 No. 22, U. S. National Museum (guide to the Flora of Washington and vicin-

Oaulinites and Zamiostrobus. 



(Science, iii (No, 65, May 2, 1884), pp. 532^33.) 



Reply to a letter by Mr. Joseph F. James, in a previous number of Science, 

 criticising Mr. Lesquereux's figures of these fossil plants in his " Tertiary 

 Flora." 



The claims of political science. 



(Science, iii (No. 72, June 20, 18c!4), p. 748.) 



A brief note contrasting the treatment of political phenomena by scientific 

 men with that of other departments of natural phenomena, and maintaining 

 their essential homogeneity. 



The Upper Missouri River system. (Illustrated.) 



(Popular Science Monthly, xxv(No. 149, Sept., 1884), pp. 594-605.) 

 A description of the process by which the Upper Missouri and Yellowstone 

 Rivers excavate and transform their valleys, based upon personal olierva- 

 tiona chiefly made while descending the Missouri in an open boat, from Fort 

 Benton to Bismarck, in August and September, 188.*?. 



Irrigation in the Upper Missouri and Yellowstone Vallefrs. 



(Science, iv (No. 82, Aug. 29, 1884), pp. 166-168.) 



In this article the practicability and importance of irrigating the valleys of 

 these rivers is pointed out, and the advantage of making it a national enter- 

 prise to be conducted by the Government is considered.

Mind as a social factor. 



(Mind (London), ix, October, 1884, pp. 563-573.) 



This paper was read before the Anthropological Society of Washington, 

 February 19, 1884, as the vice-presidential address for the Sociological Sec- 

 tion. It was also read before the Metaphysical Club of Johns Hopkins Uni- 

 versity, April 22, 1884. It is an attempt to show that psychic phenomena, as 

 produced by beings with a highly-developed brain, have constituted a class 

 so far superior to all other forms of activity, that they must be treated by the 

 sociologist as distinct and not regarded as identical with the physical forces 

 of inanimate nature, as is practically done in the current laisnez /aire phi- 

 losophy. 



The fossil flora of the globe. 



(Botanical Gazette, iv, October and November, 1884, pp. 169-174.) 

 An abstract of three papers on this subject read September 8, 1884, before 

 the Biological Section of the American Association for the Advancement of 

 Science at Philadelphia. The subject is treated from the historical, geo- 

 logical, and botanical standpoints, and a tabular exhibit of the numerical 

 status of vegetable paleontology is appended.
