perience of its peculiar aromatic odour furnisliing au inseparable 

 accompaniment to an excursion in hot weather amongst the hill 

 country; and yet^ although I have heard sometimes from the 

 farmers and labourers of its being used medicinally^ I do not 

 remember to have seen it once under cultivation. Amongst the 

 western hills it grows plentifully in every dale of the series from 

 Teesdale southward to Calderdale, often beginning before houses 

 and cultivated fields are reached. On the east it occurs by the 

 side of almost all^ if not all^ the tributaries of Esk^ Leven_, Hye, 

 and Derwent, that take their rise in the moorland country, in 

 two or three stations in the Howardian district, and sparingly 

 at the foot of the western and southern slope of the Hambleton 

 Hills; but the wide tract of intervening level country it avoids 

 entirely, except where manifestly carried down by the rivers. 

 Taking into consideration, first, the rarity or non-existence of 

 its cultivation ; secondly, the nature of its localities and its 

 frequency in them ; thirdly and mainly, the fact that in. the 

 ensemble of its dispersion throughout the district it is quite on a 

 par, nay, exceeds the commonest subalpine plants of the county, 

 TroUius europcBus and Stellaria nemorum for instance, I do not 

 see that there is any reasonable probability that it has been in- 

 troduced by human agency at any period however remote. A 

 little lower down the gill I gathered Hypnum heteropterum and 

 H. chrysophyllum upon shaded rocks, and crossing by a footpath 

 to the high-road that leads to Beamsley, took another peep at 

 Bolton Abbey, and in the evening returned again to Ilkley." 



He exhibited specimens of four naturalized Grasses, gathered 

 by Dr. Carrington in the vicinity of a paper-mill in the neigh- 

 bourhood of Bury, in Lancashire, — Panicum capillare, Setaria 

 glauca, Digit aria sanguinalis, and Eleusine indica. The three 

 first-mentioned are natives of southern Europe, the other of 

 Hindostan. 



Mr. J. H. Davies exhibited examples of the following Mosses, 

 viz. Orthotrichum fastigiatum, Kildare, Beech-trees at Ballitore ; 

 O. tenellum, Kildare, Beech-trees at Fuller's Court garden, and 

 Willows by the Griese, below Ballitore ; Tortula papillosa, North 

 Yorkshire, on Hawthorn between Thirsk and Woodend.
