78 Report of the President 



exchange. Especially noteworthy has been the acquisition of 

 185 volumes relating to exploration and discovery in the far 

 North; many of these works complete broken sets already 

 represented on our shelves, while others are rare and for the 

 most part out of print. In view of the prominent place the 

 American Museum of Natural History has occupied in northern 

 exploration, the expansion of this part of the Library is not 

 inappropriate. Another collection of similar size and especially 

 rich in east coast Mollusca has been added to our equipment, 

 an accession both necessary and important. 



During another year the Library has enjoyed the interest 

 and benefaction of Anson W. Hard, who has again found 

 it possible to present some of those rare and classic treatises 

 much needed by scientist or naturalist. Among these are the 

 following interesting and important works : Monograph of the 

 Coraciidce or Family of Rollers by H. E. Dresser; Sammlung 

 exotischer Schmetterlinge, 1806- 183 7, by J. Hiibner an ex- 

 tremely rare and highly prized set in three volumes and five 

 supplements, together with a manuscript index consummated 

 by the former owner, the eminent late Dr. Staudinger; Etudes 

 d Entomologie ', 18 76- 190 2, and Etudes de Ldpidopterologie, 1904- 

 191 1, by Charles Oberthiir; Entomologie ou Histoire Naturelle 

 des Insectes, 1789-1808, by M. Olivier; a complete set of 

 Palceontographia Italia, sixteen volumes; The Birds of Tunisia 

 by J. I. S. Whitaker. The acknowledgment and appreciation 

 of the Library and its many patrons are again extended to 

 the donor. The Library is also indebted to many other 

 individuals and institutions for interesting and important gifts. 

 J. Pierpont Morgan has presented a manuscript copy of 

 Descriptions of New Species of Mauritian Fishes written by 

 Richard Bliss, Jr., in 1875; this work is of special interest 

 since it serves in part as letter press for the volumes of 

 unpublished drawings which were received from the same 

 donor in 1905. Cleveland H. Dodge has continued his interest 

 by supplying the publications of The Carnegie Institution. 



Library Extension. — The use of our Library by sister 

 institutions and by scientists living at a distance is of special 

 moment at the present time. Through inter-library loans our
