80 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. 
Considering 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 aud 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.
