*Mi!tmTM}  Pancreatic  Emulsions  of  Solid  Fats.  107 
before  th^y  were  written,  I  have  spent  much  time  in  endeavoring  to 
prepare  a  perfect  emulsion  of  solid  fat  which  would  keep  without  be- 
coming oxidized  and  at  the  same  time  form  a  preparation  which  would 
mot  offend  the  most  delicate  palate.  This  I  think  is  accomplished  in 
the  present  preparation,  here  exhibited. 
The  great  superiority  of  solid  fat  over  cod-liver  oil  consists  princi- 
pally in  the  fact  that  the  former  is  a  body  rich  in  stearin,  while  cod- 
liver  oil  is  chiefly  olein.  In  the  normal  diet  a  person  partakes  prin- 
cipally of  food  rich  in  the  former,  hence  it  is  that  a  similar  body  must 
be  presented  for  assimilation.  Cod-liver  oil  usually  assimilates  more 
rapidly  than  other  fats,  and  if  it  can  be  continued  in  any  case  for 
some  time,  rapid  improvement  generally  takes  place.  To  this  there 
as  the  objection  that  olein  cannot  replace  stearin  in  the  animal  sys- 
tem, and  the  work  is  not  thorough.  Again,  fats  containing  much 
olein  are  certainly  partially  assimilated  through  venous  absorption, 
and  this  is  a  reason  why  patients  so  soon  tire  of  the  oil.  The  portal 
■system  becomes  choked  up,  cathartics  are  necessary,  and  even  the 
igood  effect  produced  is  frequently  lost  by  the  course  rendered  neces- 
sary by  these  circumstances.  This  becomes  of  interest  to  pharma- 
cists, first,  from  it  being  to  our  interest,  in  a  pecuniary  way,  to  devise 
something  better  than  cod-liver  oil,  and,  second,  as  an  aid  to  the  phy- 
sician, pharmacy  should  select  such  agents  as  a  clear,  sound  theory 
suggests,  and,  by  scientific  manipulation,  so  combine  them  and  mould 
th em  that  they  may  he  of  the  most  potent  remedies  in  the  hand  of 
<her  sister  Medicine. 
Thus  pharmacy,  to  prevent  the  loss  of  fat  which  is  frequently  occa- 
sioned by  the  choking  up  of  the  portal  system  through  the  adminis- 
tration of  too  much  olein,  selects  a  solid  fat  which  is  only  absorbed 
by  the  lacteals,  and  thus  the  amount  of  fat  necessary  for  perfect  nu- 
trition can  be  administered  in  the  natural  manner.  The  fat  formed 
fey  the  assimilation  of  this  emulsion  is  of  a  firmness  not  readily  at- 
tainable by  the  administration  of  cod-liver  oil  or  other  similar  ele- 
ments of  nutrition.  The  administration  of  cod-liver  oil  in  connection 
with  the  emulsion  of  solid  fat,  however,  probably  answers  more  effi- 
ciently than  either  alone. 
The  emulsion  of  solid  fat  is  best  prepared  in  the  following  manner: 
Take  of  the  fresh  pancreas  of  the  pig,  one  hundred  pounds ;  lard, 
purified,  eighty  pounds;  water,  six  gallons. 
Dissect  off  all  the  fat  and  other  extraneous  matter  from  the  pan-
