1 34 The American Geologist. August. i899 
PERSONAL AND SCIENTIFIC NEWS. 
Mr. O. H. Hershey proposes (Science. July 14, 1899) 
that the Spanish term rvJiwlino,^ common designation in the 
Republic of Columbia for the rounded cavities formed by 
rivers in their rock-beds be substituted for the English word 
pot-hole. 
Prof. C. E. Beecher has presented to Yale University 
his collection of invertebrate fossils, containing many type 
specimens, the whole numbering over one hundred thousand 
specimens, "in grateful recognition of the honors and favors 
conferred upon me during m}' connection with the Univer- 
sity." 
Dr. W. H. Hobbs, University of Wisconsin, has been 
made full professor of mineralogy in that institution. 
Dr. Henry Kummel, of the Lewis Institute, Chicago, 
has been appointed assistant state geologist of New Jersey. 
Dr. G. B. Shattuck has been promoted to the position 
of associate in physiographic geology at Johns Hopkins 
University. 
Dk. C. R. Eastman, of the Museum of Comparative 
Zoology, Cambridge, has advanced vol. I, part 2, of the 
translated and edited Zittel's Paleontology to such a stage 
that it can be published by September, at the latest. This 
part, which completes the first section of the work, brings 
the paging up to about 700, nearly 200 more than the origi- 
nal, and finishes the descriptions through insects. It con- 
tains a very large proportion of new, and especially Ameri- 
can, descriptions and figures; the Trilobites, for instance, 
having been entirely re-written by Beecher, and all the lat- 
est results of research upon them incorporated in the paper. 
Assistant Professor R. T. Jackson, of Harvard Uni- 
versity, has gone to Munich for the vacation months, to 
study the paleontological collections there.

mineralogy.

geology at the Ohio State University, Columbus. 
Mr. E. S. Riggs of the Field Columbian Museum is in 
the field near Medicine Bow, Wyoming, collecting fossil rep- 
tiles for that institution. He is assisted by Mr. H. W. 
Menke.
