GEOLOGICAL CORRELATION THROUGH VERTEBRATE PA¬ 
LEONTOLOGY BY INTERNATIONAL COOPERATION. 
Correlation Bulletin, No. 1. Plan and Scope. 
By Henry Fairfield Osborn, Chairman, and W. D. Matthew, Secretary, 
Section of Vertebrate Paleontology, International Correlation Committee, National 
Academy of Sciences. 
This is the first of a series of Correlation Bulletins which will be suc¬ 
cessively published in the Annals of the New York Academy of Sciences, 
as reports of special researches on geologic correlation through vertebrate 
paleontology. These researches have been instituted through a committee 
appointed by the National Academy of Sciences in 1908, with the special 
object of securing international cooperation in paleontology, similar to that 
which has proved so helpful in astronomy. The research is facilitated 
through a grant from the Baehe Fund of the National Academy of Sciences, 
founded in 1879. The Council of the New York Academy of Sciences has 
agreed to cooperate with this important work by the publication of the series 
of correlation bulletins. 
In this first bulletin it seems desirable to outline the history of organiza¬ 
tion and proposed method of procedure of the Committee. Correlation 
Bulletin No. 2, entitled “Fossil Vertebrates of Belgium,” contributed by 
Dr. Louis Dollo, of the Royal Belgium Museum of Natural History, will 
afford a practical illustration of the methods proposed. 
I Organization of Committee. 
At a meeting of the National Academy of Sciences, April 22, 1908, it 
was resolved: 
“That four members of the Academy be appointed by the President 
as a Committee on Paleontologic Correlation, including two specialists 
in Invertebrate and Vertebrate Paleontology, respectively. The com¬ 
mittee shall report at each meeting. The present committee shall serve
