24 TANGLES. 



specimens are exposed to the sua's rays, the purple 

 ones are such as have grown in deep shadow. The 

 species is the Laurencia pinnatifida of botanists. 



Turning from ' the hidden clefts, we explore the 

 deep pools that lie between the ledges. High wading- 

 boots are necessaryfor this purpose, as we have to 

 work in the water. The great Oar-weeds and Tangles 

 (Laminaria) are growing here, large olive s5a-weeds 

 that wave to and fro with the undulations of the sea ; 

 the former a long narrow puckered frond of brown 

 colour; the latter a broad smooth leathery expanse 

 of deeper colour on a slender stalk, splitting with age 

 into a number of lengthened fingers or ribbons, and 

 hence called the fingered Tangle (Laminaria digi- 

 tata). Among these grow clusters of an elegantly 

 frilled species, of delicate thin texture, and yellow- 

 brown hue, bearing no slight resemblance to the 

 tresses of some fair lady : this also is a Laminaria, 

 but I am not quite sure whether it is the young state 

 of the former species, or jentitled to a name of its own. 

 In the latter case, it is the L. phyllitis of botanists 

 {See Plate VI). One result of the establishment of 

 Marine Aquaria will be a more general acquaintance 

 and consequently a better and more satisfactory one, 

 with the tenants of the sea, than has hitherto been 

 practicable; since they can now be sudied to far 

 greater advantage than when blanched in bottles of 

 spirits, or pressed between the leaves of a book. 



In these deep pools grew also those bunches of 

 broad dark-red leaver, which are probably the most 

 conspicuous of all the marine plants in the collection. 

 My readers will recognise them, when I say that they
