tion or rotation of the cell contents, a state of things admirably seen 
also in the rootlets of the frog-bit, Hydrocharis morsus-rane, and sug- 
gested, as the Society, on the occasion of its annual excursion, next 
Friday, to Arundel, would be in a district especially rich in pond life, 
that, if the next meeting were on that subject, many interesting things 
might be obtained for exhibition. 
Mr. Wonror considered the suggestion a very good one, because, 
in addition to Arundel, they would, before their next Microscopical 
meeting, visit Plumpton, a locality very fertile in pond life. 
The meeting afterwards became a Conversazione, when 
Mr. Henan exhibited the specimens sent by Mr. Curties, the 
most noticeable among which were hairs of different species of 
Alyssum, Tillandsia, Zonata, Loasa, onosma taurica, and sections of 
stems of different solanums, dc. 
Mr. R. Guatsyer exhibited some very beautiful scales of different 
ferns in situ and as transparent objects, and the siliceous scales of 
Deutzia scabra and gracilis. 
Mr. Wonror exhibited various scales and hairs, chiefly of a 
stellate character, some of which, from different ferns, such as the 
Niphobolus hastatus and Lingua, the stagshorn Acrostichum Alcicorne 
and Rhododendron ferruginum, were much admired, as were also some 
of the same scales seen under polarized light. Later in the evening 
he showed the circulation of the cell contents in the beaded hairs on 
the stamens of Tradescantia, the blue spider wort, and eggs of Sialis 
lutuarius, obtained on the occasion of the Field Excursion to 
Barcombe.
