16 ILLINOIS ACADEMY OF SCIENCE 
tollows: Article II] was amended (1) by striking out the 
words “corresponding members’ and “honorary members” 
from the first paragraph, and by inserting the word “‘and” be- 
fore the words “‘life members,” and, (2) by striking out para- 
graphs 4 and 6, relating to corresponding members and hon- 
orary members. 
On motion, the Council of the Academy was instructed to 
prepare a codification of the Constitution and By-Laws of the 
Academy so as to make them harmonize with the various 
amendments, resolutions and practices adopted by the Academy 
at different times, and to report the same to the members in 
time for action at the next annual meeting. 
On motion, the Treasurer was instructed to invite fifty 
or more members to pay dues sufficient to make them life 
members. This measure was prompted by the need of funds 
to enable the Academy to catch up with the publication of its 
transactions. On August 20, 1917, twelve members had re- 
sponded to this call. 
On motion, the President and Council were instructed to re- 
organize the committee of Secondary School Science, and to 
consider with the committee the recommendation made by the 
Secretary in his report that some kind of “junior membership” 
be planned for students in high schools and colleges, and if 
such a plan can be worked out, to report at the next annual 
meeting. 
Following this business session, a session was held at which 
a number of papers of a general nature were presented. All 
of these papers are printed in this volume under the head of 
“General Papers.”’ 
TENTH ANNIVERSARY SESSION 
At 6 o’clock on Friday evening, about 150 members and 
friends of the Academy assembled at the Galesburg Club for 
dinner and for an elaborate program of addresses by delegates 
from other academies of science and from scientific organiza- 
tions within the State. This program was planned and ar- 
ranged entirely by President Trelease and much credit is due 
him for its eminent success. The program was arranged in 
honor of the tenth anniversary of the founding of the Acad- 
emy.
