Nicholson, Prof. H. A. On the Bearing of Certain Palaeontological 

 Facts on the Darwinian Theory of the Origin of Species, and on the 

 General Doctrine of Evolution. Trans. Vict. Inst. vol. ix. p. 307. 



After a preliminary consideration of the general doctrine of Evolu- 

 tion, the author examines the chief propositions laid down by Mr. 

 Darwin in his chapter on the " Imperfection of the Geological Record." 

 He next examines the succession of life in a series of conformable 

 deposits, with special reference to the presence or absence of a series of 

 graduated forms between the species which lived at the commencement 

 of any single fonnation and those which were in existence at its close. 

 The U. Silurian and Devonian deposits of N. America are selected as 

 affording a good field for this investigation ; and the bearings of this 

 question are especially examined as regards the Bracliiopoda of these 

 deposits. A number of general propositions are laid down as to the 

 questions discussed. H. A. jN^.
