International Geological Congress. — Frazer. 209 
in the case at Berlin). (2) The business of the Congress might suffer 
from the distractions incident to a world's fair. If the American com- 
mittee, however, desires the postponement these gentlemen will take 
the necessary steps to secure the formal sanction of the Congress. 
The American committee should obtain the oj)inions of Beyrich, 
Capellini, Dewalque, Hauchecorne, and Kenevier. 
Prof. T. McKenny Hughes. Personally I have no objections to the 
postponement to '92 if it recommends itself to your committee, but 
before answering categorically I wish time to consult other members 
of the last session. 
G. Deiualque. While the exposition will bring more geologists to 
the Congress its distractions will turn their attention from its work. 
Besides a decision of the Congress should not be changed without 
grave reason. But the committee on organization is best able to decide 
this question and we shall abide by its decision. 
E. Beyrich. The postponement of the Congress will be desirable if 
it secure a session during the continuance of the world's fair. 
G. Capellini. The idea of making the date of the Congress and 
Exposition coincide has been found excellent b}'^ all my colleagues 
whom I have been able to consult. I was asked in France by many 
geologists to urge this postponement. It appears that the Englishmen 
are not of this opinion but it is to be hoped that after the vote of the 
majority they will agree to the postponement to 1892. You may 
regard my vote for it as that of all the Italian geologists interested in 
the Congress. 
E. Renevier. I have absolutely no objection to the postponement of 
the Congress to 1892. 
C. LeNeve Foster. It will be well to adjourn the session from 1891 
to 1892 in view of the probability of the international exhibition in 
America during the latter year. 
C. Barrois. Personally I prefer '92 to '91, but the Americans should 
decide. 
K. Martin. The postponement of the Congress on the ground pro- 
posed seems desirable. 
/. F. N. Delgado. I adopt on the question of the postponement 
entirely tlie views of the signers of the letter of inquiry. 
A- de Lapparent. My personal opinion is that there is every advan- 
tage in causing the date of meeting of the Congress to coincide with 
that of the proposed exposition by the United States. 
Dr. Zittel. I would leave the decision entirely to the American 
organization committee and will agree with any conclusion to which 
it may come whether to hold the meeting in 1891 or 1892. 
/. Vilanova. I give my complete assent to the happy thought of 
convening the Congress in 1892 and promise my attendance. 
A. InoKtransef. I find the idea very felicitous of adjourning the 
Congress to 1892, and send you my consent. 
M. Neuniayr. Before answering your circular I addressed a note to 
some of the most authoritative of our geologists. The unanimous 
opinion (which I share) is that there is no ol)jection to such post- 
ponement if our American colleagues think it useful to the objects of 
the Congress. 
J. Szabo. I think the proposition sufficiently called for, and I have 
the honor of declaring my support of it. 
F. Giordarw. It is my opinion and that of several of my colleagues 
from here that it is advisable to postpone the Congress from 1891 to 
1892 which is to meet at Philadelphia. 
T. H. Huxley. My answer to your letter of the 22nd of November 
has been unfortunately delayed in consequence of my absence from 
home. As you may be aware ill health prevented me from being
