providing  the  fat  is  present  in  not  too  large  quantity,  as  the  calcium 
soap  in  any  quantity  lumps  together  and  prevents  washing  ;  for  this 
purpose  the  first  filtrate  and  washings  are  concentrated  to  100  cc, 
neutralized,  precipitated  with  calcium  chloride,  the  precipitate 
collected  upon  a  weighed  filter  (dried  at  100°  C),  washed  with  as 
little  water  as  possible  to  remove  the  chlorides,  dried  at  uo°  C.  and 
weighed  ;  by  ignition,  the  weight  of  CaO  is  found,  which  subtracted 
from  the  weight  of  the  precipitate,  gives  the  weight  of  the  fatty  acid 
anhydrides.  To  calculate  the  weight  of  the  fat,  the  glycerin  anhydride 
corresponding  to  calcium  oxide  must  first  be  ascertained,  which  is 
done  by  multiplying  the  weight  of  the  CaO  by  0774 ;  then  adding 
this  and  the  weight  of  the  fatty  acid  anhydrides,  there  results  the 
weight  of  the  fat  in  the  quantity  taken  for  analysis. — Dr.  J.  Klimont,

Sucrol,  the  trade  name  finally  adopted  for  /-phenetol-carbamide 
was  noted  in  the  Am.  Jour.  Pharm.,  1892,  611  ;  it  is  best  adapted 
for  its  uses  in  a  fine  crystalline  form.  It  melts  at  1600,  is  soluble  in 
alcohol,  ether,  hot  hydrochloric  and  acetic  acids;  100  cc.  water  at 
20°  dissolve  0-16  gm.,  at  8o°  0  65  gm.;  it  has  about  200  times  the 
sweetening  power  of  sugar.  There  is  some  difficulty  in  moistening 
the  powdered  sucrol,  but  this  is  overcome  by  using  it  in  minute 
crystals  ;  used  for  sweetening  liquids,  like  tea,  coffee,  etc.,  the  hot 
liquids  should  be  poured  on  the  sucrol  previously  placed  in  the  cup. 
In  pharmaceutical  use  as  a  sweetener,  sucrol  has  not  the  power  of 
overcoming  the  intensely  bitter  taste  of  drugs  ;  a  solution  contain- 
ing quinine  sulphate  10,  sulphuric  acid  six  drops,  distilled  water 
100  0  and  sucrol  o- 1  tastes  intensely  bitter,  acid  and  sweet  at  the 
same  time  ;  in  a  powder  containing  morphine  hydrochlorate  0  05, 
starch  2-50,  and  sucrol  0-05  the  bitter  taste  is  disguised  better  than 
is  possible  with  sugar  ;  in  substituting  sucrol  for  sugar  as  in  the 
above  formula  some  inert  powder  must  be  introduced  to  make  up 
the  quantity.  Physiological  experiments  by  Dr.  Paschkis  proclaim 
sucrol  a  harmless  substance,  it  not  interfering  with  digestion,  respU 
ration  or  circulation  ;  administered  for  some  time  the  urine  remains 
normal,  traces  of  sucrol  are  only  to  be  found  in  it  after  taking  large 
doses  (0-5  or  more).  As  a  test  for  sucrol,  Dr.  Berlinerblau  boils  for  a 
a  short  time  a  small  quantity  in  a  test  tube  with  2-3  drops  each  of 
carbolic  and  sulphuric  acids ;  after  cooling  the  syrupy,  red  liquid  is 
poured  into  half  a  test-tubeful  of  water,  thoroughly  mixed  and
