carbolic  acid  cannot  be  detected  by  the  usual  tests  in  this  mixture,  the 
formation  of  a  chemical  compound  seems  to  be  indicated.  It  has  a 
strong,  aromatic  odor  and  an  acrid,  burning  taste,  dissolves  readily  in 
alcohol,  ether,  chloroform  and  a  mixture  of  equal  parts  of  alcohol  and 
glycerin,  also  in  alkalies,  but  is  sparingly  soluble  in  water.  Urine  to 
which  a  small  quantity  of  eulyptol  has  been  added,  remains  un- 
changed for  fully  a  month. 
Hypodermic  injection  of  cocaine  and  mercury,  useful  in  syphil- 
itic disorders,  is  recommended  by  Dr.  Mandelbaum  (Monatsh.  f.  pr. 
Dermat.)  to  be  prepared  as  follows : 
Cocaine  hydrochlorate  0-050  gm.  (gr.  f). 
Mercuric  cyanide  0  001       (gr.  j). 
Distilled  water  15  drops. 
Administration  of  Paraldehyde. — Dr.  R.  G.  Eccles  recommends  the

Thymol  as  a  twnicide  and  tcenifuge,  is  recommended  by  Dr.  Numa 
Campi,  its  action  being  simple  and  rapid,  and  unaccompanied  by  any 
disturbance,  except  a  depressing  effect,  easily  counteracted.  In  the 
evening  he  ordered  20  gm.  (5v)  of  castor  oil  to  be  taken  fasting ;  in 
the  morning  he  prescribed  8  gm.  (5ii)  of  thymol,  divided  into  twelve 
doses,  one  to  be  taken  every  quarter  of  an  hour ;  twenty  minutes 
after  the  last  dose  had  been  swallowed,  another  20  gm.  (5v)  of  castor 
oil  were  taken.  A  few  minutes  after  a  tcenia  medio-canellata  three 
and  a  half  meters  in  length  was  evacuated,  the  head  being  dead.  The 
depressing  effects  were  promptly  counteracted  by  the  use  of  stimulants, 
cognac  and  rum  being  suitable  for  the  purpose. — Buffalo  Med.
