254 The American Geologist. October, 1903. 
Other effects of the continental ice-sheet and its drift deposits, in 
changing the courses of drainage tributary to the Ohio river and lake 
Erie, are also described and mapped. 
This paper, with its admirable illustrations, is an important con- 
tribution to glacial geology, and reflects much credit on the local society 
by which it is published. (A second geological paper in this volume 
contains records of the earliest use of the anthracite coal of Pennsyl- 
vania, by blacksmiths about the year 1770, and in grates for domestic 
heating in February, 1808.) w. u. 
More Concerning the Lansing Skeleton. By Luella A. Owen. The 
Bibliotheca Sacra, vol. LX, pp. 572-578, July, 1903. 
The author thinks that the loess never filled the Missouri valley to 
the level of the inclosing terraces and bluffs. Her review of the dis- 
covery of the Lansing skeleton, and of the discussions concerning its 
geologic situation and antiquity, indicates the need of further studies of 
the origin and deposition of the loess, until geolosists shall reach a bet- 
ter agreement. After noticing the numerous papers on this subject, a 
conclusion is given as follows : 
"Professor Winchell's elaborate study of the deposits would seem 
to demonstrate the existence of glacial man in the Missouri valley be- 
yond all intelligent controversy. On the banks of the Missouri, as on 
those of the Little Miami and of the Delaware farther east in America, 
and on the Dnieper in Russia, man was a witness to those great and 
rapid changes of terrestrial conditions connected with the closing stages 
of the Glacial period ; thus anew raising glacial geology to a most im- 
portant rank among the historical sciences." w. u. 
Guelph Fauna in the state of New York, John M. Clarke and Rudolf 
Ruedemann Memoir 5, New York State Museum, Albany, N. Y., 
1903. 
This volume gathers into one presentation what is known of the 
Guelph fauna of New York. The Guelph seems to extend from far 
north and northwest in Canada through Ontario to New York state. It 
is also found in northern and southern Ohio, in Illinois, Wisconsin and 
in Iowa. Its westward extension is not known, but it probably does not 
continue far west of the Mississippi river. 
The authors, following Hall, consider the Guelph as a period of in- 
cipient desiccation introductory to the salinity of the more complete iso- 
lation exhibited by the Salina; marked by numerous corals and coral 
reefs, by large and heavy shells and by fewness of lamellibranchs and 
brachiopods. 
Discovered first by Hall, in New York, it was nam;d in Canada by 
Bell, where its development is greater. 
We notice that in discussing the Guelph of Illinois, the authors have 
failed to mention the "Enumeration of fossils collected in the Niagara 
limestone at Chicago, Illinois with descriptions of several new species," 
by Prof. A. Winchell and Prof. O. Marcy (Mem. Boston Society Nat. 
History, vol. I, pp. 81-112, with two plates of fossils, 1865). These
