2 DILRORIEL 
A PROPOSED INTERNATIONAL JOURNAL OF PETROLOGY.— The 
committee appointed by the Seventh International Congress of 
Geologists to consider plans for the establishment of an Inter- 
national Journal of Petrology has chosen Professor F’. Becke of 
Vienna, well known as the editor of Tschermak’s Mittheilungen, 
President of the Committee, and has taken the first steps toward 
the organization of such a journal. It has been proposed that 
articles appearing in it shall be printed in French, German, or 
English at the option of the author. 
While primarily intended for the publication of reviews and 
abstracts of all petrographical papers wherever published, it is 
suggested that it may include also articles which shall appear in it 
for the first time. The carrying out of this must depend upon 
the financial support the journal receives. 
The journal is to be managed by a committee appointed by 
the International Congress of Geologists, the committee to select 
an editor who shall have two assistants ; the editor and assistants 
to receive salaries for their services. 
The desirability of having one source, thoroughly up to date, 
to which to turn for information concerning all matters pub- 
lished on petrology is self-evident to all attempting to keep 
abreast with the rapid advance of this science. One has only 
to observe what a great impulse to the science of mineralogy 
has been given by the establishment of Groth’s Zeitschrift fir 
Krystallograplie, to be convinced of the usefulness and con- 
venience of such a journal. 
The necessity of forecasting as correctly as possible the 
financial support obtainable for such a journal has suggested to 
the American members of the committee the plan of calling 
attention to the enterprise and of inviting all interested in its 
success to communicate to either of them such suggestions or 
information as may aid in estimating the amount of annual
