REPORT OF THE PROFESSOR OF INVERTEBRATK 

 PALEONTOLOGY. 



The Professor of Invertebrate Paleontology respectfully 

 reports, that during the year he has delivered a course of twenty- 

 seven lectures (with practical demonstration) on paleontology, 

 which, as heretofore, has been attended largely by teachers of the 

 various city schools. A special course on geology, arranged at 

 the request of the Teachers' Institute of Philadelphia, was also 

 delivered in the Hall of the Academy, as a continuation of a similar 

 course given before the same body in the spring and autumn of. 

 1884. The attendants at these lectures numbered between 100 

 and 150. Both courses of instruction in the class-room were 

 supplemented by a number of field excursions in the region about 

 Philadelphia, ranging to Orange, N. J., and the Atlantic coast, 

 and by a twelve days' trip to the Valley of the Upper Delaware. 



The collections of the Academy in the department of Inverte- 

 brate Paleontology have received no very material accessions 

 during the 3 r ear; special mention may be made of a beautiful 

 slab of crinoids, from the Carboniferous Limestone of Iowa, gen- 

 erously given to the Society b} T Mr. Charles Wachsmuth, whose 

 important papers on the Paleocrinoidea, prepared in conjunction 

 with Mr. Springer, are being published in the Proceedings of the 

 Academy. 



Through a re-arrangement of the collections contained in the 

 Museum opportunity has been afforded for the proper arrange- 

 ment and display of the collections illustrating European paleon- 

 tology, which have up till now been largely inaccessible and 

 placed in drawers. The proper identification and labeling of 

 species will, however, be a matter of time. 



Very respectfully, 



Angelo Heilprin, 

 Prof, of Invertebrate Paleontology.
