observation_n 4._o the_o four_o circumstance_n which_o may_v be_v allege_v to_o the_o same_o purpose_n with_o the_o three_o forego_v be_v that_o it_o seem_v possible_a from_o some_o gem_n by_o menstruum_n to_o obtain_v tincture_n that_o seem_v rather_o extraction_n than_o dissolution_n strict_o so_o call_v i_o will_v not_o urge_v the_o chemical_a process_n that_o may_v be_v meet_v with_o in_o some_o author_n to_o this_o effect_n because_o some_o circumstance_n in_o the_o thing_n and_o in_o the_o writer_n make_v i_o so_o far_o suspect_v those_o i_o can_v try_v and_o those_o that_o require_v undiscovered_a menstruum_n as_o they_o may_v be_v true_a so_o for_o aught_o i_o know_v they_o may_v not_o as_o to_o keep_v i_o from_o meddle_v with_o they_o but_o i_o remember_v i_o once_o make_v a_o menstruum_fw-la i_o say_v once_o because_o its_o preparation_n be_v so_o subject_a to_o casualty_n that_o i_o have_v often_o fail_v in_o it_o which_o be_v pour_v upon_o well_o colour_v

i_o show_v it_o because_o the_o menstruum_fw-la be_v not_o more_o corrosive_a than_o white-wine_n and_o which_o yet_o i_o therefore_o take_v to_o be_v a_o genuine_a tincture_n partly_o because_o it_o be_v draw_v in_o the_o cold_a partly_o because_o the_o liquor_n will_v not_o thing_fw-mi itself_o by_o stand_v if_o no_o body_n be_v put_v in_o it_o and_o partly_o because_o it_o draw_v a_o tincture_n from_o antimony_n of_o a_o very_a differ_a colour_n from_o this_o we_o speak_v of_o nor_o be_v granat_n the_o only_a gem_n which_o i_o have_v make_v the_o liquor_n work_v on_o in_o the_o cold._n 5._o to_o these_o four_o circumstance_n i_o shall_v add_v this_o five_o that_o some_o gem_n which_o jeweller_n affirm_v without_o scruple_n to_o be_v ruby_n saphire_n etc._n etc._n either_o be_v colourless_a or_o have_v other_o colour_n than_o those_o that_o be_v wont_a to_o belong_v to_o they_o that_o famous_a goldsmith_n benvenuto_n cellini_n in_o his_o little_a italian_a tract_n of_o his_o own_o profession_n admonish_v his_o reader_n 10._o page_n 10._o that_o there_o be_v one_o kind_n of_o ruby_n that_o be_v natural_o white_a and_o not_o make_v so_o by_o art_n which_o he_o prove_v by_o the_o degree_n of_o hardness_n peculiar_a to_o ruby_n and_o the_o same_o author_n elsewhere_o tell_v we_o of_o berill_n topaz_n and_o amethyst_n that_o be_v white_a and_o it_o seem_v by_o what_o he_o say_v not_o far_o from_o that_o place_n that_o the_o italian_a jeweller_n do_v not_o look_v upon_o the_o tincture_n of_o gem_n as_o any_o thing_n near_o so_o essential_a to_o they_o as_o they_o be_v common_o repute_v since_o they_o reckon_v topaz_n and_o saphire_n whereof_o one_o be_v blue_a and_o the_o other_o yellow_a but_o both_o extreme_o hard_a in_o comparison_n of_o other_o gem_n than_o diamond_n and_o perhaps_o ruby_n to_o be_v of_o the_o same_o species_n the_o degree_n of_o hardness_n of_o ruby_n and_o saphire_n be_v oftentimes_o so_o equal_a that_o i_o know_v a_o expert_a english_a jeweller_n who_o for_o that_o only_a reason_n for_o he_o know_v not_o whence_o the_o difference_n of_o colour_n may_v proceed_v take_v ruby_n and_o saphire_n to_o be_v of_o the_o same_o kind_n of_o stone_n and_o that_o gem_n refer_v by_o lapidary_n to_o the_o same_o kind_n may_v be_v very_o differ_o tinge_v be_v a_o truth_n whereof_o i_o have_v see_v notable_a instance_n in_o diamond_n themselves_o which_o i_o therefore_o prefer_v to_o other_o instance_n because_o the_o extreme_a hardness_n of_o diamond_n be_v such_o as_o keep_v jeweller_n from_o mistake_v any_o other_o stone_n for_o a_o