iferous stalagmite which has yielded several thousand bones and fragments, 
of which between 4,000 and 5,000 are determinable specimens.  Fifty- 
two species have been determined, including twenty-one extinct species. 
The fauna is certainly as old as the middle Quaternary. Associated with 
these fossils are some pointed and polished bones, fragments, and others 
with peculiar perforations that seem hard to explain except by human 
origin. The phenomena of the other caves are similar, though more 
recent. In one of them were parts of a human skeleton incrusted with 
stalagmite. But Dr. Merriam is very conservative, and casts doubt both 
on the human origin of the perforated and polished bones, and on the 
great antiquity of the human skeleton. €.. WW. 
Geology oj the Volcanic Arca of the East Moreton and Wide Bay Dis- 
tricts, Queensland. By H. I. Jenson. (Proceedings of the 
Linnean Society of New South Wales, April, 1906, Part I, pp. 
73-173, Plates V—-XVI.) 
The physiography, general geology, and petrology are discussed. There 
are pre-Devonian schist, and gneiss, probably Archean. The Paleozoic, 
including the Gympic series (Carboniferous ?), is highly metamorphosed. 
The only other sedimentary rocks are faulted, Jura Trias feldspathic 
sandstones, with tuff and coal. The igneous rocks include tonalite, granite, 
aplite, epidiorite, granophyre, quartz-diorite, porphyrite, monzonite, s6lus- 
fergite, rhyolite, trachyte, comendite, and pantellerite. These are described 
petrographically, with chemical analyses, and calculations of their posi- 
tions in the quantitative system. C. W. W. 
Copper Deposits of the Clijton-Morenci District, Arizona. By WALD- 
MAR LINDGREN. (U. S. Geological Survey, Professional Paper 
No. 43.) Pp. 375, 24 plates. Washington, D. C., 1905. 
The three principal mines of this district produced 53,400,000 pounds 
of copper in 1903. The ores are associated with post-Cretaceous intru- 
sions of acid porphyries, and are thought to have derived their metals 
directly from the solutions accompanying these intrusions. Most of the 
ore is in the form of local replacement and impregnation of the country 
rock through contact metamorphism; circulating atmospheric waters were 
not concerned in their origin. But there are also some fissure veins of the
