which our limits will not allow us to notice. Chapter 20., On 

 the Geology of England and Wales, contains a more distinct 

 account of the secondary and tertiary formations, than was 

 given in the second edition. Our author is inclined to 

 believe that a range of primary mountains once extended, 

 from east to west, across this country, of which the Charn- 

 wood Forest hills, the low sienitic hills in Warwickshire, 

 and the Malvern hills in Gloucestershire and Herefordshire, 

 are the remaining nuclei; and that these hills were once 

 united, and opposed a barrier to the farther extension of the 

 upper secondary strata; for beyond these hills the lias, 

 oolite, and chalk, no where appear on the western side of Eng- 

 land. 



The present edition of this work contains one half more 

 letter-press than the second edition ; but are published at the 

 same price, being printed in a smaller type. 



A useful index and explanation of terms are added. From 

 the clear manner in which the principles of the science were 

 stated in the Introduction to Geology, and the variety of ori- 

 ginal information which it contained respecting the geology 

 of England, it contributed much to the diffusion of a taste for 

 geological encjuiries in this country. The present edition con- 

 tains all the principal discoveries that have since been made, 

 and is replete with much valuable additional matter, derived 

 from the author's extensive researches in Great Britain, and 

 various parts of the continent of Europe. T.

Botanical Periodicals. 



The Botanical Cabinet, for July, contains Catasetura Claveringi. An 

 orchideous plant, which roots into the decaying bark of the trunks of 

 trees in the Brazilian forests, and is therefore called an epiphyte, in 

 contradistinction to such plants as the mistletoe, which roots or fixes 

 itself into the living bark. If our readers will bear this distinction 

 in mind, they will be able to apply, with greater accuracy than is usually 

 done, the words parasite and epiphyte. — /Tyoscyamus orientalis; Pen- 

 tan. Monog., and iSolaneae. A new herbaceous plant from Caucasus. It 

 flowers in March and April ; from which circumstance, the young botanist 

 may conclude it to be of low growth ; since plants of the herbaceous kind, 

 which have to shoot up from the ground every year, before they flower, 

 cannot, by March, have attained any great height. 



' The Flora Australdsica, for July, contains Dryandra (Dr. Dryander, a 

 celebrated and well known botanist) formosa; Tetran. Monog. and Prote-
