AORICULTCRAL CHEMISTRY ASSOCIATION. A
general meeting of the subscriber* of this society was held
yesterday at the Thatched House Tay. rn, St. James's
-street-
In the absence of Lord Portman, who was prevented by
illness from attending, the Duke of Manchester was voted to
the chair. The Rev. A. 11u:table, the hon. secretary. ex-
plained that this association had been stablithed to supply
a want which had been long felt by those who were interested
in the improvement of agriculture, some national lab sratory
or establishment wherein analyses of soils, manures, and vege.
table products might loe c ,cried on. In Scotland a similar
insti-
t lion had existed since 1842, and with the best results. Guano
arid other manures, especially foreign snanur a, were much ex-
posed to adulteration ; and unless means were found foranalys-
ing such substances, and ascertaining t sir chemical proper-
ties and consequent value at a mod rate cost, it would be
impossible fir the farmer to purchase or apply them to
his land with any a rtainty. One sample of guano
sent to Professor May, the analytical chemist of the associa-
tion, was found to contain 19 per e, nt of water; the average
being 10 or 11 per cent : and the party who was about to
m. ke the pt.ri hue obtained a reduction in the 'nice of the
guano equal to the deterioration, ni between 8 and 10 per
cent. The fee for these analyses was about 31. or 41., though
many of them cost the professor as much as 81. or 91. Al
the responsibility incurred by the subscriber, was the 2/. or
3/. a year they subscribed; Professor May,on the faith of those
subscriptions, undertaking all that was necessary. Having
mentioned several instances of practical bens fit resulting from
the professor's anslyscs of soils and menures the advantage iu
one instance having been derived by Sir R. P. el, who had sent
samples of the soul of three of has f .rms fur examination;
the rev. secretary observed that the papers puldisticd by Mr.
Laws in the Journal of the Agricultural Society, stated that
nitrogen, in the shape of ammonis a d phi sphoric acid, but
principally the former. was the grand ri guirera. nt for grow-
ing wheat; and if they could obtain a sheep supply of
ammonia they o'ituined a cheap supply of bread. (Ilea.)
The grand source of this agent was decay. danimal and vege-
table products ; and in many parts of Ruglaiol, especially
those near the coast, animal substances were occasionally to
be ban In attendance. On the property of Mr. Matthison be
was told there had been recently a large catch of
whales these, wl.en the oil was extracted, were
taken out into deep water and sunk, but if means
were talon to obtain from them the ammonia, they
might obtain for 21d. a pound that which now cost Ba. or
9d. Having explained various interes'ing experiments made
by the professor an to preserving the leaves of turnips,
mangel warmth, and other roots, fur the foo-I of cattle, sheep,
&e., and of restoring O.: nitrogen drawn from the land by
exhausting crops, such as Italian rye grass, the rev. gentle-
man concluded by calling on the agricultarists generally to
support an institution c ilculated to c infer so much
beneht. R.:solutions in Import of the society, and for ap-
poin ring the committee and tither officers Inc t .e ensuing year,
were moved and sp ,ken to by Mr. It. Denison, M.P.,
Lord Burlington, Mr. Bane, Mr. R'hi,more, Mr. F. Hobbs,
Sir J. V. Johnstone, Id I'., Mr. Holland, Lord St. John,
and Mr. Shaw' in the c tune of which many instants of the
advantages which had followed from the analyses of the pro.
f. asor were mentioned, and a wishi was generally expreiped
that ere long the English Agricultural Society would follow
the example of the Highland Agreultural Society, and
unite the Agricultural Chemical Association with them.
Thanks were then voted to the chairman, and, having been
acknowledged, the meeting separated.
