give  the  patient  a  teacupful  every  half  hour.  The  next  day  it  is  given 
every  two  hours,  and  then  4-6  times  a  day  until  the  cure  is  complete, 
which  generally  takes  from  2-3  weeks.  The  effects  are  in  the  follow- 
ing order  :  vomiting,  diarrhoea,  increased  urine,  strong  transpiration  ; 
then,  generally,  increased  appetite  and  craving  for  acidulous  beverages. 
The  diet :  easily  digested  food,  and  lemonade  or  other  acidulous  liquids. 
Koumiss — The  original  way  of  preparing  koumiss  (in  leather  bags)  is 
very  dirty  and  uninviting.  In  Russia  (Saratow)  the  following  method  is 
used,  according  to  Haurowiz  :  The  ferment  is  made  by  mixing  two 
teacupfuls  of  wheat-flour  dough,  two  spoonfuls  of  millet-flour,  one 
spoonful  of  honey,  one  of  good  beer  yeast  and  sufficient  milk  to  form 
a  not  too  thin  paste,  which  is  put  in  a  moderately-warm  place  to  fer- 
ment. This  ferment  is  now  put  in  a  linen  bag,  and  hung  in  a  jar  or 
keg  containing  sixteen  pounds  fresh  mare's  milk,  cover  and  let  stand 
till  the  milk  has  acquired  a  pleasant  acidulous  taste  (about  16-24  hours, 
according  to  the  temperature).  The  butter  and  cheese  particles,  which 
float  about,  are  now  skimmed,  the  liquid  is  poured  into  another  keg 
and  shaken  for  one  hour,  after  which  time  it  is  filled  into  bottles,  corked 
and  put  in  the  cellar  A  "  cure "  requires  twelve  to  fifteen  pounds 
of  milk  daily  (two  mares),  and  the  best  season  is  from  May  to  July. 
The  koumiss  is  taken  early  in  the  morning  every  half  or  one  hour  (a  tea- 
cup to  a  tumblerful  at  a  time)  and  plenty  of  exercise. 
The  Estimation  of  Phosphoric  Jcid^  by  means  of  a  volumetric  solution 
of  uranium,  is  rendered  quite  troublesome  by  titrating  the  latter.  It  is 
true,  that  we  are  told  only  to  dissolve  perfectly  dry  and  non-efHoresced 
phospate  of  sodium  lO'oSf  grm.  in  one  litre  distilled  water,  and  titrate 
with  this  solution  ;  but  the  trouble  is  to  get  always  phosphate  of  sodium 
possessing  the  above  qualities.  Dr.  C.  J.  Kayser (Sweden)  recommends, 
therefore,  the  following  :  Dissolve  pure  phosphate  of  sodium  in  distilled 
water  in  the  before-named  quantities.  Of  this  solution  take  50  c.c.  m., 
evaporate  in  a  tared  platinum  crucible  to  dryness,  and  heat  gradually  in 
a  sand-bath  until  the  salt  loses  no  longer  in  weight.  It  is  easy  now  to 
calculate  the  quantity  of  phosphoric  acid  contained  in  the  original  50 
c.c.  m.  of  the  solution,  and,  consequently,  the  titration  of  the  uranium 
solution  will  be  exact. — Farm.  Tidskr..^  1873,/).  130. 
Estimation  of  Nitrogen  in  Manures. — K.  Lund  recommends,  as  free 
from  errors,  to  mix  the  sample  of  manure  with  bitartrate  of  potassium 
and  soda-lime,  introduce  into  a  combustion-tube  and  ignite  as  usual.
