of domesticated animals ; a selection from this material will be 

 utilized for the new room. 



Dr. C. B. Davenport, Mr. E. N. Fischer, Mr. F. P. Lothrop,and 

 Mr. H. F. Otis have shown their interest in this exhibit by pre- 

 senting a number of fowls and pigeons ; these have been mounted 

 by the Museum preparator, Mr. George Nelson. 



For exhibition among the special collections Dr. W. E. Castle 

 has presented a series of fourteen guinea-pigs ; this series, which 

 shows graphically the principle of alternative inheritance, has 

 been most skilfully mounted by Mr. Nelson. 



Mr. Nelson has continued his work on the reptiles for exhibi- 

 tion ; two of the more noteworthy examples of his handiwork are 

 the Python and the Cobra in the Indian Room. 



There are 42,421 volumes and 36,322 pamphlets in the Library 

 of the Museum, an increase of 1,264 volumes and 1,289 pamphlets 

 over the numbers previously reported. 



The publications for the year are listed on pages 34-35 ; these 

 include a volume and two numbers of the Memoirs, seventeen num- 

 bers of the Bulletin, and the Annual Report, a total of 893 (731 

 octavo, 162 quarto) pages and 161 (51 octavo, 110 quarto) plates. 

 Four of the numbers of the Bulletin and all of the Memoirs are 

 reports on the scientific results of expeditions fostered by Mr. 

 Agassiz ; seven numbers of the Bulletin are based principally 

 upon Museum collections, three numbers are Contributions from 

 the Zoological Laboratory, and three numbers, issued in the 

 Geological series, are similar Contributions from the Geological 

 Department. The Corporation has continued an appropriation of 

 $350. 00 to assist in the publication of the Contributions from the 

 Zoological and Geological Laboratories.
