Quarterly Report of the Chemical Committee. 847 
Treatment advised is reported as not having succeeded ; and in these 
;ases I have had reason almost invariably to doubt whether the 
directions were thoroughly carried out. 
But with regard to the more general spread of information, which 
is still much needed, I do not see how to meet the point excepting 
by the subject being taken amongst the short familiar lessons in 
country schools. 
Frequent application is made to me both by agriculturists and 
agricultural teachers as to how they may best respectively procure 
and impart serviceable information on the subject of farm pests. 
In the past year the number of letters which I have written in 
reply to requests for identification of insects, or on points imme- 
diately connected, practically or theoretically, with injurious insect 
prevention has been approximately 900. This is somewhat less than 
in the previous year, but I do not include, in the above, attention to 
over 150 applications regarding warble matters, nor replies to minor 
matters of prevention which could be as serviceably given under my 
direction as written in full by myself. In all cases I have given the 
most careful personal attention to inquiries from members of the 
Society. 
Colonial Inquiries. 
Besides attention to home inquiries, I have also been in communi- 
cation regarding various Colonial attacks. Amongst these I may 
especially mention procuring, at request of the Professor of Agriculture 
at Cairo, identification of moth caterpillars destructive to cotton in 
Egypt, and directing him to means found serviceable for the preven- 
tion of this kind of attack in America : also, at the request of the 
Agent-General for New Zealand, assisting him in gaining the most 
trustworthy information as to treatment suitable for checking 
spread of phylloxera in that Colony. For this we are indebted to 
courteous and prompt attention from Professor Riley, the State 
Entomologist of the United States, the best authority on the subject, 
and I am personally also much indebted to help in cases of especial 
difficulty to the Dominion Entomologist of Canada, and leading 
entomologists, both European and American.

QUARTERLY REPORT OF THE CHEMICAL 
COMMITTEE. 
December 1890. 
1 and 2. Mr. D. Burnett, of Stockbridge, sent for analysis on 
August 28, 1890, two samples, one of linseed and one of cotton-cake. 
Both cakes were bought as pure, the price of the linseed being 
81. 10s. per ton, delivered, and the cotton-cake 5^. 10s. The follow- 
ing analyses and reports were returned on September 9, 1890 : —
