 the two upper stories of the building known as the Arsenal and such

 of the collections deposited by the American Museum, and shall cause 

 them to be furnished with glass cases suitable for the preservation and 

 exhibition of such collections. 



Second — The Trustees of the American Museum to employ their own 

 Curators for the care and arrangement of their collection, and to pay 

 them their salaries, all such persons to be subject to the regulations of 

 the Park Commissioners. 



Third — The Police force for the protection of the property and the em- 

 ployees for the cleansing and general care of the rooms to be employed 

 and paid by the Park Commissioners. 



Fourth — The Trustees and Curators of the American Museum to have 

 free access at all reasonable times to the rooms occupied by their collec- 

 tions. 



Fifth — The collections so deposited to be exhibited to the public at 

 least three days in the week in the name of the American Museum of 

 Natural History, the Trustees to have the right to close the collections 

 at such times as shall be necessary for the arrangement and rearranging 

 of the specimens, subject to the regulations of the Park Commissioners. 



Sixth — The collections already acquired, and those which may from 

 time to time be acquired and so deposited, to remain the property of the
