MISCELLANEOUS. 



The attendance of visitors to the Natural History Building dur- 

 ing the year aggregated 364,281 for week days and 103,018 for 

 Sundays, being a daily average of 1.167 for the former and 1,981 for 

 the latter. At the Arts and Industries Building the total attend-

 of bulletins, 5 parts of Contributions from the National Herbarium, 

 and 51 proceedings papers. The total number of copies of publica-

 and Dr. W. H. Dall, the former contributing the scientific library of 

 the late Joseph Paxson Iddings, petrologist.
