The Excursions of 1886. 

 Having regard first to the whole-day excursions — 

 May 1st. — Three members and one visitor only made the 

 party. Under the guidance of Mr. F. G. Carey, the party 

 having met at Epsom Station, proceeded first to the mineral 

 well, which at one time was a place of considerable resort. 

 The well is now in private grounds, about one mile south- 

 west of Epsom Station. It is not used for medicinal purposes. 

 Dr. Bossey took a sample of the water, and also of the sedi- 

 ment at the bottom of the well, at a depth of about 12 feet. 

 The water contained some living animalcules (Vorticellfe, 

 Paramecia, a Eotifer, and an Annelid). The sediment con- 

 sisted of sand, clay, chalk, building-rubbish, and much 

 decaying vegetable-matter, all of them suggestive of some 

 inlet of impure surface-water. Sand was present, consisting 

 of portions of quartz, colourless, opaque, with yellow and 

 brown sand. There were particles of clay and chalk. Leaving 

 the well, the walk was continued over Epsom Common, and 

 then through a lane leading to Ashstead Park. There was 

 some remarkably fine timber, consisting of Oak, Elm, various 

 kinds of Fir, and some very old Yews. A Eoman stone street 

 formerly passed through the Park, and some relics of it are 

 said to be found in the material of which the church is built. 

 The remainder of the excursion was confined to the high 

 road through Leatherhead to the Box Hill Station of the 

 South Eastern Eailway. 



June 2nd. — This excursion was to Tunbridge Wells, to 

 meet members of the Tunbridge Wells Natural History 

 and Antiquarian Society. About ten members of the Holmes- 

 dale Club were present, and a considerable number of the 

 Tunbridge Wells Society. The excursion was directed to 

 Eridge Castle, which dates from about the 13th century, but
