THE SMITHSONIAN INSTITUTION AND ITS 

 AFFILIATED BUREAUS. 



A LETTER from Professor Franz Boas 

 concerning the Bureau of American Eth- 

 nology, published in this issue of Science, 

 calls attention anew to the unsatisfactory 

 status of the bureaus of the Government 

 under the supervision of the Smithsonian 

 Institution. The anomaloiis relations 

 which the National Museum has long sus- 

 tained to the Smithsonian Institiition were 

 considered at length in Science, N. S., 

 Vol. v.. No. 106, January 8, 1897. The 

 conclusions reached in that number of the 

 journal are summed up in the following 

 paragraph : 



"There is no logical connection between 

 the Smithsonian Institution and the Na- 

 tional Museum. The museum is a most 

 important institution; it is now well es- 

 tablished; its maintenance is demanded by 

 the people, and it will thrive under a com- 

 petent director, responsible only to Con- 

 gress or to the head of some department 

 under which it could properly be placed. 

 The usefulness of the Smithsonian Insti- 

 tution will be increased by the diminution 

 of burdensome administrative duties which 

 were never contemplated in its original
