that C. Tussilaginis was a species which apparently most nearly 

 resembled the cultivated Cineraria. 



White Narcissus, Artificially Coloured. — Dr. Russell ex- 

 hibited some cut flowers of white Polyanthus Narcissus, which 

 he had placed in solutions of acid red magenta (Judson) dye, 

 and in acid green. The colours had traversed the fibro-vascular 

 cords, and then spread over the intermediate tissues, forming a 

 border round the ends of the petals. He proposes investigating 

 the matter to try and discover the general nature of those 

 colours which will act in this way. It took from 12 to 

 15 hours to infuse the perianths. Mr. Henslow remarked 

 that John Laurence in his book on gardening (1726), says that 

 people in his day used to colour flowers by letting the roots lie 

 in a solution of the lees of claret. 



Scientific Committee, February 9, 1897. 

 Dr. M. T. Masters, F.R.S., in the Chair. 



Coniferous Woods. — Dr. Masters exhibited specimens of 

 Deodar, Larch, and Cedar of Lebanon, grown by Mr. J. Simpson 

 at Wharncliffe. They were said to have been planted at the 

 same time, about thirty years ago. It was remarkable that the 

 heartwood of the larch and deodar were much alike, while 

 that of the cedar was different, in not being so darkly coloured 

 as the others. The quality was in each case good, especially 

 that of the larch. It has been observed by Dr. Tristram that 

 the wood of the cedars grown on Mount Lebanon is much 

 closer in grain and darker in colour than that of trees grown in 

 England. (« The Nat. Hist, of the Bible," p. 343.) 



Species of Thuya. — Dr. Masters also exhibited specimens 

 from Mr. A. D. Webster and others, illustrative of the con- 

 fusion in the nomenclature of this genus. He observed that 

 T. occidentalis grows in the Atlantic States of North America, 

 and T. gigantea (Lobbi) on the north-western or Pacific side. 

 A form originally named T. plicata was introduced at the end 

 of the last century by Menzies from Vancouver. In Donn's 

 " Catalogue of the Plants of the Botanic Gardens at Cambridge " 

 this plant is recorded, but without description. As this is a 

 western species, it is really synonymous with, or at most, a
