whether_o the_o submarine_n coldness_n do_v at_o the_o bottom_n of_o the_o sea_n or_o elsewhere_o either_o equal_a or_o surpass_v that_o degree_n which_o we_o here_o find_v sufficient_a to_o freezâ—_n

resist_v the_o ascension_n of_o the_o subjacent_a mercury_n more_o than_o indeed_o it_o will_n we_o make_v then_o a_o small_a weatherglass_n differ_v from_o common_a one_o beside_o the_o bigness_n in_o that_o it_o be_v turnish_v with_o mercury_n instead_o of_o water_n and_o in_o that_o we_o employ_v to_o contain_v the_o stagnant_a mercury_n a_o glass_n vial_n with_o a_o narrow_a neck_n

i_o think_v fit_a to_o admonish_v the_o spectator_n of_o that_o it_o be_v not_o to_o be_v expect_v that_o the_o mercury_n shall_v rise_v as_o much_o in_o proportion_n when_o it_o be_v for_o example_n a_o foot_n under_o water_n as_o when_o it_o be_v but_o two_o or_o three_o inch_n because_o according_a as_o the_o instrument_n be_v let_v down_o deep_o and_o the_o air_n crowd_v into_o a_o less_o
