1896.] NATURAL SCIENCES OF PHILADELPHIA. 589 



REPORT OF THE PROFESSOR OF GEOLOGY. 



The Professor of Geology respectfully reports that, as in former 

 years, he has delivered the usual course of spring lectures, accom- 

 panied by Saturday field excursions. It is gratifying to be again 

 able to state that the interest in the study of geology, as evidenced 

 by the attendance at the lectures and participation in the excur- 

 sions, shows no diminution, but the reverse. In addition to the 

 regular Academy course, a special course of six lectures, introduc- 

 tory to the study of rocks and minerals, was delivered under the 

 auspices of the Ludwick Institute, the attendance at which was sig- 

 nificantly large. 



In his capacity of Professor of Geology, the undersigned was ap- 

 pointed by the Council and Academy to represent the institution 

 at the Millennial Mining and Geological Congress held at Budapest, 

 Hungary, on September 25th and 26th. A report of this mission 

 has been presented to the Council. The report makes reference to a 

 special journey in the north of Africa, where a superficial study was 

 made of the rock formations of the Atlas Mountains, with particular 

 reference to the determination of the existence of glacial phenomena 

 such as had been alleged to be found there. No evidences of past 

 glaciation could be detected. As a result of this journey, a fairly 

 extensive and representative collection of fossils was obtained from 

 the Atlas confines of the Sahara ; these, when properly studied and 

 determined, will be placed with the collections of the Academy. 



The additions to the Academy's geological collection made dur- 

 ing the year have been neither particularly large nor important, the 

 most noteworthy, in the department ot Paleontology, being the ani- 

 mal remains obtained from Port Kennedy, Pa., by Mr. H. C. Mer- 

 cer. 



Respectfully submitted, 



Angelo Heilprin, 

 Prof, of Geology. 



REPORT OF THE PROFESSOR OF ETHNOLOGY AND 



ARCHEOLOGY. 



I have the honor to report that, during the year 1896, 1 delivered 

 a course of six lectures, public and gratuitous, on subjects connected 

 with the study of anthropology. They were well attended and in- 

 creased the general interest in this branch of science.
