into narrow ravines, leading by " ports" or mule-tracks into 

 Spain. Others end in a natural cul-de-sac, called a " cinque/' 

 surrounded on three sides by lofty walls of rock, and entered 

 by a narrow gnlley from the valley on the fourth. At the 

 head of the lower valleys lie the celebrated Pyrenean " spas/' 

 a few of which also occupy higher and cooler situations in the 

 gorges. From valley to valley the ridges are crossed by "cols/' 

 generally lofty, and wild in their scenery — often diversified by 

 cascades, or even by snow-drifts and mountain-lakes. 



In these hill-fastnesses the box-tree is one of the most 

 common forms of shrub, and there exists an abundant variety 

 of wild-flowers, more like our own British flora — apparently 

 from the neighbourhood of the Atlantic Ocean — than those 

 met with in the more continental valleys of the Alps. A col- 

 lection of specimens procured, and dried in August, 1865, 

 occurring high and low in the Pyrenees, west of the Adour, 

 presents us with an exactly equal proportion of British and 

 foreign species. Those of our readers who study the pages 

 of Linnaeus and De Candolle, will meet with many familiar 

 acquaintances in the following list : —
