XXVI PEOCEEDINGS OF THE GEOLOGICAL SOCIETY* 



in the notice of fossil plants in the Bridgewater Treatise, and in 

 the paper on Cycadeoidese, which adorns our Transactions** To 

 the subject of fossil botany he was, indeed, specially attached; 

 always glad to receive the additional information which new re- 

 marks; and especially new specimens, could furnish ; always ready, 

 but at the same time cautious, in giving his views on the difficult 

 questions frequently suggested by fragments of unknown plants* 

 His large collection of specimens of fossil woods is bequeathed to the 

 British Museum. 



Herbert Francis Mackworth, born 27th September, 18S3, in 

 Trinidad, died 13th July, 1858. Mr. Mackworth was educated at 

 King's College, London, and was appointed Inspector of the Mines 

 and Collieries in the southern district of England and Wales in 

 1851, an office for which he had prepared himself by previous em- 

 ployment as an engineer, and several visits to the mining districts 

 of England and Germany. 



Hugh Lee Pattijtson, born at Alston Moor in Cumberland, and 

 trained up to mining and metallurgy, distinguished himself by the 

 invention of a new and economical process for the separation of 

 silver from lead. He was a practical chemist and electrician, and a 

 liberal promoter of astronomy. Died 11th November, 1858* 



The Rev. George Peagock, D.B., Dean of Ely, born 9th April, 

 1791, at Thornton Hall, Denton, in the parish of Gainford, near 

 Darlington, Durham, died 8th November, 1858. 



Though the late Dean of Ely contributed no paper to the Geo- 

 logical fSociety, he gave to geology in the British Association the 

 valuable support which might be justly claimed of a profound ma- 

 thematician, on behalf of a branch of knowledge, some of whose 

 highest generalizations are based on astronomical truths, and whose 

 special plicenomena often involve researches into the laws of heat, 

 the mechanical conditions of rocks, and the interpretation of nu- 

 merical results. 



Henry Warbtjrton, M.A., E.E.S., born in London, educated at 

 Eton, and Trinity College, Cambridge, died 21st September, 1858, 

 aged 74. Devoted through a considerable part of life to the labours 

 of a Member of Parliament, he retained till the end the exceeding- 

 love of classical literature, and the strict habit of scientific thought 

 which had been inspired by his University course. These qualities 

 were manifested rather in his personal intercourse with the Eel- 

 lows of the Geological Society, than by his contributions to our 

 volumes. In fact, the addresses which Mr. Warburton read as our 

 President, in 1843 and 1844, have not been printed ; and the con- 

 siderable share which he really took in oui' labours is but feebly
