corouse. There follow a memoir on mirages by 

 Monge (1797) and an account by Scoresby 

 (1820) of some remarkable atmospheric reflec- 

 tions and refractions in the Greenland Sea; 

 the earliest discussion of twilight by Alhazen 

 (about 1000) and the first good account of the 

 anti-twilight arch by Mairan (1753). The 

 volume contains several illustrations, which 

 like some of the text are in facsimile, and is 

 enriched with the usual historical and ex- 

 planatory notes. Dr. Hellmann's work is al- 

 ways so exact that it is a surprise to find 

 slight typographical errors on page 83 in the 

 reprint of Scoresby's paper. Like its prede- 

 cessors, the present volume is published with 

 the aid of the German Meteorological Society, 

 which has fixed the price at 11 marks ($2.75), 

 and although it is not on sale in this coun- 

 try, two or three copies may be purchased 

 at the above price from the Blue Hill Observa- 

 tory, Hyde Park, Mass. Before closing my 

 reviews of these reprints of rare papers, it 

 should be mentioned that already several of 

 the preceding thirteen numbers are out of 

 print, which shows that Dr. Hellmann's enter- 

 prise has been quickly appreciated by librari- 

 ans and private collectors of historic docu- 

 ments.

SCIENTIFIC JOURNALS AND ARTICLES. 



Bird Lore for July-August opens with an 

 entertaining article 'Concerning the Bad Re- 

 pute of "WTiiskey John' by Fannie Hardy Eck- 

 storm, and this is followed by some well illus- 

 trated 'Nighthawk Notes' by George H. Sel- 

 leck. Ernest Crosby contributes a poem on 

 'The Veery's Note' and John Hutchins de- 

 scribes in some detail 'The Nesting of the 

 Yellow-Throated Vireo.' Edith M. Thomas 

 commemorates in verse the destructiveness of 

 'The Sapsucker,' and the instalment of 'Plow 

 to Name the Birds' is devoted to the vireos, 

 warblers and pipits. The reviews and reports 

 of societies are of interest, as is also the edi- 

 torial on nomenclature. 



The Plant World for July contains 'Through 

 Desert and Mountain in Southern California' 

 by S. B. Parish, 'The Protection of Native 



Plants' by Idelette Carpenter and 'Plants 

 used for Cuban Confectionery ' by Charles 

 Louis Pollard. In the supplement devoted to 

 the Pamilies of Flowering Plants Mr. Pollard 

 continues the descriptions of the families of 

 the Polemoniales. 



IVie Museums Journal of Great Britain be- 

 gins its second year with the July number. 

 The Report of the Council of the Museums 

 Association states that the publication of the 

 Journal has been in every way a success and 

 that it will soon begin the publication of a 

 Directory of Museums as a Supplement. The 

 first instalment will probably be in the August 

 number. The leading article is the address of 

 the president of the Museums Association, 

 Mr. W. E. B. Priestly. There is a description 

 of a museum microscope which has just been 

 placed on the market by Messrs. W. Watson 

 and Sons. As now arranged this instrument 

 is limited to 12 slides, but we see no reason 

 why it could not be so modified as to take 

 slides placed on an endless belt after the 

 method devised by Dr. J. M. Flint and used 

 in the Army Medical Museum. There is a 

 too brief account of the opening of the very 

 interesting War and Peace Museum at Lu- 

 cerne, designed to illustrate the history and 

 horrors of warfare with a view to aiding in 

 its abolishment. 



The American Naturalist for August con- 

 tains a description, in some detail, of 'The 

 Anatomy of a Double Calf by H. L. Osborn, 

 an account of 'The Metamorphosis of Sisyra' 

 by Maude H. Anthony, which contains as well 

 many details of the anatomy of the larva and 

 of wing variation in the adult. Henrietta F. 

 Thacher describes 'The Regeneration of the 

 Pharynx in Planaria maculata' and William 

 A. Hilton ' A Structural Feature connected 

 with the Mating of Diemyctylus viridescens,' 

 these being the small pits on the sides of the 

 neck. These are much larger in the male than 

 in the female and their secretion is thought 

 to attract the female and cause her to follow 

 the male after mating. C. R. Eastman gives 

 'Some Hitherto Unpublished Observations of 

 Orestes St. John on Palaeozoic Fishes' and S. 

 N. Rhoads presents some observations on 'The
