it_o that_o if_o you_o project_v a_o ball_n from_o the_o poop_n to_o the_o before_o castle_n of_o a_o ship_n under_o sail_n and_o back_o again_o from_o the_o forecastle_a to_o the_o poop_n you_o

former_a case_n the_o force_n or_o second_v impulse_n of_o the_o ship_n must_v be_v superad_v to_o the_o force_n of_o your_o arm_n in_o projection_n and_o so_o make_v it_o the_o strong_a and_o in_o the_o latter_a case_n the_o contrary_a force_n of_o the_o ship_n do_v as_o much_o detract_v from_o the_o force_n of_o your_o arm_n and_o so_o make_v it_o the_o weak_a and_o though_o the_o ball_n be_v
