Zambra, and supplied at a moderate cost, eacii instrument having 
been tested by Mr. Glaisher. No instrument will be passed which 
shall be in' error more than y\j of a degree. A very excellent mo- 
dification of the thermometer for ascertaining the temperature of 
roots was exhibited, which was highly approved. 
Mr. A. Murray showed sj)ecimens of an insect from Port Philip 
which is destructive to oats, being scarcely distinguishable, without 
close examination, from the oats themselves. He also brought 
specimens of the Tsetze, or African fly. 
GENEEAL MEETINQ. 
W. A¥"iLS05^ SArNDERS, Esq., E.E.S., in the Chair. 
In the absence of Mr. Bateman, Mr. Berkeley stated tbat Onci- 
dium splendidum, Stenia ^mhriata, from Lord Londesborough, and 
Vanda ecBrulescens, from Messrs. Yeitch, were exhibited for the 
first time. The latter was described by Dr. Lindley thirty years ago, 
but had only recently been introduced into this country. Goodyera 
Daivsoniana was then pointed out, as, though extremely beautiful 
in foliage, it does not require the same close treatment as many 
of the allied Orchids. A Primula sinensis with white and rose- 
coloured flowers in the same truss was then pointed out, atten- 
tion being drawn to the fact that the side of the plant which 
bore the white flowers had leaves with pale petioles. 
Mr. Berkeley then made some observations on the insect which 
is at the present time so destructive to Yines, calling especial at- 
tention of cultivators to the circumstance that winged individuals, 
probably males, had been figured by Planchon. The galls con- 
taining the insects on the leaves sbould at once be burned, and 
gas -water has been recommended as a remedy, but must be 
used carefully. 
Forty Essays were on the table in competition for Mr. Hub- 
bard's prizes. 
Mr. A. Murray made some observations on dcpressics Lawso- 
niana as more hardy than C. Qnacrocarpa, W'hich had perished in 
the neighbourhood of London. 
Mr. Berkeley stated, however, that though almost every plant 
was killed in the valley of the Thames, it did not sufl"er in Hun- 
tingdonshire and Northamptonshire.
