SCIENTIFIC JOURNALS AND ARTICLES. 



The American Naturalist for December 

 completes the thirty-fifth volume of this 

 journal and contains the index for the year. 

 The first article, by T. H. Morgan, is a dis- 

 cussion of ' Regeneration in the Egg, Em- 

 bryo and Adult,' including the use of the term 

 'polarity' in organic beings and inorganic 

 substances. The writer considers that the re- 

 organization of living beings is an entirely 

 diilerent phenomenon from that of inorganic 

 substances and one of the peculiar properties 

 of what we call living matter. C. M.- Child 

 tells of ' The Habits and Natural History of 

 Stichostemma,' a small fresh-water uemertean, 

 and W. M. Wheeler contributes another of 

 his important papers on the history of ants 

 under the title of ' An Extraordinary Ant- 

 Guest,' this being a phorid larva which fastens 

 itself to the neck of the larvas of a large 

 ponerine ant and feeds with its host on food 

 prepared by the workers. Herbert W. Rand 

 gives an extended abstract of ' Friedenthal's 

 Experimental Proof of Blood Relationship ' ; 

 this is found in the fact that the blood serum 

 of vertebrates undeniably related to one an- 

 other has no injurious effect on the corpuscles 

 of the different species, while it dissolves 

 those of unrelated species. Similarly the 

 transfusion of blood of species of one family 

 is harmless, while blood transfusion among 

 species of different species is harmful and may 

 cause death. The number contains the 

 ' Quarterly Record of Gifts, Appointments, 

 Resignations and Deaths ' ; Mr. Carnegie still 

 continues prominent in the founding of libra- 

 ries. 



The Popular Science Monthly for January 

 commences the sixtieth volume, and opens 

 with a description of ' The Minnesota Sea- 

 side Station' by Conway MacMillan. The 

 station is on the Straits of Fuca in a favorable 

 locality for varied research. The problems of 

 'Antarctic Exploration' are considered by 

 J. W. Gregory who notes the objects of the 

 four expeditions now on the sea, and Francis 

 Galton discusses ' The Possible Improvement 

 of the Human Breed under existing Condi- 

 tions of Law and Sentiment,' concluding that 



this is not only desirable but possible. Charles 

 V. Chapin writes of ' The End of the Filth 

 Theory of Disease,' but adds that we should 

 not become too closely wedded to the germ 

 theory which has replaced it. ' Recent 

 Eclipses of the Sun ' are described by Solon I. 

 Bailey, Edward S. Holden contributes a sketch 

 of ' Friar Roger Bacon,' and W. H. Dall 

 briefly reviews ' Lamarck, the Founder of Evo- 

 lution,' a biography by A. S. Packard. The 

 final article is on 'Comet's Tails, the Corona 

 and Aurora Borealis ' by John Cox, being a 

 detailed review of Arrhenius' theory concern- 

 ing them. 



The Plant Woi-ld for November contains 

 the ' Rooting of Oxalis Leaves ' by John L. 

 Shelton, ' The Blooming of Twining Honey- 

 suckles ' by Byron D. Halsted, ' Fairy Rings ' 

 by E. M. Williams, ' You Will Have to Hurry ' 

 by Aven Nelson, and ' Field Notes of a Mid- 

 sununer Tramp' by Charles C. Pitt. In 

 ' The Families of Flowering Plants ' Charles 

 L. Pollard treats of the Order Parietales. 



Popular Astronomy for January gives an 

 account of observations on the recent Leonids, 

 and an article by William H. Pickering upon 

 the 'Period of Revolution of the Leonids.' R. 

 G. Aitken, of the Lick Observatory, con- 

 tributes an article entitled 'The Sources of 

 Standard Time in the United States.' Shorter 

 articles are 'An Asteroid Orbit of Great 

 Eccentricity,' by E. C. Pickering; 'Eclipse Aid 

 to Chronology,' by the Rev. Q. A. Wheat ; ' The 

 Period of Algol,' 'Transformation of the Dif- 

 ferentials of Area and Volume,' by Asaph 

 Hall; 'Motion in the Faint Nebula surround- 

 ing Nova Persei,' by C. D. Perrine, and a 

 continuation of Dr. Wilson's ' Light Curve of 

 the New Star in Perseus.' 



Beginning with the new year The Forester, 

 the official organ of the American Forestry 

 Association and National Irrigation, the organ 

 of the National Irrigation Association, will 

 be combined and published under the name 

 of Forestry and Irrigation. 



Dr. George B. Shattuck, of the Johns Hop- 

 kins University, has lately been elected on the 

 Board of CollaboratOTS of the Annales de Geo- 

 graphie to take the place of Professor Wm. M.
