Homogeneous Group in to Variables,' by Dr. 

 L. E. Dickson ; ' A Second Locus Connected 

 with a Sj'stem of Coaxial Circles, ' by Professor 

 Thomas F. Holgate ; ' Reciprocal Transforma- 

 tions of Projective Coordinates and the 

 Theorem of Ceva and Menelaos,' by Professor 

 Arnold Emch ; 'Notes'; ' New Publications.' 

 The January number of the Bulletin contains a 

 report on the ' Theory of Projective Invariants : 

 The Chief Contributions of a Decade,' by Pro- 

 fessor H. S. White ; ' Reye's Geometric der 

 Lage,' by Professor Charlotte Angas Scott ; 

 'Burkhardt's Theory of Functions,' by Pro- 

 fessor Maxime B6cher ; ' Darboux's Orthogonal 

 Systems,' by Professor Edgar Odell Lovett ; 

 'The New Mathematical Encycloptedia,' by 

 Professor James Pierpont ; ' Errata' ; ' Notes' ; 

 'New Publications.' The February number of 

 the Bulletin contains an account of the Fifth 

 Annual Meeting of the Society, by the Secre- 

 tary ; ' The December Meeting of the Chicago 

 Section of the Society,' by Professor Thomas 



F. Holgate ; ' Report on Recent Progress in 

 the Theory of Groups of a Finite Order,' by 

 Dr. G. A. Miller ; ' Note on Burnside's Theory 

 of Groups,' by Dr. G. A. Miller ; ' On a Regu- 

 lar Configuration of Ten Line Pairs Conjugate 

 as to a Quadric,' by Professor F. Morley ;

 Brown, Edgar Odell Lovett, J. W. A. Young,

American Chemical Journal, March : ' On the 

 Rearrangement of Imido-Esters,' by H. L. 

 Wheeler and T. B. Johnson. ' On an Isomer 

 of Potassium Ferricyanide,' by J. Locke and 



G. H. Edwards. By treating potassium ferri- 

 cyanide with potassium chlorate and hydro- 

 chloric acid an isomer of this salt was obtained. 

 An isomeric silver salt was also prepared and 

 the reactions studied. In some cases the re- 

 actions of the isomers are so different that the 

 author does not hesitate to accept this substance, 

 which he calls potassium /3-ferri cyanide, as a 

 new form. ' Reaction of Orthodiazobenzoic 

 Acid with Sulphurous Acid and Copper Pow- 

 der,' by W. E. Henderson. Experiments were 

 carried out to test the statements so generally 

 found in text-books that sulphonic acids are 

 formed from the decomposition of diazo com- 

 pounds by sulphurous acid in the presence 



of copper powder. The results showed that, 

 under ordinary conditions, sulphonic acids 

 were not formed. ' Direct Nitration of the 

 ParaflBns,' by O. A. Worstall. The author 

 finds that the results as given in his earlier 

 papier on the action of nitric acid on the 

 paraffins hold for all the paraffins studied. 

 'Higher Primary Nitroparafflus,' by R. A. 

 Worstall. The author has continued the study 

 of the derivatives of the higher paraffins on the 

 line suggested by Victor Meyer in his study of 

 the lower members of the series. ' The Action 

 of Ethylic Oxalate on Camphor,' by J. B. and 

 A. Tingle. 'Liquid Acetylene Diiodide,' by 



E. H. Keiser. A second form of the three 

 theoretically possible ones has been obtained in 

 liquid form. 'A Simple Color Reaction for 

 Methyl Alcohol,' by S. P. Mulliken and H. 

 Scudder. The alcohol is converted into formic 

 aldelyde by plunging a hot copper wire into it. 

 Resorcin and sulphuric acid are then added and 

 a characteristic color reaction follows. ' Re- 

 actions for the Detection of the Nitrogroup,' by 

 S. P. Mulliken and E. R. Barker. The first 

 method depends on the reduction to hydroxy- 

 lamine and the test for this with silver nitrate, 

 and the second on the conversion into rosa- 

 niline. J.' Elliott Gilpin. 



The Osprey, for January, has for its first article 

 some interesting ' Notes on Eugenes fulgens ' by 



F. C. Willard, accompanied by a fine plate 

 showing four nests. Next comes descriptions 

 of the 'Nesting of the Alaska Bald Eagle,' by 

 George G. Cantwell, followed by descriptions 

 of the habits in captivity of Great Horned 

 Owls, Barn Owls and young Short-eared 

 Owls respectively, by M. A. Carriker, D. A. 

 Cohen and Ludwig Kumlien. ' A Visit to 

 Pelican Island, Indian River, Florida,' is de- 

 scribed by L. W. Brownall, and the ' Nesting 

 of the Black-and- White Warbler,' by J. Warren 

 Jacobs. Other brief articles, editorials, notes 

 and reviews complete the number. 



The leading article of the Journal of the Bos- 

 ton Society of Medical Sciences is a series of ' Ob- 

 servations upon the Elastic Tissue of Certain 

 Human Arteries,' by George B. Magrath. 

 Richard M. Pearce has a paper on ' Scarlet 

 Fever ; its Bacteriology, Gross and Minute
