SCIENTIFIC JOURNALS AND ARTICLES. 



American Chemical Journal, February : ' On 

 the Constitution of the Salts of Imido-Ethers 

 and other Carbimide Derivatives,' by Julius 

 Stieglitz. ' On the Hydrochlorides of Carbo- 

 phenylimid Derivatives,' by H. N. McCoy. 

 ' On the Solubility of Argentic Bromide and 

 Chloride in Solutions of SodicThiosulphate,' by 

 T. W. Richards and H. B. Faber. From a study 

 of the solubility and effect upon the freezing 

 points of solutions caused by these salts certain 

 conclusions have been drawn as to the probable 

 nature of the substances present in solution. 

 'Note on the Spectra of Hydrogen,' by T. W. 

 Bichards. The author considers the presence 

 of the red spectrum to be due to a breakiug- 

 down of water vapor forming atomic hydrogen, 

 which gives the red spectrum. If the gas is 

 perfectly dry the white spectrum alone is ob- 

 tained. J. E. Gilpin. 



The first number of Bird Lore, edited by 

 Mr. F. M. Chapman, and devoted to popular 

 ornithology, has just appeared. As the official 

 •organ of the Audubon Society, and in appeal- 

 ing to young readers as well as old. Bird Lore 

 ■essays to cover a new field. The frontispiece 

 is a view of John Burroughs at ' Slab Sides,' 

 and the first article, ' In Warbler Time,' is from 

 his pen. There are two articles illustrated by 

 photographs from life, by Dr. T. S. Roberts 

 and H. W. Menke ; Miss Isabel Eaton has a 

 department for teachers and students, and Miss 

 Florence A. Merriam one for young observers ; 

 Notes, Reviews and Editorials follow ; while the 

 Audubon Department, edited by Mrs. Mabel 

 Osgood Wright, concludes the number. 



We have received the first number of The School 

 World, published in Great Britain, by Messrs. 

 Macmillan & Co., and addressed especially to 



teachers in the secondary schools. The first 

 number presents an interesting table of con- 

 tents including articles ou ' The Teaching of Al- 

 gebra,' by Professor G. B. Mathews, F.R.S.; 

 ' Physical Observations of Brain Conditions of 

 Boys and Girls in Schools,' by Dr. Francis 

 Warner; 'Bimanual Training in Schools,' by 

 Mr. H. Bloomfield Barry ; ' Elementary Ex- 

 perimental Science,' by Professor R. A. Greg- 

 ory and Mr. A. T. Simmons ; and ' Current 

 Geographical Topics,' by Dr. A. J. Herbertson. 



The Annual Report of the Director of the 

 Field Columbian Museum for 1897-98 notes 

 good progress, particularly in the Departments 

 of Anthropology, Geology and Botany. Two 

 of Mr. Akeley's fine groups have been added to 

 the exhibition series, one of the Oryx and one 

 of Waller's Gazelle, the latter very striking from 

 the pose of the principal figure and from the 

 extreme length of neck and limbs obtained by 

 these animals. One of the plates in the report 

 shows the large model of the moon recently 

 noticed in Science. The Director notes that 

 special attention has been given to what he 

 aptly terms the ' highly important but uninter- 

 esting and endless labor ' of cataloguing, inven- 

 torying and labelling 



SOCIETIES AND ACADE3IIES. 

 THE BIOLOGICAL SOCIETY OF WASHINGTON. 



The sooth regular meeting of the Biological 

 Society of Washington was held January 14, 

 1899, President Frederick V. Coville in the 

 chair. Brief notes were presented by the fol- 

 lowing members : Ashmead, Bailey, Pollard, 

 Erwin F. Smith, Chesnut and Cook. Mr. Ash- 

 mead exhibited specimens of a very rare South 

 American wasp [Chirodamus), the type of which 

 was secured by Charles Darwin during the voy- 

 age of the ' Beagle.' The new specimens were 

 secured by the U. S. Fish Commission and be- 

 long to the National Museum. 



Mr. Vernon Bailey described a case of pro- 

 tective coloration in Ochotona, a coney native 

 to the mountains of California. One of the 

 broken pieces of the rocks among which the 

 animals live was shown in comparison with a 

 stuffed specimen. Mr. Chesnut submitted pho- 

 tographs and fruits of the California Laurel
