28 ANNUAL REPORT OF THE 



The Assistant has been occupied during the greater part of the 

 year with routine work and with the publication of the results of 

 his studies of Palaeozoic fish-remains belonging to this and other 

 institutions. Several advantageous exchanges have been made, 

 and a considerable quantity of material has been received by gift 

 or purchase, as will be noted in the following list of accessions. 

 Material has also been loaned for study, Professor Osborn having 

 borrowed all of our better preserved titanothere skulls, and some 

 reptilian remains belonging to the Whitney Collection having 

 been sent to Dr. J. C. Merriam, of California University. The 

 collections have been consulted a number of times by students 

 from other institutions, and thanks are due in particular to Dr. 

 George F. Eaton, of Yale, for his aid in working up our large rep- 

 resentation of Triassic fishes. Of the latter, very extensive col- 

 lections were made by the New Jersey Geological Survey in the 

 vicinity of Boonton, New Jersey, and placed at the disposal of this 

 Museum by Dr. H. B. Kummel, Director of the Survey. 



At the late meeting of the Geological Society of America the 

 Assistant was appointed a delegate to represent the Society at 

 the Hugh Miller Centenary to be held at Cromarty, in connection 

 with which a visit to the leading Old Red Sandstone localities 

 in Scotland is contemplated. The Assistant expects to remain 

 some further time abroad, having for his primary object the study 

 of the principal foreign collections of fossil fishes.
