appearance  of  a  yellowish  or  reddish  color  indicates  an  excess  of  cor- 
rosive sublimate.  Sufficient  of  the  albumen  solution  is  now  added 
until  the  precipitate  by  carbonate  of  sodium  has  a  purely  white  color. 
The  amount  of  chloride  of  sodium  necessary  for  affecting  a  permanent 
solution  is  now  ascertained  by  adding  sufficient  of  its  aqueous  solution 
until  merely  a  faint  cloudiness  remains.  From  the  figures  thus  obtained 
the  necessary  proportions  are  readily  calculated.  The  mixture  is  set 
aside  for  two  days,  then  filtered  and  kept  in  small  well-corked  vials  in 
a  cool  place.  The  solution  is  made  to  contain  i  per  cent,  of  mercury 
albuminate,  when  iocc.  will  yield  0*171  sulphide  of  mercury. — Zeitscbr.

Solution  of  Ammonium  Acetate. — J.  C.  Thresh  purchased  seven  sam- 
ples, only  two  of  which  were  colorless  aud  had  a  neutral  reaction. 
They  varied  in  specific  gravity  between  i*ou  and  1*018  and  the  per- 
centage of  ammonium  acetate  between  4*6  and  7*9. — Pharm.  your, 
and  Trans.,  1876,  April  1,  p.  781. 
Glycerol  of  Subacetate  of  Lead  is  recommended  by  Balmanno  Squire 
as  a  very  useful  application  in  chronic  eczema  and  other  skin  diseases. 
It  is  prepared  of  the  same  strength  as  the  liquor  plumbi  subacetatis,  sub- 
stituting glycerin  for  the  water.  The  heating  is  effected  in  an  oil  bath, 
care  being  taken  to  keep  the  temperature  a  little  below  the  boiling 
point  of  glycerin,  and  when  the  reaction  has  been  accomplished,  the 
solution  is  to  be  filtered  while  hot,  since  after  cooling  it  is  too  viscid 
to  pass  through  the  filter.  For  use  it  is  diluted  with  from  three  to 
seven  times  its  quantity  of  glycerin,  as  occasion  requires.— Pbar.  Jour, 
and  Trans.,  May  6,  p.  881. 
C.  D.  Parry  proposes  to  mix  equal  measures  of  liquor  plumbi  suba- 
cetatis and  glycerin  and  to  evaporate  by  gentle  heat  until  the  water  is 
driven  off.— Ibid.,  May  27,  p.  942. 
Phosphorus  Pills. — Messrs.  Allen  and  Hanburys  suggest  the  follow- 
ing formula  as  an  efficient  sustitute  for  that  of  the  British  "  Pharmaco- 
poeia," which  combines  the  phosphorus  with  tolu  balsam  and  yellow 
wax  :  2  grains  of  phosphorus  dissolved  in  sufficient  bisulphide  of  car- 
bon, are  mixed  with  powdered  soap  and  guaiac  resin,  of  each  gr.  xxxv, 
glycerin  gtt.  xii  and  powdered  liquorice  rootgr.  xii  or  sufficient  to  make 
a  mass  weighing  gr.  c.  The  bisulphide  evaporates  readily,  and  the 
mass  formed  is  of  good  consistence,  easily  manipulated,  readily  misci-
