Section B. Chemistry. 



Professor Sydney Young, D.Sc. F.R.S., is the third son of 

 Mr. Edward Young, of Liverpool, and was born on Decem- 

 ber 29 at Farnworth. near Widnes. He entered Owens 

 College in 1S76, becoming an .-Vssociato of the College in i.SSo, 

 and in the same year was awarded the Scholarship in Chemis- 

 try in the B.Sc. final of London L'niversity. He proceeded to 

 his D.Sc. degree three years later. At Owens College he

conducted an investigation on " Alcoholic Thiorides," and at the 

 University of Strasburg. where he spent a year in Professor 

 Fittig's laboraton,', he carried out researches on " Ethyl- 

 valero-lactone " and other compounds. In 18S2 Dr. Young 

 was appointed Lecturer and Demonstrator of Chemistry in 

 University College, Bristol, and during the following five 

 years he was engaged in original work, chiefly in physical 

 chemistry, jointly with Professor Ramsay. On Professor 

 Ramsay's migration to London and occupation of the Pro- 

 fessorship of Chemistry at Gower Street, Dr. Young was 

 elected to the Chair of Chemistry at University College, 

 Bristol. He was elected a Fellow of the Royal Society in 

 1893, and is a Member of the Council of the London Physical 

 and Chemical Societies. He was appointed last October to 

 the Chair of Chemistry in Trinity College, Dublin, in succes- 

 sion to Professor Emerson Reynolds ; and this year, as an old 

 Associate of Owens College, Manchester, received the B.Sc. 

 degree of the new Victoria University. His important work 

 on " Fractional Distillation " was published last October. 



Professor Sydney Young's Presidential address to the 

 Chemical Section was a review of the state of knowledge of 

 the chemical properties of mixtures, beginning with a summary 

 of Kopp's work during last century on the molecular volumes 

 and boiling points of chemical tompouuds and eudiug with the 

 researches of Professor Kuenen. Professor \oung defined the 

 investigations of the behaviour of liquids when mixed logctluT 

 as referring to ((() their miscibility, infinite, partial, or inajipre- 

 ciable; (/i) the relative volumes of the mixture and its com- 

 ponents; and (V) the heat evolved or absorbed ; .lud he uiMit 

 on to outline the modes of investigation appliiil to these 

 phenomena.

 gist on the Geological Survey of England and Wales ; born 

 London, April 20, 1852. F.ducated at Eton and St. John's 

 College, Cambridge.

AUBREY STRAHAN. 



Mr. Aubrey Strahan's address to the Geological Section 

 was an attempt to outline the Earth Movements and Earth 

 Sculpture, gradual or cataclysmic, which resulted in the 

 geological formations and the external landscape of the 

 British Isles as now known. With such a history, he con- 

 cluded, and with the knowledge that mountain ranges had 

 been built in other parts of the world l)y upheavals of almost 

 recent date, thev had more cause to wonder that the internal 

 forces of the globe had left this region for so long, than reason 

 for believing that such phenomena had ceased. Slow changes 

 of level were still occurring; and these might be the outward 

 manifestation of more complicated movements in progress at 

 a depth. The President offered a conjecture as to what 

 appearance the globe would have presented had it not been 

 enveloped with an atmosphere and covered for the most part 

 with water. If these had not existed, the old scars, caused by 

 the belts of crushing and buckling, would have remained, 

 unsoftened by denudation, uncovered by sedimentation. The 

 Earth would then have appeared to the inhabitant of another
