I. A Review of the First Volume of M. J. A. De Luc's 

 Geological Travels in the North of Europe : with Re- 

 ma? ks on some of the Geological Points which ara there- 

 in discussed. By a Correspondent, 



To Mr. Tilloch. 



Sir, As a reader of your Magazine, I have been much 

 gratified of late, by the extracts, remarks, and observations 

 which have been given by you, or communicated by your 

 correspondents, on subjects connected with Geology, or 

 Geognosy, as it seems now the fashion with many to call 

 it; and having just finished the perusal of a very useful 

 as well as entertaining work, the first volume of M. J. A. 

 De Luc's Geological Travels in the North of Europe, very 

 lately published, I beg to communicate a short account of 

 the same. The travels which are detailed in the present 

 volume, were, it seems, undertaken, for collecting an ex- 

 tended body of facts in refutation of certain tenets of the 

 late Dr. Hutton, and other geological writers, and ii> con- 

 firmation of the doctrines advanced by the author in his 

 " Elementary Treatise on Geology," lately published. The 

 route of our author commenced on the 23d of July 1804, 

 at Berlin ; he proceeded by way of Zehdenick, Furstenberg, 

 Strelitz, Malehin, Lague, Rostock, Wismar, Travemiinde, 

 Lubeck, Eutin, Kiel, and Sleswigh, to Husum ; from 

 whence, on the 26th of August, he embarked for Harwich, 

 to pursue a similar course of investigations in England, the 

 details of which are to form the subject of his second 

 volume, the publication of which will not I sincerely hope 

 be long delayed. 



The objects of M. Dc Luc's travels here detailed, are 

 first stated in 27 propositions or heads : the first eleven, and 

 the 13th, 14th, and 13th of which, relate to the question,
