self on Cunnemara, and by Air. Moore in the north of Ireland ; amongst 
those was Erica mendisia, a plant with a beautiful white flower, 
hitherto much in request among cultivators. A number of curious 
varieties of the plant, known in gardens by the name of London 
Pride, were reported as indigenous to several parts of Ireland. 
“ A member stated that, in travelling from Edinburgh to Dublin, 
he was struck with the peculiarity of vegetation exhibited in the several 
districts through which he passed; plants of various tribes, abundantly 
diffused in one, were gradually lost as he proceeded to the next, and 
other productions, unknown to the place he had left, growing in 
profusion and luxuriance. 
<e A conversation on the locality of plants took place, involving some 
interesting questions, by which the various physical states of the 
atmosphere are indicated in different portions of the empire, and the 
susceptibilities of certain species and families of plants which inhabit 
them. 
“ On a previous clay, Mr. Niven, curator of the Glasnevin Botanic 
Garden, read a paper on the natural arrangement of plants, and pre¬ 
sented some specimens of new plants found in Wales, on the western 
coast of England. Air. Robert Ball reported the discovery of some 
new plants on the Hill of Howth. Air. Babbington informed the 
meeting that he had found Scirpus sevie in abundance in Anglesea, 
near Holyhead. Dr. Graham said he found it also at Galloway, in 
Scotland. The Doctor also found the Orchis pyramidalis [.Anacampis 
pyramidal is'] in the same place. Air. Babbington said, three of the 
ranunculus tribe were commonly confounded under one—the aquatilis, 
palustris, and circmatus. Air. Babbington also informed the meeting 
that Reichenbach distinguished three distinct species under the head 
Orchis hifolia , two of them natives of Great Britain ; they were chiefly 
distinguishable by the form of the anthers—one round, the other elon¬ 
gated. A communication was read from Air. Hamilton, of Mexico, 
offering his services to the British Association in forwarding seeds and 
plants, and describing some new plants of that country, one of which 
was a Solanum. 
“ Air. Nicol read a paper on the structure of the horizontal branches 
of the natural order Coniferce. This is highly useful to those who 
study the fossil remains of vegetable substances. Air. Alackay sub¬ 
mitted several specimens of bog-timber, some Scotch fir found 
eighteen feet under the surface; also some specimens, with marks of 
their being charred when they fell. He also detailed the uses made of 
bog-timbers in Ireland. Air. Alackay, on a subsequent day, stated that, 
when in the neighbourhood of Killarney, he was informed of an extra-
