volumes for the vigor, liberality and alertness of Italian science. 
The Third Session, or Berlin Congress. 
The subsequent history of the Congress down to the end of 
the Berlin meeting has been given to the public both through 
the pamphlet of the w^riter on " The work of the International 
Congress of Geologists and its committees," published by the 
American committee, and in numerous communications to the 
scientific press. 
A brief r^sum^ of these will here be given for the better en- 
lightenment of those who have formed their opinions of the Con- 
gress from vice president Gilbert's address before Section E at 
the last meeting of the A. A. A. S. in New York. 
M. Renevier on behalf of the international committee on the 
geological map of Europe, reported that it had assembled in 
1S82 at Foix, and in 1883 at Zurich. He announced the ar- 
rangements made with the firm of D. Reimer and Co., of 
Berlin, for the publication of the map, and that Prof. Kiepert 
would provide a base which should include all new data both 
published and unpublished. 
Each of the great European States (viz: France, Spain, Italy, 
Austro-Hungary, Russia, Scandinavia, Germany, and Great 
Britain,) had agreed to take 100 copies of the map, when com- 
pleted, at a cost of 100 francs each.^ 
' The secretary of the American committee was authorized to state to 
the international committee on the map that the United States would 
take 100 copies under the same conditions as the above named countries. 
Inasmuch as the United States government cannot be counted upon to 
subscribe by an appropration of money, he was orderd to send out circu- 
lars and to procure subscriptions of institutions and individuals. This he 
has done, no less than three circulars having been addressed by him dur- 
ing the last two years to the persons mentioned in the catalogue of the 
members of Section E, A. A. A. S., in his own and the scientific ex- 
change list of the United States geological survey., and to the individuals 
and institutions mentioned in Cassino's Scientist s Directory . Besides this, 
every institution of learning recorded in the report of the "Educational 
Bureau" was addressed. Yet notwithstanding these expensive and 
laborious efforts to reach all classes of the American public likely to be 
interested in either the best map of Europe, or the science of geology 
but 75 copies of the 100 have been subscribed for. It is true that all the
