18 ANNUAL EEPOET SMITHSONIAN INSTITUTION, 1910. 



During the } r ear the following American biologists were appointed 

 to the Smithsonian Table : 



Prof. H. D. Senior, of the College of Medicine of the Syracuse 

 University, who continued his researches in the angioblast of the 

 trunk in Teleosts through studies of the origin of the circulation in 

 Amphioxus. 



Dr. R. M. Strong, of the University of Chicago, whose work was 

 confined to some general studies of chromatophores, which occur in 

 two species of Cephalopods and in three species of Crustacea. 



Dr. W. D. Hoyt, formerly of Johns Hopkins University, but now 

 of Rutgers College, whose studies comprehended the periodicity in 

 the fruiting and cultural experiments in alternations of generations 

 of marine algae. 



Prof. Charles L. Edwards, of Trinity College, who continued his 

 investigations in the variations in Synapta inhoerens and other holo- 

 thurians. 



Prof. Charles TV. Greene, of the University of Missouri, who 

 worked on the comparative physiology of fishes. 



Applications for future occupancy of the Table have been received 

 during the year from Dr. S. R. Williams, of the Miami University, 

 and from Dr. Sergius Morgulis, of Harvard University. 



The advisory committee on the Smithsonian Table has, as always, 

 rendered invaluable aid in the examination of the credentials of ap- 

 plicants, and it is desired to here record the Institution's apprecia- 

 tion of their assistance. 



During the year an important change in the personnel of the com- 

 mittee took place. Dr. John S. Billings, who served for many years 

 as its chairman, tendered his resignation, and it is much regretted 

 that a relationship so helpful and agreeable has been thus terminated. 

 The Institution is fortunate, however, in securing the cooperation of 

 Dr. Carl H. Eigenmann, professor of zoology at the Indiana Univer- 

 sity and director of the biological station maintained in connection 

 with that establishment. The present organization of the committee 

 is as follows: 



Dr. Theodore Gill, of the Smithsonian Institution, chairman; Dr. 

 C. TVardel! Stiles, of the Bureau of Public Health and Marine-Hos- 

 pital Service, secretary; Dr. E. B. Wilson, of the Columbia Univer- 

 sity, New York ; Dr. Carl H. Eigenmann, of the Indiana University. 



PUBLICATIONS. 



The principal medium for carrying out one of the fundamental 

 functions of the Institution, " the diffusion of knowledge," is through 

 its publications. The Smithsonian Contributions to Knowledge, the 

 Smithsonian Miscellaneous Collections, and the Smithsonian annual
