tliat of ordinary brick walls. The woodcuts will give an idea of their fairy-like 
elegance. They are the invention of Mr. Beard, of the Victoria Works, Bury 
St. Edmund’s, the patentee and manufacturer, from whom particulars, or the 
walls complete and ready for use, may be obtained. This gentleman rendered 
good service to horticulture by the abolition of putty and other sticky modes of 
glazing, but I believe these glass walls will prove a greater boon. They save 
space, guard against extremes of temperature, double our extent of genial surface, 
give us the command of every possible aspect by adopting the zig-zag form, and 
are strong, cheap, clean, and durable.—D. T. Fish, F.R.H.S.

^|HE event of the month—horticulturally speaking—has been the Roifal 
Horticultural Society's Great Show at Oxford. This, as an exhibition, 
has been one of a most satisfactory character ; but from the greater 
attractions of the neighbouring Agricultural Show, and the scanty popula¬ 
tion of the district, the flower show fell short as to the attendance of visitors, and consequently 
as to the returns. At the congress meetings some very interesting papers were read. The 
Rose shows held towards the end of June were remarkably good, notwithstanding the drought 
of the season. The variety which seemed to he in the ascendant this year was Alfred Colomb. 
-- ^ VERY interesting collection of Mimetic Plants was exhibited at a 
recent soiree of the Linnaean Society by Mr. Wilson Saunders. The following is 
a hst of the mimetic pairs. The plants were none of them grown for the pur¬

- Deherain has recently 
Sciences a note on the Decomposition of Carhonic Acid by the Leaves of Plants^ 
under the influence of light. The same decomposing faculty had been attri¬ 
buted by some observers to all the luminous rays of equal intensity, while others had affinned 
that more oxygen was disengaged from plants lighted by yellow and red rays, than by those 
which were lighted by blue or gi-oen. In former researches, M. Dehbrain had demonstrated 
that evaporation was more active in plants exposed to yellow and red lights than in those 
exposed to green and blue. This coincidence he regarded as establishing a connection between 
the two vital functions of the loaves,—the evaporation of water, and the decomposition of 
carbonic acid by the disengagement of oxygen.
