ing from persistent pulps, as in Rodents. The adult dentition is 

 as follows : — Incisors f ; canines x ; premolars f ; molars fj. 

 The articulation of the lower jaw with the skull corresponds to 

 that in Ungulates. The posterior nares open behind the last upper 

 molars. The brain was small, and somewhat convoluted. The 

 skeleton most resembles that of Carnivores, especially the UrsUke, 

 but the scaphoid and lunar bones are not united, and there is a 

 third trochanter on the femur. The radius and ulna, and the tibia 

 and fibula are distinct. The feet are plantigrade, and each had five 

 digits, all terminated with long, compressed and pointed, ungual 

 phalanges, somewhat similar to those in the bears. The other 

 genera of this order are less known, but all apparently had the 

 same general characters. There are two distinct families, TiUo- 

 tTieridce, in which the large incisors grew from persistent pulps, 

 while the molars have roots ; and the Stylinbdontidce, in which all 

 the teeth are rootless. Some of the animals of this group were 

 as lfrrge as a tapir. With Hyrox or the Toxodontia the present

Clay-balls as Slung Shot or Cooking Stones. — Round 

 balls of clay as hard as that material could be made were seen 

 in the museum of Nassau, N. P., labelled from a cave in the 

 Islands. These might be used for two purposes, as they were 

 round and the size of a hen's egg ; first, their size and shape fitted 

 them for a weapon of warfare, if wrapped in buckskin or hide 

 drawn very tight over it and fastened, leaving a loose end. which, 

 being firmly fastened over a strong stick, forms a formidable slang 

 shot. The Apache Indians make and use the same kind of im- 

 plement, which they use in battle, only their balls are of stone. 

 The second use to which they might be applied is in cooking. After 

 being heated very hot they were probably placed in the substance 

 to be cooked, then taken out and this operation repeated until re- 

 quired no more. The ancient Indians of the Bahamas made 

 pottery, as pieces found testify, therefore they could cook in ves- 

 sels of pottery when stationary, but if travelling, it would be in- 

 convenient to carry them, as they easily break; but they could 

 make deep baskets, or trays of twigs, or leaves of the palm-trees 

 so tight that they held water ; thus, by putting water with whatever
