by Mr. J. R. Lee, the most notable species was Br uum 

 roseum , Schreb. 



Among the Alg?e noted by Mr, George Lunam, reference may 

 be made to Batrachospermnm moniliforme, Roth, which was so 

 abundant as to cover many of the rocks in the streams, and to 

 Draparnaldia plumosa, Vauch., D. glome.rata, Ag., and Tetraspora 

 gelatinosa, Desv., which were also plentiful. 



Fungi were investigated by Mr. R. B. Johnstone, who obtained 

 a few of the larger forms, including Coprinus plicatilis, Fr., 

 Polyporus squamosus, Fr., Mitrula phalloides (Bull.) Chev., &c. 



Braidwood to Tillietudlem, 6th June, 1908. — Mr. John 

 Robertson, conductor. In brilliant weather six members pro- 

 ceeded by rail to Braidwood Station. The route taken was down 

 alongside Fiddler Gill, and through the orchards to Crossford, 

 where a halt was made for tea. The road by the Nethan was 

 afterwards followed to Craignethan Castle and Tillietudlem 

 railway station. 



As time only permitted a pleasant ramble, little of note was 

 observed. Only four birds' nests — two Blackbirds and two White- 

 throats — were seen. The Mistle Thrush was heard in full sona'. 

 This was a point of some interest, as the conductor had never 

 before heard the spring notes of that bird so late as the 6th 

 of June. 



Among Flowering-plants, mention may be made of Paris 

 quadrifolia, L., and Neoitia Nidus-avis, Rich., both seen in 

 Fiddler Gill; and of Ranunculus bulbosus, L., Cheiranthus Cheiri, 

 L., and Arum maculatum, L., observed at Craignethan Castle. 



Rosneath, 27th June, 1908. — Report by Mr. John Renwick. 

 In the little glen near the pier, patches of Heart-leaved Valerian 

 (Valeriana pyrenaica, L.) and Orpine (Sedum Telephium, L.) were 

 seen. The grounds of the Clachan House were visited, to see the 

 famous triple avenue of Yews, Limes, ifcc. The largest Yew 

 (Taxus baccata, L.), a female, has a bole of 10 feet, and a girth of 

 12 ft. 2 in. at 2 ft. 6 in. up, showing an increase in girth since 

 1895 of 9^- in., an average of about T 7 ^ in. yearly, which is a 

 considerable growth for a Yew-tree. The largest Lime (Tilia 

 vulgaris, Hayne) has a bole of 9 ft., and a girth of 14 ft. 3A in.
