bourhood. Professor Riicker has followed up this discussion by a 

 paper on " The Relation between the Magnetic Permeability of Rocks 

 and Regional Magnetic Disturbances," read before the Royal Society. 

 The high estimate that has been formed of the value of this 

 Magnetic Survey is perhaps most easily appreciated from the very 

 large sums that the Government Grant Committee have recom- 

 mended should be contributed to aid in the completion of this work 

 of international importance. 



Professor Victor Meyer (I)avy Medal). 



Professor Victor Meyer, formerly the successor of "Wohler at 

 Gofctingen, and who now occupies the chair of Bunsen at Heidel- 

 berg, is eminent as an original worker and discoverer in almost every 

 branch of chemical science. His methods of determining the vapour 

 densities of substances have been of the greatest service to chemists, 

 not only as convenient and generally applicable modes of ascertain- 

 ing atomic and molecular weights, but also as serving to throw light 

 on the molecular constitution of elements and compounds under 

 varying conditions of temperature and pressure. A striking example 

 of the value of these methods is seen in their application by their 

 author to the study of the molecular dissociation of the element 

 iodine one of the most masterly investigations of recent years, and 

 which is universally recognised as of the very highest significance 

 and importance. Not less noteworthy are Victor Meyer's services to 

 organic chemistry. His work on the nitroso-bodies, and his brilliant 

 discovery of thiophene, the initial member of a class of substances 

 hitherto unknown, his subsequent synthetical formation of it, and 

 the remarkable series of researches on its derivatives, in part carried 

 out with the aid of his pupils, stamp him as an investigator of 

 exceptional power and distinction.
