say, the system which includes the psammites of Condroz and 
the upper Old Red” [the words “the Lower Carboniferous 
(Kilborkan, Marwood, Pilton)” and “or the calciferous sand- 
stone Dura Den” were stricken out of the committee’s resolution 
at the request of Professor A. Geikie as not representing the real 
associations of these beds]. 
Carboniferous.—The question of associating the Permian with 
the Carboniferous provoked the most interesting discussion of the 
congress, Stur of Vienna, Lapparent, Blanford, and Professor New- 
berry spoke in favor ofsuch union. Hughes, Topley, Nikitin, anda 
great many others spoke against the association. Professor New- 
berry in the course of his remarks, said that “his honored col- 
league, Professor Hall, was of the opinion that the Permian did 
not exist in America, and that his own studies confirmed this 
view.” M. Neumayr thought “the decision of such questions 
as this should not depend upon a majority vote which would 
change in each country, and after each eloquent speaker (referring 
to M. Lapparent’s brilliant defense of the committee’s proposition). 
This view was finally taken, and the congress adopted, with about 
fiteen dissenting votes, the following proposition formulated by 
M. Dewalque: 
“The congress not wishing to pronounce an opinion on the 
scientific question will leave the classification as it is.” 
_ Triassic—After much debate the three-fold division of the 
Triassic was agreed to, but without giving names to the divisions. 
Jurassic—The division of this system into three was adopted, 
but without specifying the names of the divisions. 
It was agreed that each geologist might draw the upper hori- 
zon of the lias where he thought best. 
Cretaceous —It was agreed that the Gault should be joined to 
the Cretaceous. 
Tertiary.—-The divergence of views on this subject was so great 
that M. Capellini then in the chair, cut short the whole ques- 
tion by asking for a vote of confidence in the committee, which 
was unanimously given. 
Eruptives—Finally the seven-fold division of the eruptive rocks, 
in as many tints of red, was carried without opposition. 
This completed the serious geological work of the congress, 
and it was then agreed to meet in London in 1888. A committee 
consisting of Hughes, Geikie, Blanford and Topley was appointed 
to make the necessary arrangements, and the congress adjourned. 
During the course of the congress addresses were given by M. 
Gaudry on certain reptiles; Newberry, on a new large Devonian 
fish from America; Posepuy, on the fluid condition of the earth’s 
interior; Ochsenius (in German), on the origin of salt deposits; 
Neumayr, on the plan for the “ nomenclator palzontologicus,” 
which he is compiling (and which the congress voted to publish 
under its auspices and through the agency of a special committee 
consisting of MM. Gaudry, Zittel, and Neumayr); M. Nikitin
