Professor Daubree was a prolific writer, his best known work 

 being a large treatise published in 1879 under the title of " Etudes 

 synthetiques de Geologie Experimentale," wherein he collected the 

 results of his experimental work which had been recorded in the 

 A nnales des Mines s^nd other scientific journals. The year after this 

 publication he received from the Geological Society of London the 

 Wollaston Medal, appropriately awarded during the presidency of 

 Dr. Sorby, whose work as an experimental geologist had run to some 

 extent in a parallel direction. Another of Daubree's important works 

 was his three-volume treatise entitled " Eaux Souterraines," which 

 appeared in 1887. 



Professor Daubree was formerly a frequent visitor to England, 

 where he was endeared to a large circle of scientific friends, many of 

 whom are now passed away. Twenty years ago he delivered an 

 address on his favourite topic at the Science Conferences held in 

 connection with the Loan Collection of Apparatus at South 

 Kensington. A man naturally of simple habits and warm affections, 

 unaffectedly modest, yet saturated with scientific enthusiasm, Daubree 

 lived and died beloved as a friend by those who knew him, and 

 admired by all as an original investigator of the first rank.

WE deeply regret the premature death of this investigator, who was 

 accidentally drowned while bathing at Dover. He had received 

 his first appointment last year as lecturer on biology in Charing Cross 

 Hospital. Dr. Pollard was a Scholar of Christ Church, Oxford, 

 whence he obtained a research scholarship on taking his degree. He 

 proceeded to study in the Anatomical Institute of the University of 

 Freiburg, and next, in 1892, occupied the Oxford University table in
