is to have charge of the specimens aud be ready at all times to give 

 botanical iuformation that may be required by the general public or by 

 the Smithsonian correspondents. Moreover, in return for the specimens 

 transferred to the Medical Museum the Institution receives from the 

 officers of the army all collections made in ethnology and in special 

 branches of natural history. 



PiTBLiCATiONS. — The publications of the Institution form an essential 

 part of its operations and constitute the principal basis of the great sys- 

 tem of Smithsonian international exchanges. As has been frequently 

 stated in previous reports, they are of three classes : the Contributions 

 to Knowledge, the Miscellaneous Collections, and the Annual Eeports. 

 The first consist of memoirs containing positive additions to science 

 resting on original research, and which are, principally, the result of 

 investigations to which the Institution has in. some way rendered assist- 

 ance. The Miscellaneous Collections are chiefly composed of. works 

 intended to facilitate the study of ethnology, natural history, and mete- 

 orology. They are designed to facilitate the progress of those who en- 

 gage in special studies, to which, in their leisure moments, their thoughts 

 may recur, and in connection with which, while contributing to their 

 own i)leasure, they may advance the cause of science. The Annual 

 Eeports, besides giving an account of the operations of the Institution, 

 furnish, in an ai^pendix, matter of importance to the meteorological 

 observer aud of interest to the general public. The Contributions and 

 Miscellaneous Collections are published at the expense of the Smithson 

 fund, wliiie the Eeports, with the exception of the illustrations, are 

 jirinted by the government.
