Academy the free use of the Cabinet Hall and other rooms 

 suitable for the purposes of the Academy in the Dispensary 

 Building of the St. Louis Medical College (also known as 

 Pope's College). This generous offer was thankfully ac- 

 cepted. In this building, which was located on the northeast 

 corner of Seventh street and Clark avenue, were established 

 the first museum and library of the Academy. 



At that same meeting the first donations were received. 

 Dr. Albert C. Koch presented a lithographic plate of the 

 " Missourium " (Mastodon giganteus) found by him in Mis- 

 souri, and which played an important part for some time in 

 archaeological and geological discussions in this country. Mr. 

 Charles P. Chouteau, who had then in his posession a large 

 number of fossils collected by Dr. F. V. Hayden from the 

 Bad Lands of Nebraska, placed this collection in the museum 

 of the Academy. His own interest in the collection, amount- 

 ing to about one-fourth of the whole, he presented as a dona- 

 tion to the society. 



Through the liberality of Mr. Charles P. Chouteau the 

 Academy came in possession of an extensive and beautiful 

 collection of mammalian remains from the Eocene Tertiary, 

 together with many finely preserved fossils from the Creta- 

 ceous Formation of Nebraska. This collection, which was 

 the nucleus of the Academj^'s Museum, was later increased 

 by the purchase of the one-fourth interest of Col. A. J. 

 Vaughan, which gave to the Academy an equal share with the 

 Academy of Natural Sciences of Philadelphia in the splendid 

 collection made by the United States Geological Survey of 

 the Territories from the Bad Lands of Nebraska and other 

 portions of the Upper Missouri Country. Unfortunately 

 almost the entire collection was lost in the great fire which 

 the Academy suffered some years later. 



At the same meeting Dr. Koch offered to visit, for the 

 benefit of the Academy, a certain locality in Mississippi, 

 where remains of Zeuglodon^ a gigantic fossil whale, had been 

 discovered. This was the first investigation carried out at the 

 expense of the new Institution. 



At the third meeting of the Academy the first donations
