ing been exhausted, and there being 
already a considerable number of 
applications from members for copies, 
which could not be complied with. 
The Committee suggested that oppor- 
tunity be taken of printing in this 
list a statement of the Presidents, 
Trustees, Vice-Presidents, and Mem- 
bers of Council of the Society since its 
establishment. 
Combination Picture of the Council. 
Sir Nigel Kingscote remarked 
that the Combination Picture of the 
Council and Officers of the Society at 
the Windsor Show of 1889, which 
included portraits of Her Majesty the 
Queen and the Prince of Wales, was 
now completed, and copies would be 
available immediately on application 
to the photographer, Mr. Barraud, of 
263 Oxford Street. The ordinary 
size of the picture would cost a 
guinea, or, framed, 11. 15s. ; but a 
larger size would also be published, 
the price of which would be five 
guineas. 
Journal. 
Earl Cathcaet (Chairman) re- 
ported that the Editor had submitted 
a list of the proposed articles and 
notes for the forthcoming number of 
the Journal, which had been approved. 
Mr. Whitehead's revised edition of 
his pamphlet, Hints on Vegetable and 
Fruit Growing, had now been issued 
from the press as a sixpenny pam- 
phlet. The purchase for the library 
of Messrs. Macmillan's new Library 
Keference Atlas of the World had 
been authorised. Various suggestions 
for articles in future numbers of the 
Journal had been considered, and 
directions thereon given to the Editor. 
Chemical. 
Viscount Emltx (Chairman) pre- 
sented the report of the Committee, 
which included details of the experi- 
ments on the feeding of bullocks and 
sheep at Woburn, and on the sale of 
the animals. These results will be pub- 
lished in the Journal [see page 399]. 
Seeds and Plant Diseases. 
Mr. Whitehead (Chairman) pre- 
sented a report by Miss Ormerod, the 
Society's Consulting Entomologist 
[which is embodied in the paper pub- 
lished on page 407.] 
Mr. Whitehead, in reference to 
Miss Ormerod's very interesting re- 
port, containing an account of the 
caterpillars which were now devas- 
tating the fruit-trees of this country, 
said it was very difficult to find effec- 
tual remedies against these pests. 
The Agricultural Department in Ame- 
rica, where these caterpillars were 
very troublesome, recommended the 
use of arsenite of copper. Miss 
Ormerod reported that the Experi- 
ment Committee, lately formed at 
Evesham, had decided to recommend 
the use of this arsenical poison in the 
form of Paris green or London purple. 
Under the supervision of that Com- 
mittee these two deadly poisons had 
been tried on fruit-trees with, so far, 
signally good effect. Of course it 
was highly dangerous for the poisons 
to be scattered broadcast all over the 
country, and one could not advise too 
much caution in their use. With re- 
gard to the Paris green, the propor- 
tion which should be used was one 
ounce of the poison to twenty gallons 
of water for apple-trees, and one ounce 
to eight or ten gallons of water for 
plum-trees. One pound was supposed 
to be enough for from 140 to 280 
gallons of water. Experiments had 
been made with London purple in the 
fruit plantations of Kent. In one 
instance the solution had been too 
strong, and it had not only killed the 
caterpillars, but had scorched up the 
trees. This showed how very careful 
they should be. At the same time a 
fair and proper trial of these poisons 
might avert a plague of caterpillars. 
They had had for the last three years 
caterpillars innumerable, and if not 
checked by some means they would 
have a very disastrous effect. 
Mr. Hamond having raised the 
question of the effect of the poisons 
upon the birds which live upon the 
caterpillars, and the Earl of Ravens- 
worth of their employment upon 
trees under which animals might be 
feeding, 
Mr. Whitehead replied that with 
regard to the birds the caterpillars 
were so very small and so embedded 
that the birds were hardly able to get 
at them. There was not the least 
danger of the birds being affected in 
that way, at all events in the early 
stages. With regard to the question
