much to the interesting exhibit illustrating the evolution of the 

 locomotor apparatus from fish to man, which is now in progress. 



Mr. R. W. Miner has continued his work on the skeleton and 

 musculature of the primitive amphibian Eryops. He is carrying 

 on this work outside of museum time, and although it has been 

 greatly interrupted by other duties, solid progress has been made 

 during the past year, and it is now nearing completion. 



Dr. D. J. Morton, an orthopaedist, has made a thorough com- 

 parative study of the mechanics of the feet of man and the 

 anthropoid apes and monkeys. This research is revealing much 

 concerning the origin and evolution of the human foot. 



Dr. Milo Hellman has completed a reconstruction of the 

 palatal arch of the Talgai man, a subject which has an im- 

 portant bearing on the relationships of this ancient proto- 

 Australian type. He has also assisted in many ways in 

 conferences on the dentition of men and of anthropoids. 



Professor J. H. McGregor visited many museums in Europe 

 and brought home a vast amount of detailed information and 

 stereoscopic photographs bearing on the anatomy of prehistoric 

 races, as well as a large collection of casts of skulls and of 

 cultural objects. He has made gratifying progress towards the 

 completion of his reconstruction of the skeleton of the Neander- 

 thal man and of the braincast of Pithecanthropus. 



The Curator completed his work on the "Origin and Evolu- 

 tion of the Human Dentition," and with the) assistance of Mrs. 

 M. H. Fink the book was finally made ready for the press. The 

 paper on the classification of the various races of mankind, 

 undertaken at the request of President Osborn, has recently 

 been completed. 



The Department has also been in touch with several investi- 

 gators, such as Dr. J. Leon Williams, and has been able to 

 supply them with material or to assist in their researches. 



Thanks to the generosity of Mr. Childs Frick, the Museum was 



enabled to take advantage of the researches of Mr. A. S. Romer 



„ on the evolution of v the skeleton of early verte- 



Exhibition . . , . , . . , , 



brates, and to secure his services to make a series 



of models illustrating the successive stages of evolution from the 



primitive Devonian fish, Eusthenopteron, to man. Mr. Romer 



has completed the model of Conodectes, one of the most
