INTRODUCTION. 



As Gibraltar has so often been described by various 

 writers, the reader will perhaps be disappointed in 

 not finding in my topographical observations any 

 sufficient reason for another account of the far-famed 

 rock ; however, as the object of the present work is 

 to give an outline of important and interesting facts, 

 and to combine the purposes of general utility, as 

 well as to satisfy the curiosity of the naturalist, it is 

 to be hoped that so far the author has succeeded in 

 his wishes. The elaborate works of Dr. Hennen, 

 Montgomery Martin, and Drinkwater, and several 

 others of less note, may be consulted with great 

 satisfaction by those who are curious to know more of 

 this important and powerful fortress. I regret that 

 Mr. Smith's geological account of the rock was not 

 published until most of this work had been printed,
