be_v found_v and_o this_o be_v build_v upon_o the_o weight_n of_o ●ome_o gem_n which_o be_v great_a than_o ●hat_n which_o seem_v to_o belong_v to_o they_o ●s_v hard_a and_o transparent_a stone_n i_o

question_v how_o i_o come_v to_o know_v the_o truth_n of_o what_o i_o here_o deliver_v since_o though_o gem_n be_v wont_a to_o be_v estimate_v by_o lapidary_n as_o they_o weigh_v such_o or_o such_o a_o number_n of_o carrat_n or_o of_o grain_n yet_o they_o compare_v only_o the_o weight_n of_o this_o and_o that_o stone_n of_o the_o same_o kind_n in_o reference_n to_o one_o another_o as_o the_o great_a or_o lesser_a weight_n argue_v the_o great_a or_o lesser_a bulk_n without_o look_v after_o or_o know_v how_o to_o discover_v the_o specific_a gravity_n of_o several_a gem_n which_o depend_v not_o on_o the_o great_a or_o lesser_a bulk_n as_o if_o you_o know_v it_o not_o already_o you_o will_v gather_v from_o what_o i_o be_o now_o go_v to_o relate_v consider_v then_o with_o myself_o that_o for_o my_o purpose_n it_o be_v requisite_a to_o have_v a_o gem_n as_o free_a as_o i_o can_v get_v from_o the_o metalline_a mixture_n that_o i_o suspect_v many_o precious_a stone_n to_o have_v and_o remember_v that_o rock-cristal_n as_o it_o be_v by_o mineralist_n reckon_v among_o gem_n so_o it_o be_v hard_a enough_o as_o i_o try_v both_o to_o cut_v glass_n and_o to_o strike_v fire_n and_o that_o its_o have_v so_o great_a a_o transparency_n and_o its_o be_v devoid_a of_o colour_n make_v it_o exceed_o likely_a to_o be_v free_a from_o adventitious_a mixture_n i_o pitch_v upon_o it_o as_o the_o standard_n whereby_o to_o make_v a_o probable_a estimate_n of_o the_o weight_n of_o gem_n and_o have_v hydrostatical_o and_o with_o a_o tender_a balance_n examine_v the_o weight_n of_o it_o first_o in_o the_o air_n and_o then_o in_o water_n i_o find_v its_o weight_n to_o be_v to_o that_o of_o water_n of_o equal_a bulk_n as_o two_o and_o almost_o two_o three_o to_o one_o which_o by_o the_o way_n show_v we_o how_o groundless_o many_o learned_a man_n as_o well_o ancient_a as_o modern_a make_v crystal_n to_o be_v but_o ice_n extraordinary_o harden_v by_o a_o long_a and_o vehement_a cold_a whereas_o ice_n be_v bulk_n for_o bulk_n light_a than_o water_n and_o therefore_o swim_v upon_o it_o and_o to_o add_v that_o objection_n against_o the_o vulgar_a error_n madagascar_n and_o other_o country_n in_o the_o torrid_a zone_n abound_v with_o crystal_n have_v thus_o find_v the_o ponderousness_n of_o crystal_n in_o reference_n to_o water_n when_o i_o meet_v with_o a_o colour_a gem_n who_o specific_a gravity_n i_o guess_v to_o be_v sensible_o great_a i_o sometime_o give_v myself_o the_o trouble_n for_o a_o trouble_n it_o be_v to_o weigh_v they_o in_o the_o air_n and_o in_o the_o water_n and_o so_o discover_v whether_o i_o conjecture_v aright_o and_o if_o its_o specific_a gravity_n do_v much_o exceed_v that_o of_o crystal_n i_o think_v it_o a_o probable_a argument_n that_o there_o may_v be_v some_o metalline_a or_o mineral_n corpuscle_n mingle_v with_o the_o stony_a one_o of_o the_o gem_n and_o that_o also_o it_o may_v probable_o derive_v its_o tincture_n thence_o i_o will_v not_o tell_v you_o that_o i_o then_o find_v many_o sort_n of_o transparent_a stone_n much_o heavy_a than_o crystal_n for_o beside_o that_o the_o trial_n be_v troublesome_a enough_o to_o make_v i_o chance_v to_o fall_v upon_o they_o in_o a_o place_n where_o i_o have_v not_o any_o store_n and_o variety_n of_o gem_n to_o examine_v but_o one_o instance_n among_o those_o that_o occur_v to_o i_o i_o shall_v here_o set_v down_o because_o be_v so_o notable_a it_o may_v suffice_v to_o show_v that_o as_o to_o some_o gem_n at_o least_o my_o opinion_n of_o their_o have_v a_o adventitious_a gravity_n and_o consequent_o ingredient_n be_v very_o probable_a i_o have_v some_o american_n granat_n which_o i_o have_v a_o great_a and_o peculiar_a reason_n to_o believe_v have_v be_v once_o liquid_a body_n and_o therefore_o think_v they_o the_o more_o worthy_a to_o be_v examine_v and_o find_v their_o colour_n to_o be_v so_o deep_a that_o they_o be_v almost_o opacous_a and_o judge_v by_o my_o hand_n that_o they_o be_v much_o heavy_a than_o piece_n of_o crystal_n of_o the_o same_o bulk_n will_v be_v i_o weigh_v they_o in_o a_o pair_n of_o nice_a