not_o bare_o or_o the_o account_n of_o the_o suppose_a antipathy_n betwixt_o the_o salt_n but_o because_o the_o cause_n of_o that_o seem_a antipathy_n do_v likewise_o upon_o a_o mechanical_a account_n

of_o the_o inducement_n i_o have_v to_o make_v the_o trial_n as_o well_o as_o of_o the_o success_n of_o they_o consider_v then_o that_o water_n will_v not_o dissolve_v salt_n indefinite_o but_o when_o
