and a basement. These stories will be devoted to the hbrar}^, the 

 museum, and a large and convenient lecture-room. 



The business of the Institution would be much facilitated were this 

 part of the building completed. Since Congress has authorized the 

 establishment of a library and museum, it will be well to place all the 

 objects of interest to the public in the main building, and make this 

 exclusively the show part oi" the establishment, devoting the wings and 

 ranges, and rooms of the towers, to the business operations and other 

 purposes of the Institution. In the present condition of affairs there is 

 no part of the edifice to which the public has not access, and, conse- 

 quently, business has to be transacted amidst constant interruptions. 

 The loss of time and effective life to which all are exposed who occupy 

 a position of notoriety in the city of Washington, is truly lamentable ; 

 and where this is enhnnced by facility of access to gratify mere curi- 

 osity, the evil becomes scarcely endurable. Progress in business, under 

 such circumstances, can only be made by an encroachment on the 

 hours usually allotted to rest, and that, too, at the expense of wasted 

 energies and shortened days. 



Publications. — During the past year the following memoirs, described 

 in the previous reports, have been collected into volumes and distrib- 

 uted to public institutions in this country and abroad : 



1. Observations on Terrestrial Magnetism. 



2. Researches on Electrical Rheometry. 



3. Contributions to the Natural History of the fresh-water fishes of 



North America. 



4. First part of the Marine Algae of the coast of the United States. 



5. Plantae Wriohtianae Texano, Neo Mexicana, Part I.

6. Law of Deposit of the Flood Tide, its dynamical action and 



office. 



7. Description of ancient works in Ohio, 



8. Occullations visible in the United States during the year 1852. 



9. A Grammar and Dictionary of the Dakota language. 



The memoir last mentioned occupies an entire volume, the fourth of 

 the Smithsonian series of contributions. The other memoirs are con- 

 tained in the third volume of the same series. 



The remaining memoirs, described in the last report, are still in the 

 press, the printing of them having been delayed by the exhaustion 

 of the appropriation for the year, and by several necessary corrections. 

 A suflficient number of papers will, however, be printed in the course 

 of a few months, with the new appropriation, to complete the fifth volume 

 of Contributions; and if the means prove sufficient, we can readily 

 issue the sixth volume during the present year. 



The result of the plan of publication has fully realized the anticipa- 

 tions which were entertained regarding its usefulness. It supplies the 

 food it feeds upon. The appearance in the Contributions of a memoir 

 on any subject immediately directs attention to that subject, and induces 

 other laborers to engage in the same field of exploration. This is 

 particularly manifest in the interest awakened with regard to the
