(2)  The  presence  in  the  mixture  of  an  excess  of  one  or  more  of  the  compo- 
nents increases  the  speed.  The  effect  of  an  excess  of  potassium  iodide  is 
about  the  same  as  an  equivalent  excess  of  potassium  chlorate.  But  a  corre- 
sponding excess  of  acid  causes  a  greater  increase  of  speed. 
(3)  Other  things  being  equal,  the  speed  of  the  reaction  is  modified  by  degree 
of  concentration  of  the  mixtures,  the  speed  increasing  with  the  concentration. 
(4)  To  obtain  the  complete  reduction  of  potassium  chlorate  by  potassium 
iodide  and  hydrochloric  acid  in  a  comparatively  short  time,  the  solutions  must 
be  concentrated,  there  must  be  quite  an  excess  of  both  potassium  iodide  and 
hydrochloric  acid,  and  the  mixture  must  be  strongly  heated. 
(5)  The  presence  of  an  excess  of  the  ordinary  inorganic  acids  accelerates  the 
reaction.  Assuming  their  respective  influences  as  indicating  their  relative 
strengths,  the  results  on  acceleration  show  the  following  order  of  strength  : 
(1)  hydrobromic  ;  (2)  hydrochloric  ;  (3)  nitric  ;  (4)  sulphuric. 
(6)  Organic  acids  and  boric  acid  do  not  increase  the  speed.

The  following  new  periodicals  relating  to  pharmacy  have  recently  appeared  : 
Annates  de  Pharmacie  is  a  monthly  journal  devoted  to  practical  pharmacy, 
pharmacognosy,  foods,  chemistry,  toxicology,  microscopy,  hygiene,  profes- 
sional interests  and  legislation.  The  editor  is  Fernand  Ranwez,  pharmacist  at 
Louvain,  Belgium,  and  the  publisher  is  Louis  Honart,  likewise  a  pharmacist,  at 
the  same  place.  The  first  number  starts  out  well  with  original  articles  on  the 
"Adulteration  of  Saffron,"  "  Syrups  of  the  Belgian  Pharmacopoeia"  and 
"  Pharmacy  in  Belgium  at  the  present  time."  There  are  also  reviews  from  other 
journals — varieties,  notes  and  bibliography.  The  two  succeeding  numbers 
which  have  reached  us  are  fully  equal  to  the  first. 
Medicine. — A  monthly  journal  of  medicine  and  surgery,  edited  by  Harold 
N.  Moyer,  M.D.,  and  published  by  George  S.  Davis,  Detroit,  Mich.  The 
first  number  consists  of  sixty-four  pages,  and  is  made  up  of  a  number  of 
original  papers  by  well-known  medical  writers,  and  of  a  comprehensive 
review  of  the  progress  of  medical  science  and  literature.
