THE MUSEUM. 



mineralogical and blowpipe instruction, 

 with desks and a students' cabinet of 

 minerals. 



The second floor is given up to geo- 

 logy and palaentology. The southern 

 room contains vertebrate fossils. The 

 latter are mostly collections made by 

 Prof. Marsh, in the Rocky Mountain 

 regions and other parts of the West. 



In this room a case contains speci- 

 mens of toothed birds, discovered by 

 Prof. Marsh in the cretaceous rocks of 

 Kansas. 



Nearby, in a case against the wall, 

 are the bones of a large mastodon 

 from the Post-Plioclen of southern 

 New York. In the ne.xt case are the 

 huge bones of the Miocene Bronto- 

 tlieridac from Dakota and Nebraska. 

 In another case are the remains of the 

 Dinoccrata, large horned mammals 

 from the Eocene of Wyoming. Then 

 comes a case containing two skeletons 

 of gigantic Moas (Dinornis), extinct 

 birds from New Zealand. In the cen- 

 ter of the room are part of the bones 

 of an enormous Dinosaur, sixty feet in 

 length, from the Jurassic of Wyoming, 

 and a large slab, standing vertically, 

 showing the skeleton of a Mosasaur 

 from the Chalk of Kansas. There is 

 also a case containing the bones of the 

 feet of the three-toed and four toed 

 horses from the Tertiary of Nebraska 

 ^nd Kansas. 



The Western exhibition room is oc- 

 cupied mainly by a collection of inver- 

 tebrate fossils, arranged zoologically. 

 The first vertical case on the south is 

 devoted chiefly to fossil sponges. Then 

 follow two cases with corals, with 

 many fine examples from Kentucky, 

 Ohio and New York. The nine suc- 

 ceeding cases contain collections of 

 crinoids, trilobites, Crustacea, bryozoa, 



and fossil shells. One case contains 

 many type specimens illustrating the 

 structure and development of the tril- 

 obite. Two large wall cases on the 

 eastern side of the room exhibit slabs 

 and tablets of crinoids, mostly from 

 Indiana. A third wall case encloses a 

 large slab measuring four by six feet, 

 showing nearly thirty species of fossils 

 represented by upwards of one hundred 

 and forty individuals. The museum 

 also has an extensive collection of 

 brachiopods. 



Of the large collection of foot-prints 

 belonging to the university, only a few 

 fine slabs are on exhibition, part of 

 them in each of the two exhibition 

 rooms of the second story. One of 

 the most interesting is a slab about 

 twelve feet long, covered throughout 

 with raindrop impressions, and, be- 

 sides these, two series of foot-prints of 

 biped reptiles, one line of them extend- 

 ing the whole length of the slab. 



The third story is occupied with the 

 zoological collections, so far as there 

 is room for their exhibition. The gen- 

 eral zoological collection occupies • the 

 western room. The specimens are 

 well arranged for exhibiton and all 

 labelled. Facing the south door 

 stands a case devoted to the sponges, 

 among which are many species of the 

 siliceous or glass sponges. Beyond 

 the sponges, twelve cases are filled 

 with the collection of corals, which is 

 one of the most extensive in the coun- 

 try. These are followed by the Echin- 

 oderms, etc. Several cases are de- 

 voted to a collection of the marine 

 invertebrates of New England, which 

 is nearly complete. Other cases con- 

 tain special collections of the shells 

 and corals of the Pacific coast of Am- 

 erica; of the corals of Bermuda; of
