of the Department of Zoology, and his acceptance of the post of 

 Honorary and Supervisory Curator of the same department, was an 

 important chanije in the scientific staff during the year. The change 

 was the result of the consideration of two years, and is intended to 

 give Mr. Elliot greater freedom of action with regard to his individual 

 work and movements, and at the same sime to retain to the depart- 

 ment, over which he has presided since the opening of the Museum, the 

 benefits of his scholarly attainments and wide Museum experience. 

 His successor as Curator of the department is Charles B. Cory, lately 

 of Boston, but now a resident of Chicago, who, since the inaugura- 

 tion of the Museum, has been the Curator of Ornithology. Orni- 

 thology now becomes a division of the department of Zoology, and 

 Mr. Cor^' becomes the curator of all the divisions and sections that 

 Would naturally come under Zoology. The personnel of the depart- 

 mental staff remains otherwise unchanged.
