84  NUTRITIVE  VALUE  OF  "  EXTRACT UM  CARNIS." 
supply  of  fresh  meat  is  insufficient,  and  this  will  get  worse  as 
the  population  increases.    For  an  army,  for  example,  it  will  not 
be  difficult  to  provide  and  store  up  the  necessary  amount  of 
grain  or  flour.    Sugar,  too,  as  well  as  fatty  substances  and  the 
like,  will  be  procurable,  their  transport  and  preservation  offer- 
ing scarcely  any  difficulty.    But  there  may  easily  occur  a  defi- 
ciency of  fresh  meat.    Salted  meat  but  inadequately  replaces 
fresh  meat,  because,  in  the  process  of  salting,  a  large  quantity 
of  the  extractive  principles  of  the  meat  are  lost ;  besides,  it  is 
well  known  that  those  who  live  on  salt  meat  for  a  continuance 
become  subject  to  different  diseases.    Dried  meat  generally 
means  tainted  meat  scarcely  eatable.    Extractum  Carnis,  com- 
bined with  vegetable  albumen,  enable  us  to  make  up  the  defi- 
ciency, and  that  combination  is  the  only  one  at  our  disposal. 
What  was  said  of  an  army  also  holds  good  of  those  European 
nations  in  general  that  do  not  produce  a  sufficiency  of  meat.  By 
making  the  most  of  the  herds  of  South  America  and  Australia, 
in  using  them  for  the  preparation  of  Extractum  Carnis,  and  by 
the  importation  of  corn  from  the  West  of  United  States  and 
other  corn-growing  countries,  the  deficiency  may  be  made  up, 
although  not  to  the  full  extent.    For,  supposing  ten  manufac- 
tories, producing  together  ten  millions  of  pounds  of  extract  of 
meat  from  a  million  oxen  or  ten  millions  of  sheep,  that  whole 
quantity  would  provide  the  population  of  Great  Britain  only 
with  one  pound  yearly  for  every  three  persons — that  is,  one 
pound  a  day  for  every  1100  persons. 
I  have  before  stated,  that,  in  preparing  the  extract  of  meat, 
the  albuminous  principles  remain  in  the  residue ;  they  are  lost 
for  the  nutrition,  and  this  certainly  is  a  great  disadvantage.  It 
may,  however,  be  foreseen  that  industrial  ingenuity  will  take 
hold  of  this  problem  and  solve  it,  perhaps  by  a  circuitous  road. 
For  if  this  residue,  together  with  the  bones  of  the  slaughtered 
beasts,  be  applied  to  our  fields  as  manure,  the  farmer  will  be 
enabled  to  produce  a  corresponding  quantity  of  albuminous 
principles,  and  to  better  supply  our  towns  with  them,  either  in 
the  shape  of  corn  or  of  meat  and  milk.  Made  into  a  market- 
able state,  it  may  hereafter  replace  the  Peruvian  guano,  which 
very  soon  will  disappear  from  the  market.
