MEETINGS OF SOCIETIES. 
The meetings of the various societies that make the Museum their 
home will be resumed the first week in October. Papers on technical 
and general scientific subjects are read before these societies. The 
papers and discussions are often of popular character and are always 
of considerable general interest. The public is invited to attend the 
meetings, and Members of the Museum, on making request of the 
Director, will be provided with programmes of the meetings as they 
are published. 
The New York Academy of Sciences will begin its sessions for the 
season of 1905-1906 on Monday, October 9g, at 8.15 P.M., with a busi- 
ness meeting and meeting of the Section of Geology and Mineralogy. 
The programme will be as follows: 
PRroressor Rospert T. Hii, formerly of the United States Geo- 
logical Survey, will lecture on ‘‘The Republic of Mexico: Its Physical 
and Economic Aspects.’”’ Professor Hill has devoted more than 
twenty years to the study of Mexico, and his lecture embodies the 
results of extended, careful, and systematic research. The attention 
of the general public is particularly called to this meeting of the 
Academy, and those interested in our sister republic are cordially 
invited to attend. The lecture will be given in the Auditorium, and 
will be fully illustrated with stereopticon views.
