FIFTY YEARS OF THE AMERICAN 

 MUSEUM OF NATURAL HISTORY 



It has become necessary to postpone the 

 celebration of the fiftieth anniversary of the 

 charter of the museum for five years, namely, 

 imtil 1924. It is hoped that this celebration 

 may be marked by the completion of the en- 

 tire southern half of the mu-seum, as planned 

 between 1870 and 1875. as the year 1924 will 

 mark the period of half a century since the 

 building was actually begun by the City of 

 New York. 



In the meantime at the request of the 

 editor of Science, there is here presented a 

 review of certain aspects of the development 

 of the institution during its first fifty years, 

 based on the Annual Report of the president 

 to the trustees. 



The American Museum has broken away 

 from many old museum traditions and cus- 

 toms and has been constantly striking out 

 along new lines in every branch of its activity. 

 In exploration, while making North America 

 our chief concern, we have reached out into 

 South America, Africa, Asia, and. in certain 

 branches, into Europe itself. The natural 

 history of our new colonial wards, the Philip- 

 pines and Porto Eico, are matters pf intimate 

 concern. In South America, through a series 

 of expeditions we are exploring every part of 

 the continent and have established most 

 cordial personal as well as scientific relations. 



This is in keeping with the world-wide ex- 

 tension of American interests and influence 

 and is part of the inevitable participation of 

 America in the world's affairs. Neither the 

 American iluscum, nor our government, nor 

 our ptoople can remain isolated or bound by 

 the confines of our own continent. Thus, 

 while more than ever an American Museum, 

 our institution has become a world museum. 

 In increasing degree it is bringing all parts 

 of the world within the view of die millions
