8 Frazer on Int. Cong, of Geologists. 
Hunt was secretary. The committee announced to all scientific 
societies of the world the proposed inception of the plan during 
the French Exposition of 187S, and appealed to M. Tournouer, 
then the president of the Geological Society of France, for as- 
sistance. The Council of the society was made a committee of 
organization, in conjunction with the members of the Institute 
of France in the section devoted to matters akin to those about 
to engage the attention of the Congress, — including in these 
zoology and botany, and the professors of natural history chairs 
in Paris. [See vol. i, Proceedings of the International Congress, 
p. 27.] 
The first question submitted by the committee on organization 
for discussion by the Congress, was the unification of the no- 
menclature and the conventional symbols used in geology. The 
second was the boundaries between the terranes. The third re- 
lates to the works published on the ahgnment of dykes, and in 
part to experimental geology. The fourth (the respective value 
of faunas and floras in the determination of the boundaries of 
terranes) comprised the actual problems of paleontology." The 
fifth (the value of the mineralogical composition and of the tex- 
ture of rocks, from the point of view of their origin and their 
age) was suggested by the success of the application of the mi- 
croscope, and of the principles of optical science, to lithological 
questions. 
A provisional bureau was named by the Council of the Con- 
gress which issued a series of rules applicable to the Paris 
session.
