PUBLICATIONS REVIEWED. 
Tomo I, No. 6, of Parergones del Instituto Geologico de Mexico 
contains a paper on Internal Hydrology of the district surrounding the 
City of Cadereyta Mendez, in the State of Queretaro. Senor Villarello 
gives a detailed account of tne geology and physical features, with espe- 
cial reference to the courses, qualities and availability of the underground 
water currents. His conclusions are not encouraging for the occurrence 
of extensive supplies of potable water under the area investigated. 
The Coal Number (March, 1905) of the Mining Magazine keeps up 
the record heretofore attained by this excellent periodical.
