Portland cement being taken as stand
ard. The tests were for fineness, tensile
strength, compressive strength and trans
verse strength. The results were embod-
led in five tables and a chart. The test
for flneness showed that 27.3 per cent. OF
the Kansas City cement, 2S.5 per cent. of
the New York cement and as per cent. Of
the Portland cement did not pass through
the standard seive, 1880 meshes TO the
square inch. Teusii tests were made on
neat cement and sand mixed in various
portions. The specimens taken varied IN
age from one day to twenty-three days.
The tensil strength at the end OF twenty
days, is: Kansas City cement. 80 pounds,
Fort Scott, So pounds and Portland 80
pounds. The compressive strength at the
end of twenty days. is: Kansas City ce-
ment, go pounds. Fort Scott, $50 and Port
land l,90S pounds. Statistics, in regard 10
capacity of works, number and kind OF
kilns, number of brushes and cost of ce-
ments were given. Prof. L. G. Blake, of
the State university read paper on Some
tests On insulation resistance of electric
light wires exposed to moisture"
Tests were made in the Plugrical labora-
tory of the State university upon six of
the best known arc light wires in the mar
ket. These were immersed in water for
three months AID daily tests upon their
insulating power made. From the guar
autees of the makers, their wires should
| have shown a resistance Of several million
ohms per mile. Electrically a good insu-
lation should keep the current in the wire,
| and mechanically should resist abrasion.
heat and moisture. We know little yet of
| the effect of several years exposure OF
wires and hardly anything about the long
continued influence of alternating cur
rents. Probably the brittleness and ten
sle strength will be altered in time by
such currents. After describing the deli
cate methods of the testing, the results
were shown by a series of curves showing
the variations in ohms as the time of ex-
posure increased. With one exception
none of the wires gave over 5000 ohms per
yard where millions were guaranteed. The
dangers of fire and of grounding arma-
lures were shown. The best wlre-Oko-
nite-gave over 500, 600 ohms per yard. All
the wires were taken from electric light
circuits and the tests were made for an
electric light company.

sent to the academy by Prof. Fellows, of
Tongonoxie, entitled Autumn Leaves"
| Seargent Jennings, of Topeka, read
paper written by Geo. E. Curtis on an ex-
animation of the value of Blake's tables of
weather prediction for 80. He proceeded
to give data showing where the tables did
not correspond with the facts and con-
cludes his effort for 80 at making a wealth
er table scarcely worthy of confidence.
Prof. W. L. franklin presented paper
through Prof Blake upon classification of
the sense of smell.
The quality of different sensations of
smell must depend upon the action of spe-
cific nerves. Are there then few specific
nerve groups or large number of nearly
| independent groups? The sensations of
smell must form discrete manifoldness,
and hence there can be no such systematic
arrangement of smell sensations as there
is of colors. The sensations of smell are
of an essentially discontinuous nature and
therefore are of as many elements as there
are specific groups of olfactory nerves.
EVENING SESSION.
Promptly at s o'clock President Dins-
more called the meeting to order and stat
ed that the Garfield university had extend

session at the university. A motion was
made to accept the invitation and hold the
forenoon session at Garfield which carried
without opposition.
The Rev. J. ID. Hewitt delivered an ad
dress of welcome. He said it give him
great pleasure to welcome such a body of
scientists to the city. They should re-

city of Wichita appreciated the presence
