AUTHOR'S PREFACE. 



In the volume " The Jurassic Flora. I. The Yorkshire 

 Coast," issued in 1900, I dealt exclusively with specimens 

 in the British Museum and in other collections obtained 

 from the Inferior Oolite plant-beds of East Yorkshire. In 

 the present volume are included plants from Jurassic rocks 

 in various parts of England, together with a few from the 

 Coralline Oolite and Liassic strata of East Yorkshire. 

 A short account is also given of such Triassic and Rhsetic 

 plants as are represented in the Museum collection. 

 References will be found in the following pages to Jurassic 

 specimens in several provincial museums. 



My work in various museimis has been greatly facilitated 

 by the ready help afforded by those in charge of the 

 collections. I wish to offer my thanks to Professor SoUas 

 for his kindness in allowing me access to the rich collection 

 of Stonesfield fossils in the Oxford Museum, and for 

 affording mo an opportunity of having several specimens 

 photographed. Mj- thanks are due also to Mr. E. T. Newton 

 for the friendly assistance which he has repeatedly given 

 me in my examination of fossil plants in the Jermyn Street 

 Museum. I am indebted to Dr. Hoyle of Manchester, to 

 Mr. Platnauer of York, to Mr. Newsham of Whitby, and 

 to Mr. Slater of Malton for the loan of specimens. I wish to 

 express my thanks also to Mr. A. M. Bell of Oxford for his 

 courtesy in showing me his private collection of Stonesfield 

 plants, and for lending me the fossil which I have made 

 the type of a new species, Sphenozamites Belli.
