The slight expense connected with membership of the 

 Ohio Academy of Science, the vakie of the Annual Reports, 

 and the many advantages to be derived by joining these ex- 

 cursions, etc., should indvtce the teachers of the state to 

 accept the invitation to join the organization, which is open 

 to all who are interested in any branch of science, or who 

 desire to assist either in developing or diffusing knowledge.
