ferric  chloride  or  an  excess  of  albumen,  it  is  constant  in  its  composi- 
tion as  regards  the  relation  of  albumen  to  iron. 
3.  The  dried  and  powdered  product  is  readily  dissolved  by  water. 
4.  Obtained  by  the  method  recommended,  it  contains  a  certain  per- 
centage of  common  salt,  the  presence  of  which,  however,  does  not 
interfere  with  its  solubility,  nor,  it  is  likely,  with  its  therapeutic  appli- 
cation. ^ 
5.  The  process  recommended  is  rapid,  and  conducted  under  condi- 
tions in  which  the  albumen  cannot  be  unfavorably  affected  by  exposure 
to  the  heat  of  summer;  and,  even  if  exposed  for  a  longer  period  than 
is  necessary,  the  presence  of  salt  is  calculated  to  prevent  the  changes 
to  which  albumen  or  its  compounds,  in  a  moist  condition,  are  subject. 
6.  The  albuminate  represents  about  5  per  cent,  of  ferric  oxide,  or 
10  per  cent,  of  ferric  chloride.

Emulsion  of  Codliver  Oil  and  Phosphate  of  Calcium. — The  following 
will  be  found  to  make  a  satisfactory  and  pleasant  preparation  :

Mix  phosphate  with  a  small  portion  of  the  water,  and  the  acid  in 
sufficient  quantity  to  dissolve,  filter  through  cotton  and  add  the  remain- 
der of  the  water.     Pour  into  this  an  excess  of  solution  of  ammonia, 
1  Dr.  Hager  recommends  for  his  preparation,  which  is  preliminarily  obtained 
essentially  like  mine,  that,  after  the  addition  of  solution  of  salt,  the  mixture  be 
diluted  with  a  considerable  quantity  of  water,  the  precipitate  collected,  and  washed 
with  water  so  as  to  remo've  the  salt  as  much  as  possible.  I  have  not  had  opportunity  to 
test  the  value  of  this  direction,  though  my  observations  lead  me  to  fear  that  the 
entire  precipitate  might  by  such  procedure  again  enter  solution.  Some  experiments 
made  within  tbe  last  few  days  show  that  a  considerable  quantity  of  the  salt  can  be 
removed  from  the  dry  powder  by  shaking  it  with  water  and  immediately  throwing 
the  mixture  on  a  filter.  The  larger  portion  of  the  liquid  passes  colorless,  and  con- 
'  . tains  much  salt  ;  but  the  residue  on  the  filter  very  soon  assumes  a  gelatinous  condi- 
tion, and  finally  dissolves.  It  is  my  opinion  that  the  larger  part  of  the  salt  may  be 
removed  from  the  moist  press-cake  by  immersing  it  in  water  until  it  begins  to  exer- 
•cise  solvent  action  on  the  albuminate,  then  removing  the  cake  and  drying.
