combines  with  acids  to  form  basic  and  neutral  salts.  Benzoylcin- 
chonine  is  feebly  laevogyre  and  the  rotary  power  of  its  acid  solutions 
is  inferior  to  that  possessed  by  the  alcoholic  solutions,  and  diminishes 
as  the  quantity  of  acid  is  increased. 
The  author  has  likewise  prepared  and  studied  a  number  of  salts 
of  this  base. — Jour,  de Pharm.  et  de  Chim.,  November,  1893,  p.  405. 
Guaiacol,  used  as  a  protective,  has  been  studied  in  its  effects 
by  L.  Guinard,  who  concludes  that  the  lowering  of  the  temperature 
which  has  been  noticed  upon  using  guaiacol  for  this  purpose  is  not 
due  to  the  absorption  of  the  medicament  by  the  skin ;  the  rapidity 
of  the  action  being  sufficient  proof,  although  it  is  possible  after  a 
time  through  its  local  action  upon  the  epidermis.  The  presence  of 
guaiacol  in  the  urine  of  patients,  upon  whom  it  has  been  used  as  a 
protective  is  due  to  its  vapors  penetrating  the  respiratory  passages, 
although  this  quantity  is  not  sufficient  for  producing  the  lowering 
of  temperature.  In  noting  the  local  and  general  effects  of  guaiacol 
it  is  necessary  to  take  into  consideration:  (1)  The  quality  of  the 
product;  (2)  the  susceptibility  of  the  individual,  and  (3),  his  state  of 
health  ;  there  is  little  effect  upon  the  temperature  of  apyretic  subjects. 
The  local  effect  of  guaiacol  is  more  pronounced  if  the  part  pro- 
tected is  excluded  from  the  air  by  an  impermeable  covering. — Bull.

Sulphur  ointment,  associated  with  oil  of  cade  and  green  soap,  is 
used  by  Hebra,  in  the  treatment  of  prurigo,  and  the  following  has 
been  formulated  by  him  :  sulphur,  15  gm.;  oil  of  cade,  15  gm.;  green 
soap,  30  gm.;  lard,  30  gm.,  and  prepared  chalk,  10  gm. — Rev.  de

Reagent  for  detecting  albumin  in  icrine. — The  reagent  (Spiegler's) 
consists  of  the  following  :  Bichloride  of  mercury,  2  p.;  tartaric 
acid,  1  p.;  distilled  water,  50  p.;  glycerin,  5  p.  The  urine  is 
strongly  acidulated  with  acetic  acid,  filtered,  and  by  means  of  a 
pipette  the  filtered  liquid  is  introduced  into  a  test-tube  containing 
2  cc.  of  the  reagent.  If  albumin  is  present  a  white  ring  will  appear 
at  the  point  of  contact.  The  reagent  will  detect  1  1350,000. — Boll.
