even of a scientific character, being admitted during that time, 

 as the Museum is designed to advance science generally, and 

 in no way to afford either its Director or the curators of the dif- 

 ferent departments an opportunity of benefiting themselves. It 

 is a great pleasure for me as Director to be able to say that all 

 the officers of the Museum are now cooperating with me in that 

 spirit. It is, no doubt, to this devotion to the institution on the 

 part of so many able workers, that the Museum owes its unpar- 

 alleled and rapid growth. Moreover, the services of Messrs. 

 Theodore Lyman, Alex. Agassiz and T. G. Cary are given 

 gratuitously. 



The intended arrangement of the collection is not yet fully 

 made apparent, owing to want of room. It may, however, be 

 said that in preparing specimens for exhibition, the intention of 

 keeping the f'aunal collections distinct from the general system- 

 atic collection is constantly held in view, and that synoptical col- 

 lections are made besides, for the special use of students, not 

 to speak of the collections intended to illustrate the structure, 

 development and successive appearance upon earth of the dif- 

 ferent classes of the animal kingdom, which from their very 

 nature require to be put up separately. 



The zoological collection intended for the special use of stu- 

 dents, begun in 1861, has been extended, and in some parts 

 completed and labelled. A new gallery destined for a special 

 palasontological collection, also for the exclusive use of stu- 

 dents, has been cleared for this purpose. Elementary collec- 

 tions of typical specimens are also preparing for our normal 

 schools ; but I find it most difficult to make proper selections. 



The accessions to the Museum during the past year have been 

 very great and of surpassing importance. Foremost stands 

 Deyrolle's collection of Curculionidae, presented by Mrs. A. 

 Hemenway ; next the collection of Galls of Baron d'Osten-Sacken, 

 presented by him ; then the magnificent collection of Fossil 

 Plants of Mr. Lesquereux, especially remarkable for the exqui- 

 site selection of the specimens it contains, and that of Insects of 

 Texas, made by Mr. J. Boll, both of which have been bought 

 by the Museum. 



The fact that Dr. Hagen has brought to this country his un- 

 paralleled collection of Neuroptera, which is now deposited in 

 the Museum, is calculated to have the most beneficial influence
