of the tertiary period, a question naturally arises as to the continu- 

 ance and destruction of that early flora, and also as to the character 

 of the vegetation during the tertiary sera ; whether it did, like the 

 present indigenous one, contain some forms representative of the 

 earlier flora. Future researches may throw some light on this point. 

 The subject matter is treated geographically under eight sections, and 

 altogether the work is a very acceptable one, and will prove useful 

 both to the scientific inquirer and the emigrant : the descriptions of 

 the physical features, as dependent on the geological structure, are 

 briefly but clearly stated. Much, however, remains to be effected ; 

 and we do not doubt that through the zealous and active labours of 

 the Rev. W. B. Clarke, as well as in the appointment of a government 

 geologist now proceeding on his mission, our knowledge of the pe- 

 culiar structure, mineral riches and fossil character of the various 

 rocks occurring in this important colony will be materially increased 

 and elucidated. 



Outlines of British Geology. Published for the Society for promoting 

 Christian Knowledge. London, 1850. 



This is a useful introduction to the study of British geology, em- 

 bracing a general account of the principal formations occurring in 

 England, with brief notices of those in Scotland and Ireland. In the 

 descriptions of the range and extent of the more important strata, 

 their physical and agricultural characters, the author has availed 

 himself of some of the chief English works on the subject, although 

 at the same time it is evident he has been an attentive observer of 

 many of the described plisenomena. The subject is treated in a very 

 popular manner, devoid of all technicalities, and will form a good 

 compendium to this science for the young student. 



A copious glossary, explaining the terms which generally occur in 

 geological works, and the nature and composition of the principal 

 mineral substances, is appended to the volume, as well as a geological 

 map and a few sections, illustrative of the sections of the strata tra- 

 versed by the principal railways from London.

The Ichnology of Annandale, or Illustrations of Footmarks impressed 

 on the New Red Sandstone of Corncockle Muir, Dumfries-shire, 

 By Sir William Jardine, Bart., F.R.S.E., F.L.S. &c. 



The illustrations now contemplated will consist of about Twelve 

 Plates, lithographed from the "impressions on the sandstone." From 

 the difficulty of properly representing these reduced, they will be 

 figured of the size of the originals, and will be printed in colours so 

 as to represent the precise appearance of the sandstone as nearly as 

 possible. A few necessary and explanatory observations will accom- 

 pany the plates.
