ing the  calcined  bones  in  muriatic  acid.  The  lead  is  readily  detected 
by  the  black  precipitate  occurring  with  sulphuretted  hydrogen  in  a 
solution  of  the  phosphate  in  muriatic  acid. — Journ.  de  Ph.  et  de  Chim.

A  new  method  for  preparing  Bland's  pills. — Mr.  J.  F.  Michiels 
recommends  the  following  process  for  obtaining  a  pill  mass  of  good 
consistence  and  keeping  well ;  it  has  the  advantage  of  not  requiring 
any  inert  powder,  although  it  is  slightly  hygrometric.  500  grm.  pow- 
dered sulphate  of  iron  and  the  same  quantity  of  powdered  carbonate 
of  potassa  are  intimately  mixed ;  60  grm.  of  powdered  white  sugar 
are  added ;  the  mixture  is  heated  in  an  iron  mortar,  with  constant  tri- 
turation, until  a  sufficient  amount  of  water  of  crystallization  has  been 
expelled,  and  a  convenient  pill  mass  obtained.* — Bullet,  de  la  Soc.
