528 Obituary — Professor Edward Hull. 



chloride acts in conjunction with the gases of the atmosphere. The 

 evidence for all this is presumably given in Professor Wallace's 

 complete paper, but I do not know whether that has yet been 

 published. In the case of Mr. Dunn's pebbles, instead of a persistent 

 film there is regular alternation of wet and dry, so that the chemical 

 action, if any, must be considerably less than the mechanical ; mere 

 attrition appears to be excluded.

OBITTJAET. 



FRANCOIS CYRILLE GRAND'EURY. 

 Born March 9, 1839. Died July 22, 1917. 



Br the death of M. Grand' Eury palaeobotany loses one of its most 

 distinguished and energetic pioneers. As a mining engineer who 

 spent his life in coal-fields, lie had unrivalled opportunities for 

 observing Carboniferous plants in situ, and he always made the most 

 of every discovery which came under his notice. His special studies 

 enabled him to correlate various roots, stems, foliage, and fruits 

 which as isolated fossils had received separate names. He also made 

 many important observations bearing on the origin of coal. His 

 well-known memoir on the Carboniferous Flora of the Loire was 

 published by the Paris Academy of Sciences so long ago as 1876. 

 His great work on the Coal Basin of the Gard appeared in 1890. 

 Numerous other publications culminated in his Recherches geo- 

 botaniques, which were in course of issue at the time of his death.
