A. Because the human body is a

 ductors for its path, it would (in this case) 

 pass through the man, and injure him. 



Q. Why is it DANGEROUS to BAR a SHUTTER 

 during a thunder-storm ? 



A. The iron shutter-bar is an excel- 

 lent conductor ; and (if a person were 

 touching the bar), the electric fluid

 through the person touching it, and 

 injure him.

Q. Why is a MASS of bodies a better con-
