[N. S. Vol. XXIV. No. 615. 



has been given leave of absence for the coming 

 year. 



Dr. Philip P. Calvert, of the department 

 of zoology. University of Pennsylvania, and 

 Mrs. Calvert have just returned from a six 

 weeks' tour in Mexico, where they collected 

 information on the distribution of the Odo- 

 nata on the northern part of the central 

 plateau. These data will be incorporated in 

 Dr. Calvert's section on the Odonata, now 

 nearly finished, in the Biologia Centrali- 

 Americana, edited by Mr. F. D. Godman, 

 F.E.S. As members of the International 

 Geological Congress, Dr. and Mrs. Calvert 

 participated in the sessions of that body, at 

 Mexico City, in September last. 



Dr. W. B. Huff has resumed his work as 

 head of the department of physics at Bryn 

 Mawr College after a year spent at the Caven- 

 dish Laboratory, Cambridge. 



Dr. 0. Tetens, of the Samoa Observatory, 

 has been appointed assistant in the Kiel Ob- 

 servatory. 



Professor Neisser, of Breslau, expects to 

 return next month to Java, to continue the 

 experiments on syphilis. 



Dr. John A. Brashear, of Pittsburg, will 

 give the address at Lehigh University on 

 Pounder's Day, to be celebrated on October 11. 



Professor Charles Baskerville, of the de- 

 partment of chemistry of the College of the 

 City of New York, will give a course of six 

 lectures on ' The Elements ' in the Brooklyn 

 Institute of Arts and Sciences every Tuesday 

 evening from October 16 to November 27. 



Professor A. E. Outerbridge, Jr., opened 

 the meetings of the section of mining and 

 metallurgy of the Franklin Institute, Phila- 

 delphia, on October 4, with a paper entitled 

 *■ Recent Progress in Metallurgy.' 



Dr. Andreas Hogyes, professor of pathology 

 at Buda Pesth and founder of the Pasteur 

 Institute in that city, has died at the age of 

 sixty years. 



The Chicago Academy of Sciences received 

 $100,000 under the will of W. Moses Willner. 



Under the name of Georg und Franziska 

 Speyer-Haus, there has been established at 



Frankfort-on-Main a chemico-therapeutic in- 

 stitute, which has been placed under the direc- 

 tion of Dr. Paul Ehrlich. 



We learn from The British Medical Journal 

 that an institution bearing the name of ' Labo- 

 ratoire Biologique du Radium ' has been at 

 work in Paris since July 1 under the direction 

 of Dr. Louis Wickham, surgeon to St. Lazare. 

 It is intended for the study of radium and its 

 applications to medicine. The institution, 

 thanks to the munificence of a wealthy manu- 

 facturing chemist, M. Armet de Lisle, is 

 equipped on a lavish scale. It comprises a 

 physical laboratory; a chemical laboratory; a 

 laboratory of experimental medicine, pathol- 

 ogy and bacteriology, and a clinical depart- 

 ment, partly for gratuitous, partly for paying 

 patients. Already, it is said, some interesting 

 therapeutic results have been obtained. 



A plea for , the preservation of .natural 

 scenes and objects in Germany was put for- 

 ward, says Nature, two years ago by Professor 

 H. Conwentz, director of the "West Prussian 

 Provincial Museum at Danzig, in a work on 

 ' Naturdenkmaler.' By Naturdenkmaler is 

 meant the whole natural landscape, with its 

 various soil formations, its water courses and 

 lakes, its special plant and animal communi- 

 ties, as well as single rare species and indi- 

 viduals of the original flora and fauna. Pro- 

 fessor Conwentz proposed that these results of 

 nature's handiwork in the different states of 

 the German empire should be placed on record 

 so as to make them known, and that provision 

 should be made for their protection. The 

 Prussian minister of instruction has just con- 

 sented to the establishment of a central office 

 for this purpose. For the present the office 

 will be at Danzig, and will be under the direc- 

 tion of Professor Conwentz. 



On account of strikes and other delays, 

 caused by the ventilation contracts, the com- 

 pletion of the new chemical laboratory of the 

 College of the City of New York has been 

 delayed. It is hoped to open the laboratory 

 formally some time in the winter. 



At the Harvard Collega Observt.tory a tele- 

 gram has been received from Profesf.or W. W.
