A  NEW    REAGENT    FOR    ALBUMIN    IN    URINE.  M.    and    Ad.  Jolles 
(Union  phar  mac.  ;  Nouv.  Remed.,  1891,  No.  7),  propose  the  following 
method  for  testing  for  albumin  :  8-10  cc.  urine  are  mixed  with  an 
equal  volume  of  concentrated  hydrochloric  acid  and  to  this  mixture 
are  added  from  a  pipette  a  few  drops  of  a  saturated  solution  of  chlo- 
ride of  calcium  in  such  a  manner  that  the  liquids  will  not  mix.  In 
presence  of  even  traces  of  albumin  the  dividing  line  will  show  a 
distinct  white  cloudiness. 
Derivatives  of  Salol  in  urine.- — Lacroix  (Repertoire  de  Phar- 
macie  ;  Bull,  de  Therapeut.,  1891,  cxx,  284)  calls  attention  to  the 
fact  that  patients  taking  salol  internally  or  using  it  externally  pass 
a  urine  having  the  property  of  reducing  certain  metallic  oxides 
(copper,  silver  and  bismuth)  just  as  is  the  case  with  diabetic  urine. 
The  examination  with  the  saccharometer  can  also  not  be  depended 
on,  the  rotatory  power  of  these  salol  compounds  being  opposed  to 
that  of  glucose.  The  author  gives  an  optical  and  a  chemical 
method  for  distinguishing  between  the  two.  After  treating  the 
urine  with  subacetate  of  lead,  a  test  tube  holding  15  cc.  is  half 
filled  with  the  same;  to  this  is  added  -05  gm.  phenylhydrazin 
hydrochloride  and  -2  gm.  pure  acetate  of  sodium.  The  test  tube  is 
then  heated  to  ioo°  C.  (21 2°  F.)  on  a  water-bath  for  half  an  hour. 
The  contents  are  then  poured  into  some  water  and  allowed  to  cool. 
The  precipitate  formed  is  examined  with  the  microscope.  Glucose 
gives  a  crystalline  precipitate  while  the  salol  compound  gives  an 
amorphous  one.  The  other  method  is  as  follows :  100  cc.  urine 
are  shaken  with  I  gm.  sulphuric  acid  and  about  50  cc.  pure  ether; 
it  is  then  permitted  to  separate.  The  upper  layer,  containing  the 
derivatives  of  salol,  is  evaporated,  the  residue  dissolved  in  water  and 
a  few  drops  of  perchloride  of  iron  are  added  to  it.  This  would  give 
rise  to  a  violet  color  in  case  salol  were  present.  The  lower  layer, 
after  separation  from  the  ethereal  solution,  is  treated  with  subacetate 
of  lead,  filtered,  and  the  glucose  then  estimated  in  the  usual 
manner. 
IodoL — Dr.  Trouchet,  of  Larochelle  (Nouv.  Remed.,  1891,  p.  298), 
publishes  the  following  formulae  for  the  exhibition  of  iodol  (1)  in 
the  form  of  an  emulsion  :   iodol  I  gm.,  glycerin  10  gm.,  water  20
