254 PROCEEDINGS OF THE 



Circaea lutetiana grew luxuriantly in some parts of the glen. The 

 ripe, ruby-like, somewhat insipid fruit of Rubus saxatilis was 

 gathered. Polypodium Dryopt&ris was not uncommon. Among 

 the mosses found was Hooheria lucens in fruit. The abundance of 

 agarics and other large fungi drew, however, most attention. Of 

 such plants the following were collected : — Agaricus vaginatus, A. 

 rubescenx, A. rut Hans, A. terreus, A. laccatus, A. epixanthus, A. 

 fascicular is ; Lactarius insidsus, L, blennius, L. quietus, Russula 

 nigricans, R. adusta, R. heterophylla, R. foetens, R. emetica, R. 

 fellea, Cantltarellus cibarius, Boletus Jiavus, Pohjporus betulinus, 

 Hyduuin rejpandum. Several leaf-fungi were observed, Pnccinia 

 Saniculae being especially plentiful. The Chantarelle and the 

 Hydnum were collected for cooking purposes. Several of the 

 members explained to the meeting the modes of cooking they had 

 adopted, and expressed their satisfaction with the two kinds made 

 use of, as pleasant and wholesome articles of diet. 



Mr. T. Boyle exhibited a piece of grey chalk obtained in boring 

 the Channel Tunnel, and containing a profusion of foraminifera. 

 Mr. P. Ewing exhibited a white-flowered form of Centaurea nigra, 

 some other abnormal plants, and a curious gall growing on a 

 Hieracium, that of an insect of the genus Aulax. Mr. D. Gregorson 

 shewed specimens of Carduusacanthoides from Scotstoun ; and Mr. 

 Thomas King, a series of rare mosses which he had collected on the 

 Ochils, on the 22nd of August, including Leskea rufescens, 

 Encalypta ciliata, Bryum julaceum, and Dipliyscium foliosum. 



Mr. Thomas King read a paper on the Equisetaceae. He 

 explained their structure and the morphological significance of the 

 different parts, and described the way in which the branches are 

 disposed in whorls at the nodes. The sheath is generally con- 

 sidered as being formed of leaves united at their base, but Sachs 

 regards it as simply a leaf-sheath toothed at its margin. He 

 described very fully the internal structure of the stem, and referred 

 to the fossil representatives of the family. 



In the discussion that followed, the Chairman, Mr. Young, 

 described some interesting fossils lately discovered in Liddesdale, 

 which are considered to belong to the same group of plants. 



Mr. R. Turner read a paper on " Spring Rambles in Sussex." 

 He described the Chalk formation as observed at Lewes, and entered 

 more fully into the geological features of the cliff's at Hastings, 

 which belong to the Wealden series, exhibiting fossils and rock-
