Bulletin of the Scientific Laboratories of Denison 
siTY, Granville, Ohio. 
EDITORIAL STATEMENT. 
Every well conducted institution of learning should form a recog- 
nized centre of scientific activity ; and legitimately concerns itself, not 
only with the instruction of those who directly entrust themselves to 
its charge, but with the dissemination and conservation of information 
relating to the subjects taught. Moreover, in connection with the 
laboratory drill, it often happens that facts of general scientific interest 
are brought to light which the student may be ill prepared to appreciate 
in all their bearings. Such facts, if preserved, may, at another time, 
become very valuable, while, if not thus preserved, they would be lost. 
Still again, instructors will, as a rule, be unable to instill enthusiasm if 
they themselves do not come in contact with nature at first hands, 
while the fragments of time, which are often frittered away, can be 
made most useful to themselves and others by being applied to studies 
in advance of the work required by the curriculum. 
The present publication, which we are able to present through the 
genenous co-operation of numerous friends, is a step toward filling a 
need hinted at in the above paragraph. The bulletin is intended to 
represent the life of the college in its scientific departments and may 
incidentally serve to illustrate to distant friends the facilities for work 
afforded, as well as needs still unsupplied. To the scientific students of 
the country we confidently appeal for support and indulgence, since it 
is hoped to devote an increasingly large portion of space in each number 
to technical papers which have more interest to the student than to the 
general public. To the teacher, with still greater confidence, we look 
for encouragement, as it is entirely in the interest of better school work 
that this bulletin is prepared. While limited means has, in this first 
number, prevented the use of costly illustrations, it is hoped that the 
generous patronage of this volume will enable us to extend to the con- 
tributors to the following one more elegant, if not more perspicuous 
graphic aids.
