 but the principles of the system in both places can be identical. 



At the outset the museum system consists of the physical constants, the 

 educational aim and Xho. government, the administration. The physical constants 

 are : (1) The Museum Building, (2) the Museum Hall, (3) the Museum Case. It

The position of a museum involves important consequences in the large cities. 

 It should be accessible from all quarters of a community, it should be placed 

 where least likely to incur accident or destruction, it is preferably built upon an 

 elevation than in a hollow, its surroundings should minister to the pleasure of the 

 eye and involve an expression of distinction and beauty. 



As one of the deteriorating agencies, accompanied sometimes with very seri-
