specimens of erratic boulders gathered by the late Dr. Arnold Guyot 

 during his studies of the glaciers of Switzerland. Typical rocks and 

 fossils represent the stratigraphic series described by the geological 

 surveys of New Jersey and New York. A collection of minerals, 

 chiefly crystals, bequeathed to the university by the late Archibald 

 MacMartin of New York, is noteworthy because of the perfection of 

 the specimens and the number of localities represented in each species. 

 The collections in economic and structural geology and petrology 

 stand in tray racks in the laboratories, are designed chiefly for use 

 in laboratory instruction, and to that end are arranged in accordance 

 with the systems adopted in the text-books used. The series illustrat- 

 ing the courses in structural geology and economic geology from the 

 theoretical point of view are especially interesting. 



Paleontology. Invertebrates, on exhibition, 7ooo±, in storage, 

 ioo,ooo±, types and figured specimens, 400; Vertebrates, on exhibi- 

 tion, 1000+, in storage, 3ooo±, types and figured specimens, 5oo±; 

 Plants, on exhibition, iooo±, in storage, 5ooo±, types and figured 

 specimens, ioo±. The collections include skeletons of a mastodon, 

 an Irish deer, a cave bear, and some of the extinct birds of New Zeal- 

 and, as well as the skulls of Uintatherium and a remarkably complete 

 and unique skeleton of Cervalces from northern New Jersey. A synop- 

 tic collection of vertebrate and invertebrate fossils from North America 

 and Europe illustrates the principal organic forms of the geological 

 epochs. Included in this series are the tertiary fossils, many of which 

 are type specimens, gathered in the West by the various Princeton 

 expeditions. An extensive series of fossil insects and plants from the 

 oligocene shales of Florissant, Colorado, includes many of the types 

 described by Lesquereux. 



Among recent acquisitions there are extensive series of miocene 

 fossils from Yorktown, Virginia; collections illustrating the strati- 

 graphic paleontology of the Appalachian region; and the collections of 

 vertebrate and invertebrate fossils secured by Hatcher and Peterson 

 from miocene strata of Patagonia, now being studied and described by 

 several authors in the reports of the Princeton University expeditions 

 to Patagonia, edited by Professor William B. Scott and published by 

 the university. The paleobotanical material is enriched by the Mans- 

 field collection of carboniferous plants from Pennsylvania. 



Zoology. These collections are especially rich in osteological and 

 ornithological material. The former includes a large number of 

 mounted and disarticulated skeletons of fishes, reptiles, birds, and mam- 

 mals. The collections of mounted and unmounted bird skins include
