On  Wednesday  a  meeting  of  the  Association  Internationale  des 
Botanistes  was  held,  at  which  reports  of  the  treasurer  and  secretary 
were  presented.  The  most  important  action  taken,  by  an  over-

next  meeting  will  be  held  in  Montpellier  in  1908.  The  new  officers 
are  :  Wettstein,  president;  Flahault,  vice-president;  the  present  sec- 
retary and  treasurer  were  re-elected.
