the  precipitate  was  then  treated  with  acetic  acid,  and  the  filtered  Hquid 
neutralized  by  ammonia.  The  precipitate  was  then  washed  with  water, 
suspended  in  alcohol  and  decomposed  by  sulphuretted  hydrogen.  On 
evaporating  the  filtrate,  tannic  acid  was  obtained,  giving  a  dark-green 
color  to  ferric  salts. 
Treatment  with  Cold  Water, — The  substance,  after  having  been 
exhausted  with  ether  and  alcohol,  was  dried,  and  macerated  with  cold 
water  for  four  days,  and  strained  ;  a  turbid  liquid,  of  a  light-brown 
color,  having  a  slight  acid  reaction,  was  obtained.  Much  albumen  was. 
separated  by  heat ;  the  concentrated  filtrate  yielded  with  alcohol  a  floc- 
culent  precipitate  of  gum,  which  was  soluble  in  water  and  precipitated' 
from  this  solution  by  acetate  and  subacetate  of  lead. 
Treatment  with  Boiling  Water. — The  substance,  after  being  exhausted 
with  cold  water,  was  next  treated  with  boiling  water,  the  liquid  strained 
and  evaporated  to  half  its  bulk  ;  on  cooling,  it  deposited  a  brown,  jelly- 
like substance,  which  was  insoluble  in  cold  water,  and  is  probably 
pectin.  A  small  portion  of  the  filtered  liquid,  treated  with  iodine^ 
resumed  a  distinct  blue  color,  proving  the  presence  of  starch. 
The  remaining  portion  of  the  liquid  was  again  concentrated  to  a  small 
bulk,  and  proved  to  be  free  from  glucose.  The  green  portion  of  the 
stipes  treated  in  the  manner  described  above,  gave  similar  results,  but 
yielded  a  larger  amount  of  resin,  and  are,  perhaps,  as  efficient  as  the 
rhizomes. 
The  oleo-resin  compared  favorably  with  the  best  German  oleo-resin 
of  male-fern  I  could  get  in  the  city,  so  far  as  could  be  judged  by  the 
appearance,  taste  and  odor.  Samples  of  it  have  been  placed  into  the 
hands  of  a  prominent  physician  in  this  city,  who  promised  to  closely 
watch  its  eff'ect,  and  report  the  result.

ON  GLYCONATED  EMULSION  OF  COD  LIVER  OIL. 
BY  T.  D.  m'ELHENIE,  PH.  G. 
The  writer  desires  to  call  the  attention  of  the  profession  to  a  new 
combination  of  this  valuable  agent.  The  formula,  somewhat  modified, 
is  that  proposed  by  Dr.  Geo.  M.  Beard  in  the  "Archives  of  Elcctrology 
and  Neurology  "  for  May,  1874.  I  have  prepared  the  emulsion  frequently 
for  Dr.  Bartlett,  of  this  place,  who  esteems  it  highly  as  a  brain  and
