172 TRANS. OF THE ACAD. OF SCIENCE. 



some friends of our Academy, it will probably be made possible soon to 

 commence the publication of a fifth number of our Transactions. 



The Smithsonian Institution has continued to act as agent for the trans- 

 mission of our foreign exchanges, with but trifling expense to us. 



Our last, or fourth number, published in October, 1800, was sent to 

 them in May last, and is now, it is presumed, in the hands of the individ- 

 uals and societies abroad to whom it was directed. 



The total number of our home list is now sixty-nine, and of our foreign 

 list one hundred and sixty, nine of which have been added within the last 

 year ; and from several societies, and among others the Royal Society of 

 London, and the Geological Society of France, we have now for the first 

 time received their proceedings in exchange for ours. 



Our library has increased principally through these exchanges, having 

 received from this source an addition of 26(3 volumes, numbers or pam- 

 phlets. Different Congressional publications have been presented by the 

 Hon. Trusten Polk and the Hon. Frank P. Blair. Prof. E. W. Hilgard, 

 of Mississippi, Prof. A. Winchell, of Michigan, Prof. Guyot, Dr. Pollak, 

 and Dr. Engelmann, donated several valuable works to our library, and a 

 most important acquisition was the great work of Goldfuss on Petrefac- 

 tions, which the Academy bought from our member, Mr. C. Witter, on 

 easy terms. 



The additions to our Museum consisted in donations by members and 

 correspondents in the following departments: 



Comparative Anatomy. — Skulls of some rare Texan quadrupeds, by Dr. 

 B. F. Shumard. Skulls of Missouri animals, by Mr. I. T. Irwin, of Ra- 

 venna, Mo. 



Zoology. — E°:gs of Birds, by the same gentleman ; specimens of Reptiles 

 and Insects, by Drs. Pope, Wislizenus, and Shumard. 



Botany. — A large series of Algas, Fungi and Lichens, by Dr. Theo. C. 

 Hilgard ; Fruits by Dr. Pope. 



Mineralogy. — Specimens presented by Dr. Hilgard, Dr. Leigh, Dr. Shu- 

 mard, and Dr. A. Koch. From the latter we obtained a suite of the gold- 

 bearing rocks of Southwestern Missouri. 



Geology. — Fossils by Mr. Irwin, Mr. G. C. Broadhead, and General 

 Harney. 



It is proper to state here, that our former President, Dr. B. F. Shumard, 

 has, since his return from Texas, resumed the arduous duties of arranging 

 part of our collection, commenced at an earlier period by Dr. H. Prout, 

 and has thus greatly enhanced the value and the favorable appearance of 

 our Museum, while our Library was kept in complete order by Dr. G. H. 

 E. Baumgarten. While the former gentleman will henceforth, it is ex- 

 pected, devote his leisure to the Academy as a permanent citizen of our 

 town, the latter, who had just begun to study and arrange our herpetolo- 

 gical collection, has sought a wider field of usefulness, in the naval ser- 

 vice of the United States, where, it is hoped, he will not forget our insti- 

 tution. 



The following papers were read during the past year, most of them 

 intended for publication : 



From Prof. G. C. Swallow — On New Fossils of the Carboniferous and 

 Devonian Formation. 



Dr. B. F. Shumard — Cretaceous Fossils of Texas ; on the Geology of 

 Texas in gpneral ; on the Geology of Cape Girardeau County, Mo. 



Dr. A. Wislizenus — On Delltnann's Apparatus to measure Atmospheri- 

 cal Electricity, and his own Observations with this instrument ; on the 

 Army Worm, Bombyx graminis. 



Dr. H. Behr, of Sin Francisco, Cal. — On the Geographical Distribu- 

 tion of the Lppidoptera.

 and Transformation of the lowest vegetations of Fungi, Algae and Mosses.
