hibemicus), together with a cast of the skull of Piprotodon (an 

 Australian mammal), the skull and lower jaw of a young Mastodon, 

 and the lower jaw of the St. Catharine's Mastodon, which is interest- 

 ing from preserving the smaller tusk in the lower jaw. 



The Megaceras is mounted in the centre of the room, and presents 

 a very fine appearance ; while the casts of other European and Asiatic 

 fossils are arranged on the east side of the centre. This arrangement 

 gives us, on the west or left hand side, as we enter the room, a North 

 American, the central part a European and Asiatic, and the eastern 

 end a South American gallery, chiefly of the larger Mammalia of 

 the Pleistocene period. This plan, with the comparatively small 

 number of species which we are able to represent, makes a much 

 more satisfactory and instructive arrangement than any other which 

 we could adopt. In the same gallery with the Cohoes Mastodon, I 

 propose to arrange all the remains of Mastodon and Elephant which 

 we have or may obtain from the North American continent. The 

 greater part of those we possess are already thus arranged, while 

 others, which require some preparation, will soon be placed in the 

 same position. 



I would suggest the propriety of procuring for the European gal- 

 lery, a skeleton of the Cave Bear and a few other things of the same 

 geological age, sufficient to give an expression of the fauna of that 

 period. A few other objects from the South American fauna of the 

 same age would add greatly to the interest of the gallery upon that 

 side. 



The plan for the disposal of the remaining casts of the Wadsworth 

 gallery, in proximity to the South American gallery, will essentially 

 preserve the unity and integrity of that liberal gift to the museum,- 

 and be quite satisfactory to the donor. 



The removal of the Wadsworth gallery from the first floor of the 

 museum greatly enlarged the area for the collections of Geology and 

 Palaeontology, illustrating the New York series, and has enabled me 

 to carry out the plan I had proposed for the arrangement of this 

 important part of the museum. By this means we are enabled to 

 add six table cases of twelve and a half feet in length for the. 

 Palaiontological collections, and an extent of about thirty feet of table 

 cases for the Geological series, which will give room for a very satis- 

 factory arrangement of the entire Palaeozoic series. 



In the Palseontological series the cases have already been added, 

 and the entire collection rearranged and extended to conform to the
