the_o angle_n of_o parallax_n be_v still_o the_o more_o sensible_a therefore_o the_o best_a place_n to_o complete_a this_o observation_n be_v in_o some_o place_n under_o the_o polar_a circle_n as_o in_o iseland_n where_o the_o zenith_n of_o the_o place_n at_o the_o time_n abovesaid_a must_v consequent_o pass_v at_o one_o time_n to_o the_o north_n side_n of_o the_o pole_n of_o the_o ecliptic_a
