spoonful  of  this  should  be  diluted  with  half  a  litre  of  water,  and 
this  quantity  taken  daily,  during  and  after  meals.  The  author 
attributes  the  favorable  results  of  this  treatment  to  the  continued 
action  of  the  medicaments  taken  internally. — Bull,  de  la  Soc.  de

Action  of  acetic  and  formic  acids  on  oil  of  turpentine. — Bouchardat 
and  Oliviero  report  that  by  the  action  of  glacial  acetic  acid  on 
laevogyre  oil  of  turpentine  in  the  cold  and  at  100°,  a  complex  mix- 
ture is  formed  of  laevogyre  terpilen,  terpilenol  acetate  (QoH^QH^), 
also  the  two  isomers,  borneol  acetate  and  isoborneol  acetate.  At  1 50- 
200°  the  formation  of  terpilenol  acetate  ceases.  The  presence  of 
water,  in  various  proportions,  retards  the  combination,  until,  when 
25  molecules  of  water  are  present,  the  action  ceases  entirely.  In 
the  other  case  a  partial  transformation  of  terebentene  into  active 
isomeric  terpilene  takes  place  as  is  proven  by  the  increase  of  rotatory 
power. 
The  action  of  formic  acid  differs  in  being  more  violent,  destroying 
the  rotatory  power.  In  the  presence  of  I,  3  and  5  molecules  of  water 
an  abundant  formation  of  free  terpin  takes  place.  By  this  action  of 
formic  acid  the  presence  of  small  quantities  of  terpin  is  explained 
in  hydrated  volatile  oils,  which  have  been  kept  for  a  certain  length 
of  time,  formic  acid  being  invariably  present  in  the  volatile  oils. —

Liquid  oxyphenol  (peroxydibenzol)  is  obtained  by  replacing,  in  a 
molecule  of  benzol,  2C6H6,  9  atoms  of  H  by  an  equivalent  of  the 
hydroxyl  group;  its  composition  is  C^H^Og.  Giuseppe  Reale 
ascribes  to  it  remarkable  physiological  action,  and  has  used  it  suc- 
cessfully in  diabetes  and  albuminuria.  Albumin  boiled  in  water  in 
the  presence  of  a  little  oxyphenol  loses  the  property  of  being  coag- 
ulated by  heat. — Riv.  Ital.  di  Terap.  e  Ig.}  through  Rev.  intern,  de

Formulas  for  eye-washes. — Emile  Berger  reports  to  the  Societ'e 
de  biologie,  that  by  associating  several  alkaloids,  he  has  obtained  a 
collyrium  which  is  more  active  and  less  toxic  than  when  a  single 
alkaloid  is  used.  Thus  a  mixture  of  atropine  sulphate  and  dubois- 
ine  sulphate,  of  each  0-3  gm. ;  cocaine  hydrochlorate,  2  gm. ;  and 
distilled  water,  100  gm.,  yields  a  mydriatic  at  least  as  powerful  as 
atropine  in  solution  1  to  100,  without  being  equally  toxic.  The
