day.  Injections  are  made  by  adding  from  I  drachm  to  I  ounce 
to  a  pound  of  water.  In  wounds,  cataplasms  may  be  made  from  the 
powder  of  the  plant,  or  a  concentrated  solution  of  the  extract  may 
be  applied  by  means  of  lint. 
We  copy  from  the  proceedings  of  the  Academia  de  Medicina  de 
Mexico,  session  of  February  21,  1866:  "Dr.  Lucia  has  repeatedly 
used  Commelina  to  cure  metrorrhagia,  and  always  with  success.  Dr. 
Yillagran  has  also  used  the  extract  in  injections,  the  dose  being  a 
drachm  to  a  pound  of  water,  to  cure  metrorrhagia,  and  has  always 
obtained  the  most  satisfactory  results.  He  has  lately  used  it  in  an 
instance  of  cancer  in  the  stomach,  and  has  attained  most  unexpected 
success.  Dr.  L.  Jimenez  has  also  been  fortunate  in  the  use  of  injec- 
tions of  extract  in  two  cases  of  uterine  cancer,  and  in  leucorrhcea 
accompanied  with  chlorosis.  Dr.  Miguel  Jimenez  has  used  the  ex- 
tract since  the  year  1864,  and  has  made  many  experiments  with  the 
plant  which  prove  its  activity  as  a  hemostatic.  The  greatest  results 
are  obtained  according  to  this  physician  by  the  dose  of  a  drachm  in 
a  pound  of  water.  Its  utility  is  incontestable  in  uterine  cancer,  but 
it  is  also  useful  in  other  forms  of  hemorrhage.  Dr.  M.  Jimenez 
remembers  an  instance  of  hemoptysis  in  which  he  was  surprised  by 
the  good  results  obtained  with  this  medicine,  for  it  prolonged  the 
life  of  the  patient  in  an  unexpected  manner.  He  has  also  used  it  to 
cure  hemorrhoidal  flux  with  success.  He  has  failed,  however,  in 
some  other  cases  of  hemoptysis,  on  account,  perhaps,  of  the  patient 
vomiting,  which  prevented  the  action  of  the  remedy." 
I    RIEGLER'S  METHOD  FOR  ESTIMATING  SUGAR  IN 
URINE. 
By  Henry  C.  C.  Maisch,  Ph.G.,  Ph.D. 
This  method,  as  described  on  p.  228  of  the  American  Druggist, 
estimates  the  amount  of  sugar  contained  in  urine  indirectly  by  means 
of  Fehling's  solution.  The  reaction  on  which  this  depends  is  the 
liberation  of  nitrogen  when  Fehling's  solution  is  brought  in  contact 
with  phenylhydrazine  hydrochloride. 
The  manner  of  applying  this  test  is  to  boil  the  urine  and  Fehling's 
solution,  and,  after  connecting  the  apparatus,  the  phenylhydrazine 
solution  is  added.    In  other  words,  the  balance  of  the  Fehling's
