248 The American Geologist. October looi. 
The scope of his studies, and of his writings, was broad. 
As a scientist he belonged to the old school, to which belonged 
most of the geologists of fifty years ago. He did not content 
himself with specialization in any line, but participated in 
physics, paleontology, glacial geology, prehistoric anthropol- 
ogy, and in all general geology, biology and botany. 
He was educated at the University of London from which 
he received the degrees of B. A. aixl D. S. He was professor 
of Natural Science at Antioch College, Ohio, 1873 to 1881 ; 
paleontologist to the Second Geological Survey of Pennsyl- 
vania, professor of Natural Science at Buchtel college, Akron, 
Ohio, from 1883 to the time of his removal to Pasadena 
(1898) where he was professor of biology and geology in the 
Throop Polytechnic Institute till the time of his death He 
was a fellow of the Geological Societies of London, Edin- 
burgh and America, and of the American Association for the 
Advancement of Science. He was greatly beloved and re- 
vered by his pupils and by all others with whom he came into 
contact. In the highest sense he was one of humanity's natural 
noblemen. n. h. w. 
THE ORIGIN OF AUSTR.\LIAN IRON ORES. 
A recent publication by the Department of Mines and Agri- 
culture of New South Wales'*' contains a valuable contribution 
to the origin of iron ores. Recognizing various conditions and 
origins of iron ore, as given by the author, the writer refers here 
specially to the aluminous iron ores and bauxites of Wingello. 
It is important that like some others Mr. Jacquet associates 
bauxite and hematite in a common discussion and assigns to 
them an identical origin, viz. a change from igneous rock, gen- 
erally basalt. No such associated origin has been ascribed to 
the bauxite deposits of the United States. The intimate con- 
nection of the pisolitic iron ore with basalt in New South 
Wales appears to have been noted by C. S. Wilkinson in 1872, 
and later by Mr. T. W. E. David. Mr. David says : "This form- 
ation has a superficial area of eleven square miles, five hundred 
and seventy-seven acres, and a thickness of froin a few feet to
