Mr. Dowker.—Water lily intercellular spaces (Polar), sections, of 
elevated ridges in front of leaf, feather grass ; of Psamma arenaria, 
of Phalaris arundinacea, of stem of Ribes nigrum, of horn of 
African Rhinoceros, Drosera rotundifolia and Anglica. 
Original impressions of the nature-printed Ferns, which were 
printed by Bradbury Evans, were exhibited by Mr. W. E. Goulden ; 
and Mr. 8. Harvey gave a description of the method of printing 
them from the direct impression of them taken upon copper sheets. 
XXVIII.—Summer Excursions and their Results. 
The Society this Summer continued the more general excur- 
sions of its members that were resumed in 1885, after a lapse of 
several years, during which period limited excursions of a few 
members only had been made in the immediate neighbourhood of 
Canterbury. It has been considered advisable to put together 
under one head some of the chief and more interesting results and 
observations arising from these meetings. June 16th, 1887.— 
Excursion was made to Kastwell Park and neighbourhood, under 
Mr. H. Dean’s guidance. A thorough observation of the plants in 
flower at the time, chiefly in the direction of the Wye Downs, was 
made, and a list subsequently drawn up by Mr. J. Fielding, and 
added to the Registry of the Society. The spring season having 
been much delayed, many of the earlier and other spring flowers 
were blooming with the later ones, and even the summer series; 
crategus oxycantha was seen in full blossom with Sambucus nigra. 
July 6th.—The excursion, mainly botanical, was to the Sandhills, 
near Sandwich, and thence to Deal. The plants observed were 
chiefly aquatic in the bordering dykes. Zypha augustifolia was an 
object of marked interest. The plant was in a condition of early 
inflorescence ; the light grey tips of the styles bedecked the dark 
downy mass of the lower part or female portion of the spike, 
whilst the upper separate portion with the male blossom was of a 
dull sulphur colour from the anther valves charged with pollen. 
It needed only a tap or vibration of the stem to cause a cloud of 
the yellow pollen to be set loose and be wafted by the breeze over 
the dyke. Convolvulus soldanella, orobanche caryophyllacea, and 
hottonia palustris, flowers of the district were noticed, but were 
passing off. A Dredging Excursion was made in August at 
Whitstable, under the direction of Mr. 8. Saunders. Sept. 21st. 
The last excursion was made to view some new geological features 
that had been revealed in the lower strata of the chalk in the deep 
railway cutting at Etching Hill, recently made for the Elham 
Valley Railway. Mr. G. Dowker, F.G.S., who had first noticed 
the peculiarity, demonstrated the section to the party from a point 
of vantage above the tunnel. An apparent absence of the lowest 
beds as known in the district, together with several extraordinary
