localization of the origins of these world shak- 

 ing earthquakes, beside indicating the sub- 

 oceanic sites of geological activity, positions 

 where the hydrographer may expect to flnd- 

 unusual depths. They have also shown routes 

 to be avoided by those who lay cables. 



Seismograms of unfelt movements throw light 

 upon what have up to recently been regarded as 

 unaccountable deflections in the photograms 

 from magnetographs, barographs, and other 

 instruments sensible to slight displacements. 

 They have also explained unusual rates in cer- 

 tain time-keepers. The most important scientific 

 result obtained is dependent upon observations 

 on the rate at which motion is propagated in 

 various directions through the world. Until 

 these observations had been made, our knowl- 

 edge respecting the interior of the earth, chiefly 

 related to its density and temperature, now we 

 know much respecting its rigidity.

Otto H. Tittman, assistant superintend- 

 ent of the U. S. Coast and Geodetic Survey, 

 has been promoted to the superintendency,

 Pritchett, to accept the presidency of the Mas- 

 sachusetts Institute of Technology. Mr. Titt- 

 man has been connected with the Survey since

 parative Zoology at Cambridge, Mass. 



SiE Joseph Hookee, the eminent English 

 botanist, has been elected a foreign associate 

 of the Paris Academy of Sciences. 



LoED LiSTEE has resigned his position on the 

 Senate of the University of London as repre- 

 sentative of King's College, and Dr. Thomas 

 Buzzard has been appointed in his place. 



Me. Eyelyn B. Baldwin has sailed for Eu- 

 rope to examine methods of polar exploration, 

 and to secure equipment for the proposed ex- 

 pedition under the auspicies of Mr. Ziegler. 



Peofessoe Gael Gegenbaue has received 



the Swammerdam medal of the Amsterdam 

 Society of Medical and Natural Science. 



Me. Leeoy Andeeson, who was this year 

 called from Cornell University to the Univer- 

 sity of California as instructor on dairy hus- 

 bandry, has been offered the position of chief 

 agriculturist in the Philippines. Mr. Law- 

 rence M. Jacobs, of the Treasury Department, 

 has been appointed statistician of the Taft 

 Philippine Commission. 



De. a. Donaldson Smith, after lecturing 

 before the Royal Geographical Society, has re- 

 turned from England to his home in Philadel- 

 phia. 



De. Eobeet T. Hill, of the U. S. Geological 

 Survey, non-resident lecturer to the University 

 of Michigan, is now delivering a series of lec- 

 tures at that University on ' The Industrial 

 Significance of the West Indies to the United 

 States.' 



An executive committee has undertaken to 

 erect a bust of the late Professor J. B. Carnoy 

 in the cytological laboratory established by Mm 

 in the University of Louvain. An honorary in- 

 ternational committee has been formed, includ- 

 ing in America Messrs. Agassiz, Eigenmann, 

 Macallum, McMurrich and Minot. 



It is proposed to found two memorials in 

 honor of the late Miss Mary Kingsley, one a 

 small hospital at Liverpool for the treatment of 

 tropical diseases and one a Society for the study 

 of the natives of West Africa. It is planned 

 "that the ' Mary Kingsley Society ' should em- 

 ploy a trained ethnologist, both to collect and 

 arrange in scientific form the material which is 

 thus already on record, and to institute and di- 

 rect research for further material of the same 

 sort ; and it is intended that the Society, after 

 the manner of the Royal Asiatic Society, should 

 periodically publish the results which it obtains 

 and should thus provide additional knowledge 

 by which European relations with West Africa 

 may be most safely and effectively directed, 

 with profit both to the natives and to the 

 Empire."
