IMPORTANCE  OF  SUGAR  AS  A  FOOD. 
Chauveau  recently  demonstrated  before  the  Paris  Academie 
des  Sciences  that  the  general  assumption  in  regard  to  the  amount  of 
calories  produced  by  sugar  is  erroneous.  Instead  of  the  theoretic 
assertion  that  3  grammes  of  sugar  are  equivalent  to  the  nine 
calories  produced  by  the  consumption  of  1  gramme  of  fat,  only 
0  756  gramme  of  sugar  is  required  to  produce  this  same  amount 
of  calories.  He  urged  the  repeal  of  duties  which  tend  to  restrict  the 
use  of  sugar,  contending  that  the  people  should  be  urged  to  use  it 
more  freely. — Jour.  Amer.  Med.  Assoc.,  May  21,  1 
THE  ANTI-EMETIC  PROPERTIES  OF  ICELAND  MOSS. 
Deguy  and  Bricemarct  [Journal  des  Practiencs,  annali  di  farma- 
coterapia  e  chimica,  April),  in  making  use  of  a  tincture  of  this  drug 
on  account  of  its  nutrient,  demulcent  and  bitter  tonic  properties  in 
cases  of  gastric  disturbance,  find  that  it  possesses  marked  anti- 
emetic properties.  From  30  to  50  drops  are  administered  in  a  little 
seltzer  water.  The  drug  does  not  seem  to  have  any  effect  on  hys- 
terical vomiting,  and  the  authors  have  not  as  yet  had  occasion  to 
use  it  in  the  vomiting  of  pregnancy. —  Vide  New  York  Med.  Jour.,

COMPULSORY  VACCINATION. 
While  England  [Revue  Medicaley  Quebec,  May  4)  is  still  disput- 
ing over  Jenners'  discovery,  Japan  has  made  not  only  primary  vac- 
cination but  quinquennial  vaccination  compulsory,  and  ordains  the 
exclusive  use  of  aseptically  prepared  calf  lymph. 
HYDRASTIS  CANADENSIS. 
In  the  Independance  Medicale  for  April  17th,  M.  Marini,  of  Bag- 
dad, relates  his  experience  with  this  drug  in  the  treatment  of 
haemorrhage  in  case  of  haemorrhoids,  tuberculosis  and  dysentery, 
and  states  that  he  has  obtained  remarkable  results.  He  also  main- 
tains that  it  is  the  preferable  remedy  in  the  haemorrhages  of  fibro- 
myoas,  and  that  it  is  the  best  means  of  combating  the  haemorrhages 
of  pregnancy  at  any  stage,  provided  that  it  is  taken  at  sufficiently 
prolonged  intervals ;  that  is,  20  drops  of  the  fluid  extract  every
