Editorial. 



The work accomplished at the Museum during the months which 

 have elapsed since the appearance of the last number of the Annals 

 has been of great interest, and in much of it foundations have been 

 laid for the publication of scientific papers which will undoubtedly add 

 to the sum of knowledge in relation to many matters of interest. 



'I'he results of the field work done by the various parties engaged in 

 carrying on explorations in the region of the Rocky Mountains are 

 represented by the accession to the paleontological collections of the 

 Museum of three carloads of crates containing vertebrate fossils. The

 portions of this vast mass of material from the matrix. The revela- 

 tions that are made as the work proceeds in relation to the osteology 

 of the reptilia and mammalia collected are of the highest interest. 

 Professor Hatcher has well in hand a memoir upon some of the mam- 

 malian material, and the present number of the Annals contains a 

 valuable paper from his pen upon the structure of the forelimb and 

 forefoot of Brontosaurus, based upon the excellent material obtained 

 by Mr. C. W. Gilmore at Camp Carnegie in Wyoming. Other im- 

 portant papers are in process of preparation. 



The Museum has acquired by purchase the entire collection of in- 

 sects made by Mr. Herbert H. Smith during his several journeys in 

 Brazil and elsewhere in South American countries. Portions of these
