For the series here described, the American 

 Museum and Mr. Jesup, the Maecenas of 

 American ethnology, deserve hearty praise. It 

 is now in order for others of our great museums 

 to wake up and let us hear from them.

SCIENTIFIC JOURNALS AND ARTICLES. 

 The Bulletin of the American Geographical So- 

 ciety for October 31, 1900, contains an excellent 

 picture of the late president of the Society, the 

 Hon. Charles P. Daly, which forms the frontis- 

 piece of this number. Judge Daly was the 

 honored president of this, the oldest Geograph- 

 ical Society in America, and the portrait painted 

 by Harper Pennington forms a fitting memorial 

 of the thirty-five years of active service to the 

 Society. The number contains a larger series 

 than usual of what might be called new articles. 

 First among these is an article upon the ' Ethnol- 

 ogy of Madagascar,' by the Hon. W. H. Hunt, of 

 Tamatave, dealing largely with the tribal names 

 and the early immigrations, showing that there 

 must have been a series of migrations from an 

 Asiatic source. The second section of the paper 

 discusses the early maps of the island, and then 

 takes up the geography and cartography of 

 Madagasgcar as developed between 1897 and 

 1899. This new work is due largely to the 

 initiative of General Gallieni. This is followed 

 by an article descriptive of the ' Heaths and 

 Hollows of Holland,' by Dr. "W. E. Griffiths, a 



bright and entertaining tale of this ' water- 

 logged ' country and its people. ' Korea's Geo- 

 graphical Significance ' is discussed by H. B. 

 Hulbert, of Seoul, in a scholarly paper showing 

 the relations brought about by this stepping 

 stone from Asia to Japan, giving the results 

 produced as a link between two widely separated 

 branches of the Turanian stock ; and then again 

 when serving as a barrier between active Japan 

 and ambitious Russia. Mr. Henry Gannett, of 

 Washington, gives a careful resumS of the recent 

 census of Porto Eico. This new addition to 

 our domain has a population of 963,243, thus 

 showing a very dense population of its 3,600 

 square miles. An outline sketch of the geogra- 

 phy of British Honduras is given by Hon. W. 

 L. Avery, of Belize. This is followed by an 

 account of a trip through the silk and tea dis- 

 tricts of Kiangnan and Chepiang, by E. S. 

 Fischer. The portion of the Bulletin devoted 

 to notes in this number is particularly full, 

 and covers the departments of physiography, 

 map notices, climatology, geographical edu 

 cation and the general geographical record. 

 Cosmos Mindeleff gives a full account of the use 

 and manufacture of geographical relief maps, 

 and M. Henri Froideveaux gives a sketch ot 

 geography at the Paris Exposition. At the end 

 of the number there is a picture of the new 

 home of the Society, Manhattan Square on 81st 

 street, giving a view of the front of the building 

 and plans of the grounds and library floors. 

 The enterprise of the Council in constructing 

 this building as a repository for its fine library 

 and a commodious place for the intercourse of 

 the Fellows of the Society, is deserving of the 

 highest praise. 



The Plant World for October opens with 

 ' Notes for the Beginner in the Study of Mosses, ' 

 by F. H. Knowlton, the first of a series on the 

 lower plants. A. S. Hitchcock describes ' Col 

 lecting Sets of Plants for Exchange'; E. J. 

 Hill has ' An Observation on the Water-Shield 

 (Brasenia peltata), dealing with the dissemiua 

 tion of its seed ; Charles Newton Gould de- 

 scribes the ' Radiate Structure of the Wild 

 Gourd' {Curcuhita foetidissima), and Joseph 

 Crawfoi'd has some ' Notes on Ophioglossum. ' 

 In the supplement devoted to ' The Families of 

 Flowering Plants,' Charles Louis Pollard deals
