tion of Dr. Norwood. Surveys are also continuing at present in North 

 Carolina under Dr. E. Emmons ; in Alabama, under Prof. M. Tuomey; in 

 Canada under Mr. Logan; and in Pennsylvania, under Prof. H. D. Rog- 

 ers. The report of this last elaborate survey will appear in two quarto 

 yolumes, with a large map, and among other points of special interest, 

 will contain a monograph of the coal plants of the United States by Mr. 

 Lesquereaux. The States of Missouri and Florida, are now the only ones 

 which have not yet authorized surveys. 



A geological reconnoissance of the Territory of Oregon, is now being 

 made under the direction of the General Land Office, by Dr. Evans. 



The obituary register for 1852, both in the United States and in Europe, 

 contains the names of many who have been distinguished in the annals of 

 science, and have been useful to their fellow-men. The American list 

 includes the names of Norton, Downing, James Rogers, Johnson, Overman 

 Woods Baker, Drake, Lassel, and others. We have also to record since 

 the commencement of 1853, the death of Prof. C. B. Adams, and the dis- 

 tinguished American astronomer and mathematician, Sears C. Walker. 



Satisfactory information has also been obtained during the past year 

 respecting the fate of Jaques Compagnon, the long lost African traveller, 

 and of Dr. Ludwig Leichardt, the missing explorer of Central Australia. 

 The first named died in captivity in the interior of Africa, among the tribe 

 of Kommenis. He departed from Senegal in 1758 and was last heard from 

 in 1760. Dr. Leichardt left Sidney a few years since for the purpose of 

 exploring the interior of Australia, the extent of Sturt's desert, and the 

 character of the western and north-western coast, and to observe the gradual 

 change in vegetation and animal life, from one side of the continent to the 

 other. This expedition was expected to occupy two and half years in 

 reaching Swan River. One letter only was received from him by a friend 

 in Sidney, when he was eleven days out, closing with these words : " See- 

 ing how much I have been favored in my present progress, I am full of 

 hope, that our Almighty Protector will allow me to bring my darling 

 scheme to a successful termination." Since then his fate has remained a 

 mystery, until within a recent period it has been definitely ascertained 

 that he was killed by the natives, after haying penetrated 1200 miles into 

 the interior of Australia.
