5S2 Free Remaiks on Mr. Greenougk's Geological Map. 



ample Memoir, illustrative of the whole ; instead of which, ex- 

 clusive of 11 pages of Names of Hills, that are only indicated 

 by Letters in the Map, and which therefore ought to have been 

 ruade capable oi pasting on to the mm gins of the Map (by being 

 printed only on one side, instead of hoih sides of the paper) be- 

 cause, wiihoui this addition to its Margins, the Map is incomplete 

 and in a great degree useless, only 5 pages and 6 lines are de- 

 voted, to the description of the Map, or the other proper sub- 

 jects of an accompanying Memoir. 



An awkward and lame sort of an Apology for the conduct \nir- 

 sued towards Mr. Smith (of which more anon) and acknowledge- 

 ments to some Individuals who have assisted the Author, occupy 

 full two of these pages; leaving only three pages to the histori- 

 cal and the descriptive account of the Map, and of the principles 

 on which it has been constructed ; those who may not have per- 

 used the Author's late Work on Geology, should not fall into the 

 mistake of supposing, that the paucity and absolute defectiveness 

 of this Memoir, will be found supplied by the sei)arate Work al- 

 luded to, because, in neither of them, is the least mention or al- 

 lusion made to the other ; indeed, how could this have been 

 done ? because, the " Critical examination oi the first principles 

 of Geology," criticises to an excess, so as to unhinge it, every 

 principle (which the Author notices, and as far as he has been 

 able) on which Mr. Smith proceeded, in commencing his Map, 27 

 or 28 years ago, and on which he prosecuted the same until, at the 

 very beginning of this Century, it was in a very sufficient stale to 

 have been published, as scores besides myself are still living to 

 testify, and to identify the 15-sheet Map (still in existence) which 

 Mr. Smith exhibited, to those whose NajJies (but not their Mo- 

 nies) he solicited as Subscribers, to a reduction of this Map, and 

 a Work describing it. 1 say sufficient state of perfection, to have 

 at that time justified its publication, had more adequate pecuniary 

 encouragement been given (ofwhich, more anon); because, to pre- 

 tend thatsogreat a Work as exhibiting the actual extent of Surface, 

 the numberand the order of super-position, of all the many Groups 

 of Strata, included in the space of the 15-sheet Map, could at that 

 period, or even in 1815, have been quite correctly accomplished, 

 or that these important objects are, even 7iow accomplished, bv 

 this Map of Mr. Greenough's, would argue, either a very shallow 

 acquaintance with ihe subject, in its practical details, or else, 

 little regard to truth in the Person advancing such pretensions. 



High encomiums are, at the end of the Memoir, passed upon 

 Mr, Thomas Webster, for his supposed matchless care and ac- 

 curacy, in drawing the Map and preparing it for publication; it 

 appears howeyer, that great deductions are due from this rcprer 

 sentationj particularly in what relatcb to that highly essential 



mailer.
