of water, acting like burning lenses, or possibly by chilling the 
tissues. 
The Chairman expressed his opinion that the holes in question 
were produced by insect-puncture (Thrips ?), and a consequent un- 
equal contraction of the tissues of the leaf, ultimately resulting in 
the death of a circular portion of the leaf, and by its falling out 
leaving a hole as if punched out. 
The Chairman also showed a remarkable dwarf variety of 
(Jupressus macrocarpa, about 4 inches high, and as many through. 
The plant, which was nine years old, had been obtained from seed 
by Messrs. Garraway, of Bristol. Some doubt was expressed as to 
its belonging to C. macrocarpa at all ; in any case it is a very remark- 
able plant, analogous in habit to the Clanbrasilian Fir. 
The Chairman also exhibited bulbs of Amaryllis in a dr^cayed 
state, and partially eaten by the larva of a Dipterous insect, JEristalis 
intricarius, which it is surmised might have been introduced with 
liquid manure. 
Mr. Miers exhibited specimens of a new and apparently valuable 
fibre, obtained from a Brazilian climbing plant with opposite leaves. 
The fibre appeared so abundant and so good that further particulars 
were requested. 
Prof. Thiselton Dyer communicated an additional note with 
respect to Honey-Dew (Journ. IN". S., vol. iv., pp. 6-7). 
GENERAL MEETING. 
James Bateman, Esq., E.E.S., in the Chair. 
Mr. Marshall spoke very highly of Mr. Peacock's collection of 
succulent plants as most worthy of inspection. 
In allusion to the poisoning of a clergyman in Norfolk by sus- 
picious Mushrooms, Mr. Berkeley advised amateurs to exercise very 
great caution before they ate doubtful kinds. 
Mr. Barr's splendid double Narcissi were obtained by deferring 
the planting of the bulbs till January. 
Prof. Thiselton Dyer called attention to the traces of tints con- 
colorous with those of the flowers in the foliage of Cinerarias. This 
was a matter of some theoretic interest, because it seemed to show that 
the colours of flowers were produced by a process possibly of oxida- 
tion from elaborated matters, such as already existed in the foliage. 
It was known that, while deoxidation took place in the leaves, oxida-
