at that time, published. Besides, one point alone (the 

 Giant's Causeway itself) had been dwelt upon; whereas, 

 it ought to be, from the general construction of the country, 

 and the circumstances attending its basalts, that arguments 

 were to be sought, to establish a decided resemblance be- 

 t^veen Antrim and Auvergne, in oi'der to lead to the conclu- 

 sion he wishes to draw; to wit, that Antrim also was a a^oI- 

 canic country. 



Two views of the Giant's Causeway, published by Mrs. 

 Drur}', supplied the defect of other materials. 



The first argument he drew fi'om these views was, that, 

 as they exhibit our Causeway, standing at the foot of a 

 conical mountain, this must have been the volcano, whence 

 the current of lava issued, in which it was formed. 



Dr. Hamilton takes pains to shew, that Mr. Desmarest 

 was misled in this point; which I would willingly allow, if 

 it was the only instance in which he misrepresents our facts : 

 but, as, in every step he takes, he endeavours to mislead, I 

 will not precipitately acquit him, of the same intention, in 

 this instance. 



His next argument, to prove Antrim to be a volcanic 

 country, is, from a resemblance, he thinks he discovers, be- 

 tween the valleys of Mont d'Or, in Auvergne, and, what 

 he considers as, the skirts of mountains, in Mrs. Drury's 

 drawino's. 



I must confess, I cannot discover any resemblance, be- 

 tween the faces of our precipices, in these drawings, and
