16 Anniversary Address. 



F. Douglas, in a stroll to Tantallon, also picked abundance of 

 this Scabiosa. On the way to Canty . Bay, I picked the 

 Ononis arvensis in quantity, with white flowers. On a pre- 

 vious visit, Mr. Hardy observed the corn-fields to be infested 

 with Papaver argemone, P. rhceas, and P. dubium ■ and that 

 the gaudy corn flower, Centaurea cyanus, now almost extinct 

 in Berwickshire, grew near Drem and again towards White- 

 kirk. While waiting for the boat at Canty Bay, Mr. Sadler 

 observed many beautiful sea- weeds. In one pool in particular 

 he was much struck with the luxuriance of Laminaria 

 Saccharina, Delesseria sanguined, D. alata, Chorda fclum, 

 and Corallina officinalis. In this pool there was a splendid 

 specimen of Actinia, and several specimens of Medmce and 

 Beroe swimming about. At the point where the boats 

 started from, there was abundance of fine specimens of the 

 dark olive green Himanthalia lorea, with fronds from one 

 to four feet long, with their curious button-like discs. Some 

 splendid specimens of Laminaria digitata were seen, as well 

 as all the common sea- weeds : such as Fucus nodosus, F. 

 serratus, F. vesiculosus, Ulva latissima, Enteromorpha intes- 

 tinalis,&LC. The two representative phsenogamus plants of the 

 Bass are the tree mallow, Lavatera arborea, and the sea-beet, 

 Beta maritima — which were got ; and the Lychnis dioica, 

 with very large leaves — was growing in profusion every- 

 where above the landing-place on the rock. 



The Bass is 420 feet above the sea-level and is a mile in 

 circumference, and the water around is considered to be 200 

 feet deep. It is composed of an augitic greenstone, generally 

 fine and granular, but sometimes so abounding in felspar, as 

 to verge on clinkstone. It exhibits in a very marked 

 manner the tabular structure, as is also the case in the 

 similarly composed Isle of May. On the north side it is 

 most precipitous, and the sea view is particularly impressive. 

 Its superficies is guessed at seven acres. A cavern-like 

 passage penetrates through the rock from N.E. to S.E. The 

 cavern is passable even at full tide, if the sea be calm. The
