Botany and Zoology. 125 
12. Geological Excursion—Mr. Frank H. Bravtzy, a member of the 
Zoological and Paleontological Department of the Sheffield Scientific 
School, proposes to take charge of a few students, for the purpose of 
iving a practical introduction to geology, during a trip of about four 
weeks through the State of New York. 
He will meet his class at Burlington, Vt., on Monday, July 31st, and 
commence work on the following morning at Port Kent on the opposite 
side of the lake. 
The trip will include visits to some of the fine scenery for which New 
York is famous, as well as to characteristic and productive localities of 
nearly all the formations from the Potsdam sandstone to the Chemung 
group, for whose examination, within a small extent of country, the State 
affords the best opportunity in America, if not in the world. 
For some years past Mr. Bradley has been engaged in the study of 
the New York rocks and fossils, and has made quite extensive collections 
therefrom. We recommend him for the charge which he undertakes. 
Mr. B. informs us that the expenses while with him need not exceed 
one hundred dollars besides his fee of thirty dollars. 
Communications addressed to him at New Haven will be received as 
late as July 25th.
