The Eev. T. E, E. Stebbing, F.E.S., Sec.L.S., exhibited:—
(1) a House-spider {Te(jenana sp.) with its cylindrical dwelling
in the coiled feather of an Indian fan. The fan which the spider
adapted to its purposes had been hanging up in a drawing-room at
Jerusalem. The spider, forwarded by Miss Eitzjohn to Miss Grace
Stebbing, reached England alive. And (2) a solid gnaur or
excrescence upon the root of Cvpressus macrocarpa^ sent for
exhibition by Mr. E. G. Smart, E.L.S., of Tunbridge Wells; it
was eleven inches in circumference.
Prof. Peec'IVal remarked that such growths were commonly
due to the attack of a Uredine fungus, which resulted in an
hypertrophy of the tissues ; it was not infrequent in Piiius, but
more usual on the stem than the root.
A lantern demonstration was given by Prof. J. Bretland
Earmee, E.E.S., F.Z.S., entitled " A brief Account of New Eesearches
in Cancer," in which he alluded to current theories of
cancerous growth, and then proceeded to state his own discovery
that the cytological changes in malignant growth resemble those
exhibited by sporogenous or gametogenous tissues in plants and
animals, in the occurrence of the form of nuclear division know
as heterotype, as distinguished from the more usual homotype
division.