scale_n in_o the_o air_n and_o in_o the_o water_n and_o find_v they_o as_o i_o expect_v to_o be_v almost_o four_o time_n as_o heavy_a as_o water_n of_o the_o same_o bulk_n and_o consequent_o heavy_a by_o about_o a_o three_o part_n than_o piece_n of_o crystal_n equal_v they_o in_o bigness_n will_v be_v whence_o so_o great_a a_o accession_n of_o ponderousness_n proceed_v i_o shall_v tell_v you_o when_o i_o come_v to_o my_o next_o argument_n to_o which_o i_o shall_v advance_v as_o soon_o as_o i_o have_v note_v that_o though_o when_o colour_a gem_n have_v a_o great_a gravity_n than_o crystal_n it_o be_v a_o probable_a argument_n that_o they_o have_v some_o metalline_a pigment_n or_o other_o mineral_n substance_n mingle_v with_o they_o yet_o if_o such_o gem_n have_v no_o such_o surplusage_n of_o weight_n it_o will_v not_o follow_v that_o their_o colour_n can_v proceed_v from_o any_o mineral_n tincture_n since_o it_o be_v not_o unreasonable_a to_o conceive_v that_o a_o mineral_n substance_n may_v be_v present_a in_o a_o liquor_n such_o as_o the_o lapidescent_n juice_n that_o we_o suppose_v gem_n to_o be_v make_v of_o even_o when_o it_o add_v no_o manifest_a weight_n to_o the_o body_n that_o harbour_v it_o since_o i_o have_v observe_v what_o be_v odd_a that_o a_o mineral_n water_n which_o by_o its_o taste_n its_o effect_n and_o the_o colour_n it_o will_v strike_v appear_v to_o be_v rich_o impregnate_v with_o iron_n be_v careful_o by_o i_o examine_v hydrostatical_o do_v appear_v very_o little_a if_o at_o all_o sensible_o heavy_a than_o common_a water_n the_o three_o and_o last_o argument_n i_o shall_v now_o make_v use_n of_o be_v take_v from_o hence_o that_o out_o of_o divers_a medicinal_a stone_n and_o even_o out_o of_o some_o fine_a gem_n real_a and_o corporeal_a metal_n or_o other_o mineral_n substance_n may_v be_v extract_v of_o this_o argument_n i_o shall_v at_o present_a say_v the_o less_o because_o the_o further_a prosecution_n of_o it_o will_v be_v more_o proper_a in_o the_o second_o part_n of_o this_o discourse_n where_o i_o shall_v be_v oblige_v to_o handle_v it_o with_o reference_n to_o opacous_a gem_n in_o which_o its_o force_n will_v best_o appear_v and_o therefore_o i_o shall_v desire_v you_o to_o take_v notice_n when_o you_o arrive_v at_o that_o part_n of_o the_o subsequent_a discourse_n of_o those_o particular_n that_o may_v serve_v to_o strengthen_v the_o new_o propose_v argument_n and_o if_o it_o be_v object_v that_o the_o body_n there_o treat_v of_o be_v opacous_a stone_n not_o gem_n i_o have_v these_o thing_n to_o answer_v first_o that_o divers_a stone_n that_o be_v reckon_v among_o precious_a one_o be_v opacous_a too_o as_o the_o turquois_n the_o onyx_n the_o sardonix_n etc._n etc._n not_o to_o mention_v divers_a other_o as_o cats-eye_n opale_n etc._n etc._n which_o be_v as_o it_o be_v semi-opacous_a beside_o i_o much_o question_n whether_o diaphaneity_n be_v absolute_o necessary_a to_o the_o essence_n though_o it_o be_v to_o the_o beauty_n of_o those_o precious_a stone_n wherein_o it_o be_v usual_o find_v and_o i_o may_v here_o make_v it_o probable_a by_o discourse_n that_o transparency_n and_o opacity_n oftentimes_o depend_v but_o upon_o the_o manner_n of_o the_o pigmen_n dispersion_n through_o the_o stony_a matter_n of_o the_o gem_n and_o the_o convenient_a or_o inconvenient_a situation_n of_o the_o pore_n in_o reference_n to_o the_o beam_n of_o light_n but_o wave_v this_o speculative_a argument_n i_o shall_v rather_o take_v notice_n that_o several_a precious_a stone_n and_o even_a diamond_n themselves_o have_v sometime_o great_a cloud_n which_o make_v they_o in_o those_o part_n almost_o if_o not_o quite_o opacous_a without_o be_v thereby_o hinder_v from_o be_v true_a diamond_n or_o gem_n of_o this_o or_o that_o kind_n to_o which_o their_o hardness_n colour_n etc._n etc._n make_v they_o appertain_v and_o not_o to_o mention_v cornelion_n agat_n and_o some_o other_o stone_n that_o we_o may_v observe_v to_o be_v as_o the_o ting_a corpuscle_n happen_v to_o be_v in_o a_o due_a or_o a_o over_o great_a proportion_n mix_v with_o the_o petrescent_a matter_n and_o to_o be_v uniformly_n or_o inconvenient_o mingle_v with_o it_o some_o of_o they_o transparent_a and_o some_o of_o they_o semi-diaphanous_a i_o have_v see_v wear_v in_o

