SCIENCE. 



[Vol. I., No. 11. 



The proceedings of the several sectional meetings 

 contain discussions on numerous topics: such as, 

 Egyptian climate, Abbate and Mahmoud Beys con- 

 tending that there were no signs of its having changed 

 within the past twelve centuries; the formation of 

 coral-reefs by other means than subsidence, as sug- 

 gested by Semper and Murray, and here maintained 

 by Rein and Fischer; tlie definition and limitation 

 of scientlfle geography to the study of the form of the 

 earth's surface, including the manifestations and re- 

 ciprocal relations of organic forms, with the aid, where 

 necessary, of other sciences, its distinguishing charac- 

 teristics being the study of position and distribution; 

 the advisability of representing mountain relief and 

 oceanic depression in school-atlases by contour-lines 

 and sliades of color rather than by hachures; the 

 exploration of the Mediterranean by Magnaghi and 

 Giglioli, on the ' Washington,' in 1881, their re- 

 sults about Sicily and Sardinia showing a greater 

 variety in the bottom fauna than had been previously 

 found, and an almost uniform temperature of 13.5° to 

 13° C. at all depths from 800 to 3,634 metres. Three 

 maps are published in this volume. One shows the 

 position of meridian arcs, measured up to 1865, for 

 geodetic purposes (the arc in southern Africa seems 

 accidentally omitted). Another gives the primary 

 triangulation of Europe, showing a wonderful network 

 of accurately determined lines. This, taken with the 

 maps given in our coast-survey reports, and the map 

 of Indian triangulation, reproduced in Markham's 

 ' Indian surveys,' will show about all that has yet 

 been accomplished in this direction. A third plate 

 shows the route of the ' Washington ' in 1881. A sec- 

 ond volume of acts and communications is promised, 

 in which more extended and valuable reports of 

 scientific papers will be published. 



— American entomologists will regret to learn the 

 sudden death of Prof. P. C. Zeller, by heart-disease, 

 at his residence in Griinhof, near Stettin, Prussia, 

 on the 27th of March. He has been known for 

 many decades for his excellent systematic work 

 on Lepidoptera, especially the lower groups, and of 

 late years has contributed memoirs of importance 

 on American forms. He died at the age of seventy- 

 five, and was actively engaged in his favorite studies 

 to the last.
