30 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1911. 



The total number of visitors to the older Museum building was 207,010, to 

 the Smithsonian building 167,085, and to the new Museum building 151,112. 

 Cousidering that the buildings have been opened only during working hours 

 on week days, this is to be regarded as a fair attendance. That it was smallest 

 at the new building was owing to the fact that less than one-sixth of the 

 exhibition space had been made ready for the public. 



The publications issued comprised the annual report for 1910, two volumes 

 of Proceedings, five bulletins, one volume of Contributions from the National 

 Herbarium, and a large number of separate papers belonging to three unfin- 

 ished volumes of Proceedings and two of Contributions. With the exception 

 of the annual report, all were descriptive of material in the Museum collections. 

 The number of copies of the various publications distributed was over 110,000. 



By the addition of 6,127 books, pamphlets, and periodicals, the Museum 

 library was increased to 40,211 volumes and 66,074 unbound publications. 



The auditorium in the new building was used on several occasions for meet- 

 ings of important scientific bodies. The sessions of the First American Inter- 

 national Humane Congress, in connection with which an interesting exhibit 

 was installed, were also held here from October 10 to 15, 1910. 



The position of head curator of the department of biology, made vacant by 

 the designation of Dr. F. W. True as an Assistant Secretary of the Institution 

 on June 1, was filled by the appointment of Dr. Leonhard Stejneger. curator 

 of reptiles and batrachians. For convenience of administration, the divisions 

 of invertebrate paleontology, vertebrate paleontology, and paleobotany were 

 combined, under the title of sections, in a single division of paleontology, with 

 Dr. R. S. Bassler as curator. 



Respectfully submitted.

 Assistant Secretary in Charge, U. 8. National Museum.
