Report of J. B. Perry, on Fossils and on the Library. 



In reporting progress at the end of the year, I find my time 

 so crowded with work, that I shall confine myself to simple re- 

 sults without entering to any great extent into details. 



During the first part of the year, considerable attention was 

 given to the fossil Corals. This was in the way of identifying 

 species, and perfecting the arrangement of the collection gen- 

 erally. Many of these corals were also cleansed, and partially 

 prepared to be mounted on tablets. In this labor I was aided 

 for four months, by an assistant. 



The work on Tertiary fossils, though somewhat interrupted, 

 has been carried forward for the most part, with a good degree 

 of success. I am happy to announce that the cataloguing of 

 the Gasteropoda, which was begun during the preceding year 

 has been nearly completed. The number of parcels of Tertiary 

 Gasteropods now entered on the catalogue exceeds 15,000. 

 While I was engaged in this work, a young lady was occupied 

 in writing the appropriate numbers on the different specimens, 

 or placing them in vials, when too small to receive the numbers ; 

 also in preparing tablets with labels, and otherwise assisting me. 



Most of my time, from the first of June to about the tenth of 

 November, was devoted to the more thorough arrangement 

 of given groups of Gasteropods ; to a revision of my previous 

 identifications ; to the preparation of tables containing the re- 

 sults reached, as to specific and generic designations, geologic 

 horizons, and the like ; and to the actual mounting of the 

 specimens, as thus prepared, on tablets. The work of mount- 

 ing has been shared by an assistant, who has been employed 

 during the remainder of the time in removing the soil from the 

 specimens, pasting labels on tablets, and helping me in various 

 other ways.
