stand, which was approved by tlic Oommittco, but it was suggested 
that bottles should bo used instead of zinc. Mr. Hobs, gardener 
to C. Eyre, Esq., took the First Prize for Apples, Mr. Miles and 
Mr. Parsons also obtaining Prizes. Mr. lioss was the only ex- 
hibitor for Snow's Winter White Brocoli. 
SCIENTIFIC COMMITTEE. 
The Secretary brought a portion of a small branch of a Cedar 
the upper end of which had perished, though much larger in dia- 
meter than the part beneath it which had been injured by the 
frost of 1866 ; it illustrated the fact that the injury induced by frost 
is frequently not fully apparent till after the lapse of some years. 
A plant of Iresme Berhstii was sent from the Society's garden 
at Chiswick, in which half of the whole plant was green while 
the other half was red. 
Prof. Thiselton Dyer pointed out that the bright pink bracts 
of Dalechampia Roezliana acquire a green colour as the fruit is 
developed. 
GENEEAL MEETING. 
J. Bateman, Esq., F.R S., in the Chair. 
Attention was again called to Toxicophlcea , which scarcely 
differs from Carissa, and to the curious Azalea linearis sent by 
Messrs. Standish. Prof. Thiselton Dyer then commented on 
General Pleasonton's theory respecting the effect of coloured 
glass on the growth of Vines. Violet light was anything but 
advantageous for two of the things which were most essential to the 
growth of plants — the formation of chlorophyl and the evolution 
of oxygen from the leaves. He could not, therefore, encourage the 
adoption of this system. Mr. Bateman then observed that care 
should be taken in staging Orchids that their tints were not over- 
whelmed by the primary colours of Hyacinths and Tulips.
