OTTTLIXES OEGEOLOG Y.— By T. Allison Eeadwin, E.G.S. 

 Containing an Outline of the Science, and a Revised Table of the Order of 

 Superposition of British Rocks, with their characteristic Minerals and Fossils, in 

 accordance with the arrangement at the Museum of Practical Geology, Jermyn-st. 



" This pamphlet, though a mere outline of geology, contains some tahles useful for the clear compre- 

 hension of the subject, and one of which (Table No. 3) is remarkably full of geological informatiou re- 

 specting the fossils, minerals, rocks, and strata of Great Britain. The classification herein adopted is very 

 correct, and perhaps is not surpassed, if equalled, in this respect, by any treatise or text-book hitherto 

 published. References to the cases of fossils in the Jermyn-street Museum accompany this table, so as to 

 render it a useful handbook for the visitor to that institution." — Literary Gazette, Jan. 30, 1858.
