478 RESEARCH IN CHINA.

Léczy, Ludwig von: Die wissenschaftliche Ergebnisse der Reise des Grafen Béla Széchenyi in Ost- 
asien, 1877-1880. Vol. 1, part 3. (First edition in Hungarian, 1890.) 
In setting forth the results of his extensive geologic explorations in China, Mongolia, 
and Burma, Herr Léczy names and briefly describes rocks from many localities. Detailed 
petrographic descriptions of a number of these were afterwards prepared by Dr. A. Koch, 
as mentioned below. 
1895. 
Steuer, A.: Mittheilungen uber Gesteine aus den Chinesischen provinzen Kansu, Schensi, Hupe, und 
Honan. Neues Jahrbuch fiir Min., Geol., und Pal. 1895, x. 
The author gives a brief description, based on microscopical study, of seventy-three 
rocks collected in the northwestern part of China by Herr Michaelis. Very little mention 
is made in this paper of the geological occurrence of the rocks and their relationships to 
each other.

Koch, Anton: Die wissenschaftliche Ergebnisse der Reise des Grafen Béla Széchenyi in Ostasien, 
1877-1880. 
In this report (Vol. m1), Dr. Koch describes the more important types of rocks col- 
lected by Herr Ludwig Léczy, in the provinces of Hu-pei, Shen-si, Kan-su, Kokonor, and 
Ssi-ch’uan. The descriptions are rather brief and are usually generalized from several 
specimens. Little information is given regarding the geologic relations of the rocks in the 
field. The report enumerates 152 specimens, but a much smaller number has been actually 
described. Nevertheless, the fact that modern microscopical methods have been used, 
renders this one of the most valuable contributions yet made to our knowledge of the 
rocks of China. 
Lorenthey, E.: Same report, III. 
A number of specimens of limestones are described, special attention being given to the 
fossil foraminifera contained in them.

Vogelsang, Karl: Petermann’s Mittheilungen, 1901, pp. 241-250. 
This report on several journeys in northern and central China contains only brief 
characterizations of the various rocks observed.

Vogelsang, Karl: Petermann’s Mittheilungen, 1go4, p. 11, et seq. 
The writer gives an account of a journey made in 1900, north, west, and south from 
I-chang-fu in Hu-pei by way of Chu-chi-hién, the Nan-kiang, and the Ta-ning-ho to Wu- 
shan on the Yang-tzi. He names the rocks observed en route and describes a few of them 
briefly on the basis of microscopic study.

Lorenz, Theo.: Beitrige zur Geologie und Palzontologie von Ostasien, Marburg, Teil I. 
This paper describes the geology of portions of the province of Shan-tung and inci- 
dentally it contains brief descriptions of several igneous and metamorphic rocks from that 
province. The author discusses at somewhat greater length the origin of the peculiar 
oolitic and conglomeratic limestones of the Cambrian terranes.
