one may venture to say that it would have been greater had his early 

 studies been more turned in the direction of mathematics, especially as ap- 

 plied to physical research. In the beginning of his career, indeed, Che- 

 mistry was only acquiring numerical exactness, and Geology was quite un- 

 provided with mechanical laws of earth-movement. But no one knew 

 better than Dr. Daubeny that right geometrical conceptions are always 

 necessary to a student of science, and laws of proportion indispensable 

 elements of sound philosophy. 



The published writings of Dr. Daubeny are very numerous. Besides 

 what have appeared as independent works, the list of his Memoirs in 

 Transactions and Journals up to 1883, as given in the Royal Society's 

 <c Catalogue of Scientific Papers," amounts to seventy-too. Many of 

 these, scattered through various periodicals and not conveniently accessible, 

 were collected and arranged by their author in two volumes of Miscellanies. 

 In this collection appeared twelve Experimental Essays, ten Geological 

 Memoirs, eight Essays on Scientific Subjects, and twelve on Literarv 

 Subjects. Besides these were several papers of interest, some published 

 separately, which, having been composed after the first edition of the * De- 

 scription of Volcanoes,' were employed in the preparation of the second 

 edition, or noticed in supplements to that work. 



By these arrangements Dr. Daubeny has rendered it unnecessary, for 

 those who desire to know his views on the various subjects which occupied 

 his mind, to refer to such publications as the Edinburgh Philosophical 

 Journal, Edinburgh New Philosophical Journal, or Journal of the Geolo- 

 gical Society, or even to the Linnean Transactions, Royal Society's Trans- 

 actions, or Reports of the British Association, except from a desire to 

 learn his first thoughts from his first words. The following is a list of the 

 works which contain the principal results of Dr. Daubeny's scientific and 

 literary labours : — ■
