September last contains an abstract of a paper by W. Dames on 
the Archeopteryx discovered in 1877 in the lithographic stone at 
Blumenberg in Bavaria (the same rock that afforded the speci- 
men described by Professor Owen), which is illustrated by a plate 
showing the head with the tooth-bearing jaws, from which the 
accompanying figure of the head is taken, reduced in size. The

4. The deposition of Ores; by J. S. Newserry, (School of 
Mines Quarterly for May, 1884, New York).—Dr. Newberry’s 
extensive knowledge of the ore deposits of western North America 
any essential change; that many veins have no connection with 
igneous rock; 
no associated ore deposits; and favors the view of Richthofen that 
the filling of many of the veins was the result of “ the leaching of 
deep-seated rocks, perhaps the same that enclose the vein above, 
by highly heated solutions, which deposited their load near the 
surface.” The region, he observes, is conspicuous for the number 
of its hot springs, and it is evident that these are the last of the
