ANNIVERSARY ADDRESS OF THE PRESIDENT. XXIX 



From this period to the last hour of his Ufe Mr. Greenough was 

 actively employed in forwarding the interests of this Society, and in 

 advancing the progress of geology and physical geography. He was 

 unceasingly occupied in increasing his valuable collection of maps, 

 and in entering on them and in his numerous note-books all the 

 geological data which he could obtain either from books or from the 

 communications of scientific travellers. But notwithstanding his 

 vast collections and his numerous and elaborate notes on every sub- 

 ject connected with mineralogy, geology or physical geography, Mr. 

 Greenough was not a great writer. No memoir from his pen, except 

 his presidential addresses, has been published by any of the learned 

 Societies to which he belonged. 



About this period, also, Mr. Greenough was made an Honorary 

 Member of most of the scientific societies of the United Kingdom ; 

 and, notwithstanding the war with France, he received in 1809 the 

 diploma of Honorary Member of the Agricultural Society of Bou- 

 logne. During the next succeeding year he was actively employed 

 in pursuing his geological explorations in various parts of Great 

 Britain and Ireland, preparing for that great work which he was 

 already contemplating, the Geological Map of England. In 1814 

 he started for Paris the very day after the Treaty of Peace was 

 signed. Soon afterwards the state of his health, brought on probably 

 by severe mental and bodily exertions, compelled him to take up his 

 residence at Cheltenham ; but in 1818 he was again elected President 

 of this Society. 



In 1819, after years of labour in the collection of the materials 

 and the arrangement and construction of his work, he published his 

 Geological Map of England and Wales, in six sheets, vdth an accom- 

 panying memoir, compiled from an extensive collection of maps and 

 surveys. In order to render this work as perfect as possible, Mr. 

 Greenough spared no efforts, and was equally willing to avail himself 

 of the information collected by his numerous geological friends as by 

 himself. He ever retained a grateful sense of the pecuniary assist- 

 ance given him by Mr. Warburton, who had at one time contributed 

 as much as a thousand pounds towards the work, a great portion of 

 which, if not the whole, was subsequently repaid. 



In the same year Mr. Greenough published the only work on 

 geology which issued from the press under his own name, and when 

 we consider the talent shown in this work, the ingenuity displayed in 

 controverting those geological theories which he considered injurious 

 to the science, and at the same time recollect the mass of information 

 he had collected, and the systematic way in which it was arranged in 

 those many MS. volumes which must be well known to all who had 

 the good fortune to be intimately connected wdth him, we cannot 

 but regret that Mr. Greenough should not have made more use 

 of his materials, and have devoted some portion of his time to the 

 publication of Principles of geology better adapted to the progress of 

 the science wdthin the last ten years than the work to which I am 

 now alluding. Under the title of * A Critical Examination of the 

 First Principles of Geology,' in a series of essays, Mr. Greenough
