FOOD and LIQUOR ADULTERATIOHS
Discussion on the Report on
Insectides. -
OTHER TOPICS DISCUSSED

An increased attendance marked today's
meeting of the eighteenth annual conven-
ton of the Association of Official Agricul-
tural Chemists now in progress in the Co
lumbar University. None of the papers read
excited vigorous discussion. The conven-
ton proceeded so rapidly with its labors
that II is possible 1t may conclude its work
this afternoon.
Reports were read during the morning
session on liquor and food adulteration. nj
trogen insecticides. cider fermentation and
dairy products.
The first subject considered-liquor and
food adulteration-came before the conven-
ton in a report from Delegate Bigelow. \
symposium of comment on the different
methods of food examination was present
ed, which included expressions of opinion
from thirteen investigators. From the
study of all those reports, Delegate Bigelow
recommended the appointment of a ref
cree on the general subject of food adulter-
alton, that the methods of investigation be
slightly revised and that the reports of the
thirteen investigators be printed for the
information of the delegates.
Delegate Perkins offered a report on
nitrogen. IN which he gave the results OF
certain tests conducted in the permanganate
method of nitrate determination. to the
effect that the results obtained all indicated
more nitrogen than really existed.
Cider Fermentation.
The report on cider, fermentation submit
ted by Delegate Atwood, concerned an at
tempt made to control lamentations so as
to produce definite results.
A long discussion was provoked by the
report on insecticides. Delegate Voorhees,, in
the course of that report, recommended that
the prevailing methods of determining the
presence of formaldehyde in compounds
should be continued. This led to some de-
bate on the use of paris green in
secticide, the possible injury done to plants
by paris green in solution and the effect of
lime as preventive of injury TO plants
through the use of paris green 1t was
finally agreed that lime lessened the injury
occasioned by the presence of paris green
In solution. but did not altogether prevent

ter The discussion of the first subject
was wholly technical 1t was stated con-
corning the renovated butter sometimes
offered for sale that while many chemical
tests were found to be efficacious the best
means of determining whether not but

heat the butter to a boiling point. Reno
waited butter, according to the report, will
"sputter." and fresh butter will merely
foam.
Various amendments to the constitution
