Central Hall. 



The two wall-cases of Bay, No. II., on the left side of the 

 hall, have been arranged so as to show, in a synoptical manner, 

 the generally recognised Orders and Sub-orders of existing 

 Mammals by examples selected to illustrate the predominating 

 characters by which they are distinguished. A brief popular 

 account of the characteristics of the group, and a map 

 showing its geographical distribution, is placed with each.
