l3gical  discharges,  in  proportion  to  the  albuminoids  they  con-
tain. Of  these  spermatorrhoea,  leucorrhoea,  gleet,  albuminuria,
chyluria,  and  chronic  dysentery  may  be  mentioned.  Malig-
nant growths,  again,  produce  anaemia  by  the  constant  drain
they  maintain  on  the  nutrient  resources  of  the  blood.  Symp-
tomatic anaemia  may  also  be  the  result  of  certain  poisons
previously  referred  to,  of  animal  parasites,  of  spleen  disease,
of  scurvy,  and  of  venereal.  It  may  also  arise  from  haemor-
rhages external  or  internal.  Haemorrhoids,  for  instance,  are
a  frequent  source  of  anaemia.  After  profuse  bleeding  the
blood  is  not  only  diminished  in  quantity,  but  is  relatively
poorer  in  albuminoids  and  red  corpuscles,  and  richer  in
water.  This  is  probably  explainable  by  the  diminution  of
llood-pressure  which  the  bleeding  produces,  and  by  the  con-
sequent dilution  of  the  blood  from  the  tissue  juices  by  watery
osmotic  current.
