of  potassium  hydrate  (from  alcohol)  20  gm.  in  TOO  cc.  alcohol  of  90 
per  cent,  which  has  been  volumetrically  tested  (-1  cc.  =  -0047  K20). 
(3)  A  solution  of  phenolphthalein  I  eg.  in  500  cc.  alcohol  of  90 
per  cent,  to  which  is  added  sufficient  potassium  hydrate  to  produce 
a  slight  rose  color.  The  method  of  using  is  as  follows  :  To  10  grams 
vaselin  in  a  porcelain  capsule  are  added  10  cc.  of  solution  No.  2. 
The  mixture  is  heated  on  a  water-bath  under  constant  stirring  for  eight 
minutes  ;  then  50  cc.  of  No.  3  are  added  and  heated  close  to  the  point 
of  boiling.  The  titrated  sulphuric  acid  is  then  added,  drop  by  drop, 
until  the  mixture  becomes  colorless.  The  number  of  cc.  of  sulphuric 
acid  used  is  subtracted  from  the  number  of  cc.  necessary  to  neu- 
tralize 10  cc.  of  the  potassium  hydrate  solution  and  the  difference 
multiplied  by  -0047  which  gives  the  amount  of  K20  used.  The 
further  calculation  is  by  using  the  equation  n  :  x  ::  1-635  :  I0>  where 
n  represents  the  quantity  of  potash  absorbed.  The  result  is  then 
multiplied  by  10  which  gives  the  percentage  of  impurities  present. 
The  number  1-635  (grams)  represents  the, amount  of  K20  necessary 
for  decomposing  10  grams  of  the  fats. 
Analysis  of  Woman's  Milk. — H.  Wartha  {Ann.  diChim.  e  di  Far- 
macol.  xiii,  1891,  179)  analyzed  the  milk  of  25  women,  ranging  in 
age  from  18  to  40  years,  with  the  following  results  :

Pillcoating  with  Salol. — Dr.  Ceppi  recommends  that  pills,  which 
should  be  disintegrated  in  the  intestines,  be  coated  with  salol,  as 
this  is  dissolved  by  the  alkali  which  is  always  present  there.  Yvon 
{Progres  medical,  Aug.  15,  1 891),  publishes  the  following  formula 
for  this  coating  :  Salol,  2  gm.,  tannin,  5  dgm.,  ether  of  500,  10 
gm.  This  is  applied  in  the  same  manner  as  the  coating  with 
balsam  of  tolu. 
Antisepsis  of  the  Intestinal  Canal. — Dujardin-Beaumetz  {JSI ouveaux 
Remedes,  189 1,  497),  uses  the  following  for  this  purpose:  Salol,  bis- 
muth salicylate,  sodium  bicarbonate  of  each,  10  gm.,  to  be  divided 
into  30  cachets,  and  one  to  be  taken  before  breakfast  and  dinner.
