76 J. H. MAIDEN, 
for twenty years’ continuous service, was in order that I 
might be present at that Congress. 
It was attended by very eminent men, and took the wise 
course of not attempting to ‘‘settle’’ certain difficult 
points, but, bearing in mind the great interest that had been 
aroused, of remitting important decisions to a second 
International Congress to be held in Vienna in 1905. It 
also enunciated the principle of holding an International 
Congress or Parliament of Botanists thereafter every five 
years, for the discussion of such matters of nomenclature 
as might be brought before it. There is therefore now in 
existence a duly constituted International Tribunal of 
nomenclature. I have already pointed out,’ that “‘the way 
is gradually being paved for the establishment of a ‘Tri- 
bunal of Nomenclature’ whose decisions no botanist may 
afford to disregard.”’ 
The next Congress is fixed for 1910 at Brussels. In 1903 
I published a presidential address” dealing with the great 
question of nomenclature, and ever since the Paris Congress 
I have been in touch with M. Emile Perrot the General 
Secretary of the Paris Congress, and Dr. John Briquet of 
Geneva, the ‘‘ Rapporteur Général’’ of the Vienna Congress, 
voting, asa member of the Paris Congress on certain points 
remitted for the consideration of members. 
Invitation was extended to members of the Paris Con- 
gress, and indeed to all botanists, to prepare resolutions 
and data for consideration of the Vienna Congress, whose 
members might therefore debate with the fullest knowledge. 
In consequence, a considerable number of valuable docu- 
ments were circulated amongst members including the 
following :—
