534 General Notes. LJ une » 



— The views of Dr. Hahn, as to the presence of organic struc- 

 tures in meteorites,- have been refuted by Professor Carl Vogt, 

 who, in a memoir presented to the French Academy of Sciences, 

 affirms that Dr. Hahn has no foundation for his conclusions, and 

 that in no single case do the pretended organic structures present 

 the microscopic appearance of the organisms for which they have 

 been mistaken. — English Mechanic. 



— G. T. Wetterman, Director of the Museum Koninklijk Zo- 

 ologisch Genootschap, Amsterdam, Holland, writes that within a 

 short time the new aquarium buildings, recently erected in the 

 gardens, will be opened, not only for the recreation of the members 

 of the society but to audiences for the academical course of zo- 

 ology, as well as for laboratories for anatomical research. Director 

 Wetterman states that naturally all sorts of sea animals will be 

 needed for the work, and requests the addresses of aquaria in 

 America that will enter into a mutual exchange of marine ani- 

 mals or will dispose of them by sale. He expresses a wish to 

 have as much as possible of the American submarine fauna rep- 

 resented in their tanks. 



— James Geikie, LL. D., author of the " Great Ice Age," and 

 for twenty-one years a member of the Geological Survey of Great 

 Britain and Ireland, has recently received the appointment to the 

 Murchison Professorship of Mineralogy and Geology in the Uni- 

 versity of Edinburgh, made vacant by the appointment of his 

 brother, Professor Archibald Geikie, to the director-generalship 

 of the Geological Survey. He has resigned his position in the 

 survey and enters upon his duties in the University in May. 



— But two summer schools of science will apparently be 

 opened to students this coming season, one at Annisquam, Cape 

 Ann, Mass., under the charge of Professor A. Hyatt, curator of 

 the Boston Society of Natural History; the other is the summer 

 school of biology of the Peabody Academy of Science, Salem, 

 Mass. Both offer good facilities for study. 



— We are asked by Professor E. S. Morse to correct a mistake 

 on page 326 of the Naturalist in reference to the Japanese stu- 

 dents. Mr. Ijima and Mr. Iwakawa have never been abroad, 

 what they have acquired has been learned in Japan. Mr. Mit- 

 sukwri was a fellow at Johns Hopkins University and was a stu- 

 dent of Professor W. K. Brooks. 



— The Princeton College Exploring Expedition obtained a 

 skull of the Eocene mammal Achanodon insolens Cope, whose 

 position has been heretofore doubtful. It turns out to be a flesti- 

 eater of the family Arctocyonidce, and is the largest species known. 

 It was a formidable animal, as large as a brown bear, and is proD- 

 ably the ancestral type from which bears were derived. Messrs. 

 Scott and Osborne will publish a memoir on it in the Contribu- 

 tions of the Museum of Geology and Archaeology.— £ D. tofe-
