��NOTES ON THE DISTRIBUTION OF ALGiE.

By G, Dickie, A.M., M.D.

{Read at the Meeting of the Botanical Society of Edinburgh, Jan. \2th, 1871.)

The result of dredging near the " Maiden Eocks" in relation to range in depth of Algfe, formed the subject of a paper to the Society in 1869 ; having some years before made a passage in the lighthouse tender from Larne, the nearest port, I have thought that notes of the AlgjB found on them might deserve to be recorded, especially when contrasted Avith those of the neighbouring shore. The " Maidens" are about six to seven miles from the Antrim coast, they are in close proximity, of small extent, and each mainly occupied by lighthouse-buildings, presenting but few crevices where land plants can grow, of which I only found three, viz. Matricaria iuodora, var. /3. maritima, and two species of Atriplex. The two small islands in question rise abruptly, having deep water near them ; they are in fact the rugged tops of a submerged mass of basalt.

The visit was made about the end of June (a month or two later would have been more favo\irable), the time allowed was limited ; I, however, col- lected every seaweed that could be seen, and all were kept separate in my herbarium.
