that_o they_o be_v not_o all_o necessary_a though_o useful_a nor_o yet_o of_o equal_a moment_n and_o therefore_o the_o omission_n of_o some_o that_o be_v less_o important_a may_v not_o disappoint_v the_o main_a search_n 2._o i_o have_v purposely_o make_v most_o of_o the_o trial_n as_o easy_a and_o short_a as_o the_o matter_n and_o scope_n will_v permit_v and_o those_o that_o will_v not_o

the_o toil_n oftentimes_o make_v a_o part_n of_o the_o pleasure_n and_o i_o have_v make_v the_o less_o scruple_n to_o be_v somewhat_o ample_a in_o the_o inquiry_n i_o propound_v because_o divers_a observation_n have_v persuade_v i_o that_o physician_n ought_v to_o consider_v very_o well_o both_o the_o nature_n of_o the_o water_n they_o ordain_v and_o to_o what_o person_n for_o what_o disease_n and_o in_o what_o manner_n they_o prescribe_v the_o use_n of_o they_o for_o though_o many_o look_v upon_o they_o as_o such_o innocent_a medicine_n as_o if_o they_o do_v no_o good_a can_v at_o least_o do_v no_o harm_n yet_o the_o effect_n that_o have_v too_o often_o ensue_v the_o unskilful_a use_n of_o they_o especial_o when_o it_o be_v long_o continue_v allow_v i_o not_o to_o look_v upon_o the_o drink_n of_o mineral_n water_n as_o a_o slight_a thing_n that_o may_v safe_o be_v play_v with_o but_o as_o that_o whereby_o we_o have_v see_v as_o very_o much_o good_a so_o a_o great_a deal_n of_o

that_o by_o a_o diligent_a inquiry_n there_o may_v be_v discover_v in_o england_n and_o in_o divers_a other_o country_n too_o a_o far_o great_a number_n than_o be_v yet_o imagine_v of_o mineral_n

find_v that_o divers_a mineral_n that_o either_o man_n know_v not_o what_o to_o make_v of_o or_o by_o reason_n of_o their_o pass_v under_o other_o name_n do_v not_o suspect_v to_o be_v martial_a do_v yet_o partake_v of_o and_o perhaps_o abound_v with_o part_n of_o a_o martial_a nature_n and_o i_o show_v in_o another_o paper_n about_o the_o magnetism_n of_o the_o earth_n that_o kindly_a provident_a nature_n or_o rather_o its_o divine_a author_n have_v under_o various_a disguise_n furnish_v our_o globe_n with_o a_o far_o great_a plenty_n and_o variety_n of_o iron_n oar_n and_o mineral_n that_o

more_o dispose_v than_o one_o will_v suspect_v such_o hard_a body_n can_v be_v to_o impregnate_n even_o such_o liquor_n as_o be_v not_o manifest_o acid_a and_o seem_v unlikely_a to_o be_v able_a to_o
