 By the Rev. A. Sedgwick, F.R.S., G.S. &c. 



After a painful interruption of three years, I resumed my geological 

 work during the past summer, and revisited some portions of Devon- 

 shire and Cornwall, a small part of the typical Silurian country (of 

 Sir R. I. Murchison), a part also of the Cambrian groups of North 

 Wales, and lastly some groups of the newer fossiliferous slates of 

 Westmoreland and Yorkshire. I rejoice to ajJpear once more as a 

 fellow-labourer, and to lay the first-fruits of my summer's task before 

 the Geological Society. 



My present notice will be confined to Devonshire and Cornwall.
