conditions, as in open places in woods where charcoal has been 

 burnt. 



I would direct the attention of the botanist to the marine Algae, 

 which would, I am convinced, yield an abundant harvest. Limited as 

 my researches were to a small portion of the coast, viz., between St. 

 Aubin's and Portelet Bays, a space of three or four miles in extent, I 

 yet collected more than sixty species, and amongst them Griffithsia 

 barbata. The study of these plants is most interesting, as many spe- 

 cies are to be found in every possible state of development, according 

 as they occur near high- or low-water mark, or on different aspects of 

 the rocks on which they are growing, &c. Thus, the Cladostephus 

 spongiosus, which, in the upper pools, appears to grow solely to 

 afford attachment to species of Conferva, Cladophora and Cera- 

 mium, in the pools near low-water mark, attains twice the size, and 

 is unincumbered with parasites. But the submarine vegetation is 

 worthy of all admiration. Nothing can exceed the beauty of the 

 groves of Halidrys siliquosa, here ten or twelve feet in height ; the 

 Chorda Filum, attaining a much greater length, with the upper por- 

 tions of its stems floating, in the most graceful curves, upon the sur- 

 face ; and the densely packed and lively green leaves of Zostera 

 marina ; all affording food and support to thousands of small animals, 

 and all pleasing in their turn. 



But I must close my imperfect sketch, well satisfied if others be 

 tempted to carry out these investigations to a greater extent than I 

 was enabled to do. 



I cannot omit recording my obligations to Dr. Robert Ball, of Dub- 

 lin, who kindly furnished me with one of his naturalists' dredges,* 

 which, when compared with the ordinary oyster-dredge, does three 

 times the work with half the labour. I have likewise to thank Miss 

 Turner, of Gorey, for specimens of Griffithsia barbata, Daysa venusta, 

 and many other Algae. 



I conclude with M. Piquet's List of Plants found in Jersey, but not 

 mentioned by Mr. Babington as natives of that Island, although a few 

 of them are recorded by that botanist as occurring in the other Chan- 

 nel Islands. 



Those species supposed by M. Piquet to have been either natu- 

 ralized, or in any respect doubtful natives, are marked by a star (*) ; 

 and those which occur in the other Channel Islands, as well as in 

 Jersey, by a dagger (f). The list includes sixty-six flowering plants, 

 and one fern.
