Glycerite  of  Bismuth  is  best  prepared,  according  to  A.  Bareau,  by 
triturating  the  bismuth  salt  intimately  with  the  requisite  quantity  of 
starch  and  about  5  or  6  parts  of  water  and  adding  this  mixture,  with 
continual  agitation,  to  the  glycerin,  previously  heated  to  near  the 
boiling  point. — Union  Phar. 
Lac  Ossimn  is  prepared  by  saturating  somewhat  diluted  hydro- 
chloric acid,  by  digestion,  with  bones  burned  to  whiteness,  cooling,, 
filtering  and  evaporating  the  liquid  until  it  has  the  specific  gravity 
1*200.  Of  this  liquid  500  grams  are  diluted  with  6,000  grams  of 
distilled  water,  poured  into  a  cold  solution  of  330  grams  of  pure 
sodium  carbonate  in  6,000  grams  of  distilled  water,  and  the  precipi- 
tate is  washed  by  decantation  until  the  washings  cease  to  react  with 
nitrate  of  silver.  The  yield  is  3,000  grams.  It  is  important  that 
the  precipitation  be  effected  in  the  cold  and  from  a  strongly  diluted 
solution.— PAar.         No.  89,  1881;  Pliar  WeekbL 
Saccharated  Iodide  of  Iron,  according  to  A.  Jandous,  may  be 
rapidly  prepared  by  dissolving  iron  with  iodine  in  the  presence  of  50 
per  cent,  alcohol;  no  secondary  products  are  formed,  and  the  final 
exsiccation  is  accomplished  in  so  short  a  time  that  the  preparation  may 
be  almost  made  extemporaneously. — Phar.  Post,  No.  24,  1881. 
Tectrion  is  the  name  given  to  a  solution  of  magnesium  chloride, 
recommended  for  use  as  a  non-freezing  liquid.  It  is,  however,  not 
adapted  for  gas  meters,  since  it  corrodes  iron.  It  has  also  been-used 
for  increasing  the  weight  of  dyed  yarns.  In  1865  magnesium  chloride 
was  recommended  by  Dr.  A.  Frank  in  the  preparation  of  fire-brick 
for  puddling  furnaces. — Zeitsch.  Oest.  Ap.  Ver.,  1881,  p.  446. 
Preparation  of  Butter  of  Antimony. — Liquor  stibii  chlorati  of  the 
German  Pharmacopoeia  is  of  variabe  composition,  owing  to  the  impu- 
rities present  in  the  crude  material.  Prof.  E.  Reichardt  recommends 
the  following  process  for  its  preparation  :  1  part  of  powdered  sulphu- 
ret  of  antimony  is  mixed  in  a  capacious  flask  with  4  parts  of  crude 
hydrochloric  acid,  and  the  mixture  gradually  heated  to  boiling,  and 
until  sulphuretted  hydrogen  is  no  longer  evolved  in  the  presence  of 
undecomposed  black  antimony.  The  liquid  is  filtered,  diluted  with  6 
volumes  of  water,  the  preci[)itated  antimony  oxychloride  washed  upon 
a  filter  with  water  and  dried  between  20  and  30°C.    One  part  of  the
