an unrivalled critical faculty, he uncompromisingly 

 attacked the dogmatic statements of some of his fellow- 

 members, and himself contributed the following three 

 papers :— i. " The Views of Hume, Kant, and Whately 

 on the logical basis of the doctrine of the Immortality of

 Essays, as " Geological Reform," viii, p. 305). — This 

 paid the usual tributes to the memories of deceased 

 Fellows, including in this case Bouchers de Perthes and 

 M. A. Morlot, eminent workers on prehistoric man in 

 France and Switzerland, Principal Forbes and Sir David 

 Brewster. The address itself was on the subject of 

 " Geological Reform," and had reference to the time- 

 limits which Sir William Thomson (now Lord Kelvin), 

 from the physical standpoint, had imposed upon geology 

 in his work "On Geological Time" (Trans. Geol. Soc, 

 Glasgow, iii). While admitting the necessity for accept- 

 ing time-limits of the kind, Huxley put forward a caveat
