FOSSIL VERTEBRATES 
of extinct animals executed for the Museum under the direction of 
Professor Osborn and provided for by Mr. J. Pierpont Morgan. These 
restorations have been a most successful and generally attractive 
phase of the work of the Department. 
Since 1902 Mr. S. H. Chubb has been engaged, in connection with 
the evolution of the horse studies, in the collection and preparation of 
the material illustrating the osteology of the modern horse. A splen- 
did series of mounted skeletons and preparations of skulls are the 
result of the work. 
The collections of the Department afford unsurpassed opportunities 
for research in this branch of science. Many preliminary and a few 
monographic studies have been completed and others are in progress. 
The pubhshed studies include two volumes of Memoirs (Vols. I and 
IX) and 119 articles in the American Museum Bulletin from 1892 to 
1909, besides miscellaneous articles in other publications, by Professor 
H. F. Osborn, Professor Bashford Dean, Dr. J. L. Wortman, Dr. O. 
P. Hay, Dr. W. D. Matthew, Mr. Barnum Bro^\'n, Mr. Walter Granger, 
Mr. J. W. Gidley, Dr. L. Hussakof, Mr. Charles Earle, and Mr. W. K. 
Gregory of the Museum Staff, and Dr. F. B. Loomis, Dr. J. H. McGregor, 
Dr. E. C. Case, Mr. Earl Douglass, and Dr. W. J. Sinclair.