to_o do_v consider_v this_o i_o say_v i_o dissolve_v the_o stony_a stiriae_fw-la in_o this_o liquor_n and_o have_v suffer_v some_o of_o it_o to_o evaporate_v away_o and_o put_v the_o rest_n into_o a_o

sort_n of_o nitre_n with_o some_o part_n also_o of_o the_o stony_a solution_n i_o mix_v in_o a_o convenient_a proportion_n a_o high_a colour_a solution_n of_o copper_n make_v likewise_o in_o spirit_n of_o verdigreas_n and_o these_o two_o solution_n be_v make_v with_o the_o same_o menstruum_fw-la and_o wary_o enough_o put_v together_o do_v not_o precipitate_v one_o another_o but_o afford_v i_o

i_o shall_v now_o therefore_o proceed_v to_o those_o other_o consideration_n which_o be_v assist_v by_o what_o have_v be_v already_o say_v may_v i_o hope_v suffice_v to_o keep_v our_o conjecture_n about_o the_o cause_n of_o the_o virtue_n of_o gem_n from_o seem_v unreasonable_a and_o my_o first_o observation_n shall_v be_v that_o not_o only_o there_o be_v in_o the_o earth_n a_o great_a number_n and_o variety_n of_o mineral_n already_o know_v by_o particular_a name_n but_o probable_o there_o be_v very_o many_o other_o that_o be_v not_o yet_o know_v to_o we_o the_o former_a part_n of_o this_o proposition_n will_v not_o be_v doubt_v by_o those_o that_o consider_v how_o great_a a_o multitude_n of_o metalline_a oar_n marchasite_n of_o several_a sort_n antimony_n tinn'd-glass_n fluore_n talk_v

of_o musaeum_n and_o other_o collection_n of_o natural_a rarity_n insomuch_o that_o of_o only_o one_o kind_a of_o fossils_n the_o diligence_n of_o some_o modern_a writer_n have_v reckon_v up_o

etc._n and_o as_o for_o the_o second_o part_n of_o our_o proposition_n or_o observation_n you_o will_v scarce_o deny_v it_o though_o you_o consider_v with_o i_o but_o these_o two_o thing_n the_o first_o be_v the_o small_a and_o inconsiderable_a proportion_n that_o the_o perpendicular_a depth_n that_o the_o generality_n of_o mine_n bear_v to_o the_o semidiameter_n of_o the_o earth_n reckon_v to_o be_v above_o 3500_o mile_n so_o that_o though_o our_o globe_n be_v inhabit_v by_o some_o hundred_o of_o million_o of_o man_n more_o than_o now_o it_o be_v and_o they_o have_v curiosity_n enough_o

undiscovered_a and_o to_o this_o first_o observation_n i_o shall_v subjoin_v this_o second_o that_o as_o far_o as_o i_o have_v observe_v almost_o every_o region_n afford_v mineral_n of_o its_o own_o differ_v from_o those_o that_o be_v take_v notice_n of_o in_o other_o region_n and_o in_o particular_a country_n as_o in_o some_o shire_n of_o england_n a_o curious_a and_o heedful_a eye_n may_v i_o

in_o general_a that_o in_o some_o part_n of_o england_n where_o i_o have_v more_o opportunity_n than_o in_o other_o to_o exercise_v some_o curiosity_n about_o mineral_n i_o meet_v sometime_o in_o a_o

have_v receive_v divers_a other_o from_o several_a part_n both_o of_o the_o old_a world_n and_o the_o new_a in_o the_o next_o place_n i_o consider_v that_o nature_n have_v furnish_v the_o earth_n

a_o improvement_n of_o this_o first_o answer_n may_v furnish_v i_o with_o the_o second_o for_o hence_o we_o may_v argue_v that_o it_o be_v not_o impossible_a that_o the_o principal_a virtue_n of_o a_o
