SCIENCE ASSOCIATION.

Boston, Aug. 31.-The American
Science Association met again in
general session this morning for the
transaction of general business. The
first business was the election of Off
GERS for the meeting of 1881, and
the following were chosen: Presi-
dent, Prof G.. S. Brush, of New Ha-
ven; secretary, Prof. @. V. Riley, of
Washington; Treasurer, Prof W.
S. Vaux, of Philadelphia. President
of section a. Prof A. Mayer, of Ho-
boken, N. j.; secretary of section b.,
Prof. VIM. Saunders, of Canada. Au-
ditory Committee, Prof. Henry
Wheatland, of Salem, and Prof.
Thos. Mechan, of Philadelphia. A
resolution providing for social reu-
Mon of the sections on the second
evening of the future meeting
was adopted and also one
recognizing the services of the
late Gen. Myer, of the sig
nal service. Another resolution
was adopted providing for the ap-
pointment of a committee to select
a series of stars of stellar magnitude
for standards, to be reported at the
next meeting.
In the department of physics pa
pers were read as follows 'Upon
the use of mercurial thermometers
at high temperatures" by Prof. Silas
W. Holman; ION the movements of
physical constants" by Prof. Alfred
M. Mayer. Remarks were also made
on Mr.. G. S. Pierces paper on
Ghosts in Rutherford's gratings." p"
In the chemical section, Prof. A. A
Breneman, o: Cornell, exhibits the
results of experiments to obtain
new colors for common gray stone
ware, now decorated only in blue.
The samples exhibited showed that
the range of colo-s which can be OBJ
tanned fof ware is very great. A vase
was shown upon which vine in
green was painted upon the ordinary
gray body of stone ware. This cheap
ware may in this wey be made the
basis of new process of underglaze
decoration in which the piece. color,
glaze and body is colored at a single
burning. The theory of the new
process rests upon the thickr ess and
comparative impfessibility of the
glaze.
Prof. Riley, of Washington, read
an interesting paper on the recent
practical results of the cotton worm
inquiry by the United States ento
mological commission. He stated that
the cotton worm of the south is &
small looping caterpillar, the larvf
O. moth known to science as aletis
a-gillecca While there are many
other insects injuriously affecting
the cotton plant, these is the worst
OF all, and careful statistics show
that the people of the south have
suffer cd an annual loss since the wal
of about $l5,000,000 from it's raw
ages. sa a,.sas.H .
Mr.. E. B. Elliott, of Washington
read paper. on the electric lighting
as applied to large areas. He insti
tuted comparison between the rela
tive cost of the lighting of larg
areas by Illuminating gas and b.
electric pro,e~ es, deciding in ia
vor of the lar1er. He then com
pared the relative efficiency O
several processes of electric lighting
showing the greater eco lomy of tn
process known as the electric arc
over the ''incandescent, so-called, ,ant
over the combination of the tw,
known as the candles of Jabloch-
kof and off wild, the " electric arc
process being in the lighting of larg
areas by far the most economical
and its success for this purpose i
now beyond question.
