we_o have_v therefore_o three_o condition_n concur_v to_o make_v the_o motion_n more_o efficacious_a namely_o the_o density_n the_o sharpness_n and_o the_o bulk_n of_o the_o mooveable_a and_o more_o than_o these_o three_o we_o can_v not_o expect_v to_o find_v in_o a_o move_v body_n for_o quantity_n have_v but_o three_o determination_n one_o by_o density_n and_o rarity_n of_o which_o density_n
