8 INFERIOR OOLITE AMMONITES. 



Artists, and all who have assisted in the production of this volume, and to all who 

 have in so many ways kindly rendered services, scientific or technical, in con- 

 nection with this work and its associated studies, the writer cordially expresses his 

 most grateful thanks. 



With this work the author desires to associate three names — that of the late 

 Dr. Thomas Davidson, F.R.S., one of his earliest geological friends, from whom he 

 experienced much kindness and encouragement; that of Mr. R. D. S. Darell, 

 F.L.S., F.G.S., formerly Mr. Darell Stephens, one of his earliest companions in the 

 field, from whom he received many practical lessons in the zonal distribution of 

 Ammonites (what the immense collection formed by Mr. Darell' s enthusiastic 

 labours has added to our knowledge of Ammonites is partly shown in these pages 

 and plates) ; and that of his late father, Prof. James Buckman, from whom the 

 author received so many scientific lessons, and to whom he owes his taste for 

 scientific work. It was the father's great desire that his son should undertake 

 the describing of the Inferior Oolite Ammonites — a task which he himself had 

 formerly hoped to achieve. 



Finally, the author desires to dedicate this work to his wife, his companion in 

 many geological excursions, to whose skill he owes a number of good specimens. 

 These words are written in the month which sees the completion of twenty-five 

 years of married life, and the receipt of the many kind congratulations incidental 

 to a silver wedding.
