sober_a commander_n of_o a_o ship_n that_o come_v this_o year_n from_o the_o remote_a part_n of_o the_o great_a ocean_n that_o at_o about_o 35_o degree_n of_o southern_a latitude_n the_o tallow_n

to_o be_v very_o frequent_a and_o careful_a in_o sound_v inform_v i_o that_o some_o time_n at_o considerable_a distance_n from_o shore_n he_o have_v observe_v the_o sea_n to_o be_v 20_o 30_o or_o

wherefore_o for_o the_o proof_n of_o the_o propose_a paradox_n i_o will_v here_o set_v down_o a_o memorable_a relation_n which_o my_o inquiry_n get_v i_o from_o the_o diver_n elsewhere_o mention_v

of_o the_o sea_n where_o it_o be_v of_o any_o considerable_a depth_n answer_v i_o to_o this_o purpose_n that_o the_o wind_n be_v stiff_o so_o that_o the_o wave_n be_v manifest_o six_o or_o seven_o foot_n high_a above_o the_o surface_n of_o the_o water_n he_o find_v no_o sign_n of_o it_o at_o 15_o fathom_n deep_a but_o if_o the_o blast_n continue_v long_o than_o it_o move_v the_o mudd_n at_o

for_o far_a confirmation_n i_o shall_v add_v that_o have_v inquire_v of_o a_o great_a traveller_n who_o have_v assist_v at_o a_o rich_a pearl-fishing_a in_o east_n indies_n whether_o he_o have_v not_o

have_v see_v the_o divers_a take_v the_o water_n when_o the_o sea_n be_v so_o very_o rough_a that_o scarce_o any_o vessel_n will_v hazard_v themselves_o out_o of_o port_n that_o those_o return_v divers_a tell_v he_o that_o at_o the_o bottom_n they_o have_v find_v no_o disturbance_n of_o the_o water_n at_o all_o which_o be_v the_o more_o considerable_a because_o of_o the_o situation_n of_o that_o place_n where_o they_o dive_v for_o pearl_n for_o this_o be_v near_o the_o shore_n of_o manar_n and_o that_o itself_o be_v seal_v between_o the_o great_a island_n of_o ceylon_n and_o the_o

assure_v i_o that_o have_v sometime_o sail_v in_o great_a ship_n that_o draw_v much_o water_n as_o about_o 12_o or_o 15_o foot_n he_o have_v dive_v to_o the_o keel_n of_o the_o ship_n when_o they_o

of_o the_o wave_n and_o he_o far_o answer_v that_o when_o in_o america_n he_o learn_v to_o dive_v of_o the_o indian_n they_o teach_v he_o by_o their_o example_n to_o creep_v along_o by_o the_o rock_n and_o great_a stone_n that_o lie_v near_o the_o shore_n at_o the_o bottom_n of_o the_o water_n to_o shelter_v themselves_o from_o the_o stroke_n and_o other_o ill_a effect_n of_o the_o billow_n which_o near_o the_o shore_n and_o where_o the_o sea_n be_v so_o shallow_a as_o it_o be_v there_o do_v oftenhurt_a and_o endanger_v swimmer_n and_o unskillful_a divers_n but_o when_o they_o be_v by_o this_o mean_n get_v further_o from_o shore_n and_o into_o deep_a water_n they_o will_v secure_o leave_v the_o shelter_n they_o have_v till_o then_o make_v use_v of_o and_o swim_v within_o a_o few_o

beneath_o the_o surface_n of_o the_o water_n about_o the_o tranquillity_n of_o the_o low_a part_n of_o very_o deep_a water_n i_o have_v a_o suspicion_n which_o though_o i_o fear_v it_o may_v seem_v
