Bulletin of the Scientific Laeoratories of Denison Univer- 

 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 

 generous 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.
