of interest as lying on the watershed of the Darenth and Med- 

 way. The walk was subsequently prolonged over the high land 

 of Chart Common by Moor House to Westerham, and the 

 majority of the members returned to Oxted in time to catch the 

 last train to Croydon. The weather was exceedingly fine. Mr. 

 Topley supplied the members with a sketch map and geological 

 section of the district. 



The last excursion of the season was on Saturday afternoon, 

 the 15th of September, from Epsom along the east side of 

 Durdans and Woodcote Parks, thence through Ashtead Park to 

 Ashtead Church. The day was fine, but only 5 members joined 

 in the excursion. 



Meetings. 



The following Papers have been read at the Monthly Meetings : 



February 8th. — " Foraminifera and other Micro-organisms in 

 Flint," by the Eev. George Bailey, F.R.M.S. (Trans., Art. 66). 

 In this communication Mr. Bailey gave the results of an exami- 

 nation of a series of preparations from some hoUow flints col- 

 lected on the 11th of April, 1884, during an excursion of the 

 Club to Down and Cudham. In the discussion which followed 

 questions were raised as to the presence of organisms on the 

 outside of flint nodules as well as inside. How was the mealy 

 powder in the hollow flint formed ? What are Xanthidia, and 

 where are they formed ? And what are the processes of treat- 

 ment most suitable for the treatment of flint organisms ? In 

 replying Mr. Bailey described the process of treatment adopted 

 by himself in the preparation of slides. The mealy powder was 

 carefully separated from fragments of flint, put into a beaker- 

 glass containing clean water, and well shaken ; the sediment 

 was allowed to settle and the water gently poured off. This 

 simple washing was repeated until all milkiness disappeared 

 from the water. The washed residue was then dried in a 

 shallow vessel, the organisms picked out with a fine sable-brush, 

 and mounted in the usual way. Turpentine or carbolic acid was 

 often useful in rendering chalk forams transparent, when they 

 were to be mounted in Canada balsam ; but these sihcious speci- 

 mens would be spoilt if either turpentine or balsam were used. 



March lAth. — " Helix aspersa, considered as a type of the Land 

 Gasteropods," by Mr. Kenneth McKean, F.L.S. 



April llt/i. — The evening was devoted to an exhibition of 

 microscopes, and other scientific apparatus and objects, in the 

 Small Public Hall, by the Microscopical Sub-Committee, after the 

 transaction of the ordinary business. There were 19 exhibitors. 

 No paper was read.
