of_o pulsion_n yet_o both_o of_o they_o to_o i_o seem_v to_o be_v but_o extrinsical_a denomination_n of_o the_o same_o local_a motion_n in_o which_o if_o a_o body_n move_v precede_v the_o movent_fw-la or_o tend_v to_o acquire_v a_o great_a distance_n from_o it_o we_o call_v it_o pulsion_n and_o if_o upon_o the_o account_n of_o motion_n the_o same_o body_n either_o follow_v or_o tend_v towards_o

that_o enable_v it_o to_o drag_v that_o body_n after_o it_o so_o that_o attraction_n evident_o appear_v to_o be_v a_o species_n of_o pulsion_n and_o such_o a_o one_o as_o be_v usual_o term_a trusion_n
