an elephant’s tusk—probably a mammoth’s—and a number of 
horses’ bones. An interesting discussion ensued, in which 
several members took part. 
This ends my record of events; the several Sub-Committees 
must now speak for themselves. 
BoranicaL SuB-CoMMITTEE. 
I have no report to make this year of any official proceedings on 
their part. 
It is, however, worth recording that the rare Carex strigosa was 
found in considerable abundance on the occasion of the Whit-Monday 
excursion in the neighbourhood of West Hoathly. This plant is 
specially a Sussex plant, and has only once been recorded from Surrey. 
The rarest of our local plants—Teucriwm botrys—has been in great 
abundance this year in its locality near Addington, and, we are glad 
to know, has reappeared in considerable abundance this year in its 
only other British locality at Box Hill, where it had of late years been 
apparently dying out.—Signed, H. T. MEnNnELL. 
GEOLOGICAL SuB-COMMITTEE. 
The only matters calling for notice in connection with the Geo- 
logical Sub-Committee are the fresh discoveries of mammalian remains 
in the gravels round Croydon, and more particularly that of the 
rhinoceros’ skull found at Carshalton, and described to the Club by 
Mr. EH. T. Newton, F.R.S., and Mr. W. Whitaker, F.R.S.; and the 
flow of the Bourne in the Caterham Valley during the months of 
March, April, and May, 1897. Unfortunately I have no record of its 
first appearance, but during March the stream gradually worked its 
way down the valley, and on the 26th it passed through the culvert 
beneath the railway embankment at Purley Station. The surface flow 
continued without any noticeable diminution of volume to about the 
10th April, when it reached the junction of the Godstone and Brighton 
Roads, and did not apparently extend beyond this point nearer Croydon. 
On May 7th the stream no longer flowed through the railway culvert 
at Purley; on the 16th there was still a fairly strong current in the 
valley opposite Little Roke; but on the 23rd the channel was quite 
dried up throughout. 
Should any of our members be able to furnish any details of the 
volume of water or other particulars of this Bourne outflow, it would 
be very desirable to have them recorded in our ‘Transactions.’—

MicroscopicaL Sus-CoMMITTEE. 
The Microscopical Sub-Committee held one Conversational Meeting 
during the year, which was fairly well attended. Vegetable anatomy 
was the subject for discussion, and numerous slides illustrating various 
structures were exhibited by the Honorary Secretary of the Section. 
Members are reminded that there is a large number of microscopical 
slides in the Club cabinet which can be borrowed under the same 
regulations as books from the library, and the Club microscope is also 
available for exhibiting eit at any of ea aennes: —Signed, W. 
Murton Houmes.
