flavus, and others which were not identified. Many of the 

 briUiantly-coloured Eussulas were also found ; and Lactarius 

 deliciosus, recognisable by its bright orange milk, and coloiu- 

 changing to green when bruised ; L. torminosus, and L. quietus. 

 The curious, almost spherical Sclerodenna vuhjaris was also 

 met with, hard and intensely black within, and with a strong 

 disagreeable odour. Amongst the plants characteristic of the 

 Forest are — Campanula hederacea, which grows abundantly in 

 most parts ; Scutellaria minor, found almost everywhere ; 

 Narthecium ossifragtim, growing by one of the large hammer- 

 ponds; Hypericum elodes, in marshy places ; Anarjallis tenella, 

 often found growing with Campanula hederacea, but much less 

 common. Ferns are very abundant, especially Lastrea 

 dilatata, L. Oreopteris, Athyrium FiUx-fcemina, Aspidiiun 

 Filix-mas, and Blechnum boreale, all of which species luxuriate 

 in the localities respectively suited to them. Comparatively 

 few birds were observed : two flocks of Wild Ducks, or perhaps 

 the same seen twice, were flying round some of the ponds or 

 swimming among the water-plants ; they consisted of about 

 twelve birds each — doubtless the pair of old birds and their 

 brood hatched early in the year. The cry of the Green 

 Woodpecker and Jay were heard occasionally, and an indi- 

 vidual of the latter species was seen. The party walked for 

 several miles through the wooded parts of the Forest, in a 

 south or south-westerly direction, and on emerging from the 

 woods turned east, and soon after crossed the railway not far 

 from the north end of the Balcombe Tunnel. Passing along 

 a sort of rough track in places somewhat boggy, the minute 

 and delicate little plant Cicendia filiformis was discovered 

 growing abundantly in wet parts, extending about fifteen 

 yards along the path ; this is a rare plant in our district, and 

 Tilgate Forest is our only recorded locality ; so extremely 

 small a plant may, however, be very easily overlooked. A 

 quarry was passed where the Hastings Sand appeared in the 

 form of beds of soft friable sandstone ; small blocks had been 

 quari'ied for use in making paths in gardens and similar pur- 

 poses, not being hard enough for building purposes. In one 

 of these blocks a cast of a Paludina w;is noticed. By the
