xii STUDIES IN FOSSIL BOTANY 



section or specimen illustrated, in the collection to 

 which it belongs. The abbreviation " Will. Coll." 

 indicates the Williamson Collection (now in the British 

 Museum, Natural History Department), while " S- 

 Coll." refers to my own collection. In other cases the 

 name is given in full. 



The progress of scientific fossil botany has been 

 greatly advanced by the skilled and intelligent work, 

 in collecting petrified specimens and preparing sections, 

 of such men as Mr. J. Lomax, Mr. G. Wild, and their 

 colleagues, now deceased, Mr. J. Butterworth, Mr. J. 

 Spencer, and others. 



The references to the literature make no pretence 

 to being exhaustive ; I hope, however, that the works 

 of chief importance to the botanical reader have been 

 cited, and that justice has in all cases been done to 

 those who have laid the foundations of our knowledge.