true_a diamond_n if_o they_o be_v permit_v to_o put_v they_o on_o their_o rapid_o move_a wheel_n employ_v to_o cut_v they_o now_o of_o true_a diamond_n i_o have_v see_v some_o that_o be_v yellowish_a other_o that_o be_v more_o yellow_a and_o among_o the_o rest_n one_o that_o be_v so_o perfect_o yellow_a that_o i_o at_o first_o take_v it_o for_o a_o fair_a topaz_n though_o it_o be_v a_o diamond_n value_v at_o near_o three_o pound_n weight_n of_o gold_n i_o have_v also_o see_v diamond_n and_o those_o rough_a as_o they_o come_v direct_o out_o of_o the_o indies_n and_o be_v soon_o after_o buy_v by_o trader_n in_o diamond_n for_o such_o which_o be_v either_o bluish_a or_o greenish_a and_o i_o particular_o contemplate_v one_o stone_n which_o if_o its_o shape_n and_o other_o thing_n have_v not_o convince_v i_o of_o the_o contrary_a be_v so_o green_a that_o i_o shall_v have_v take_v it_o for_o a_o emerald_n i_o remember_v i_o have_v once_o occasion_n to_o buy_v a_o considerable_a number_n of_o small_a ruby_n divers_a of_o which_o be_v very_o curious_o shape_v and_o come_v to_o look_v upon_o the_o whole_a parcel_n more_o leisurely_o than_o my_o haste_n will_v permit_v i_o when_o i_o buy_v it_o i_o find_v in_o a_o great_a number_n of_o other_o stone_n one_o and_o but_o one_o that_o be_v devoid_a of_o any_o colour_n but_o in_o other_o respect_n be_v so_o like_o the_o rest_n as_o invite_v i_o to_o conclude_v that_o it_o will_v have_v increase_v their_o number_n but_o that_o it_o be_v coagulate_v and_o harden_v before_o the_o mineral_n pigment_n have_v tinge_v it_o of_o the_o same_o colour_n with_o the_o rest_n in_o which_o guess_n i_o be_v confirm_v when_o have_v meet_v with_o a_o gentleman_n who_o have_v be_v in_o the_o chief_a place_n of_o the_o east_n indies_n where_o ruby_n be_v find_v and_o particular_o at_o the_o river_n of_o siam_n or_o pegu_n near_o which_o he_o live_v a_o good_a while_n and_o where_o he_o frequent_o see_v ruby_n take_v out_o of_o the_o bottom_n of_o the_o water_n and_o sometime_o take_v they_o out_o himself_o i_o learn_v of_o he_o by_o enquiry_n that_o he_o have_v there_o see_v several_a stone_n each_o of_o which_o be_v partly_o a_o ruby_n and_o partly_o colourless_a and_o sometime_o in_o the_o same_o stone_n there_o will_v be_v two_o portion_n of_o one_o sort_n and_o the_o three_o though_o lie_v betwixt_o they_o of_o another_o which_o have_v frequent_o oblige_v the_o jeweller_n considerable_o to_o lessen_v the_o bulk_n of_o such_o stone_n by_o cut_v off_o the_o untincted_a part_n and_o if_o my_o memory_n do_v not_o much_o deceive_v i_o i_o see_v in_o a_o great_a and_o curious_a prince_n cabinet_n among_o other_o rarity_n a_o ring_n in_o which_o be_v set_v a_o stone_n of_o a_o moderate_a

agat_n and_o in_o opacous_a gem_n i_o can_v easy_o give_v a_o multitude_n of_o instance_n of_o the_o differ_o tinct_a part_n of_o the_o same_o entire_a stone_n and_o i_o usual_o wear_v in_o a_o ring_n a_o small_a sardonix_n that_o be_v once_o a_o great_a prince_n wherein_o there_o be_v three_o portion_n one_o within_o another_o the_o uppermost_a black_a the_o middlemost_a of_o a_o kind_n of_o chesnut_n colour_n the_o other_o of_o a_o blue_n almost_o like_o a_o turquois_n each_o of_o which_o portion_n be_v exact_o of_o a_o fine_a oval_a figure_n and_o each_o of_o the_o two_o uttermost_a be_v throughout_o of_o a_o very_a uniform_a breadth_n as_o well_o as_o colour_n and_o exact_o parallel_v to_o the_o other_o but_o it_o will_v not_o be_v here_o so_o proper_a as_o it_o will_v be_v hereafter_o to_o multiply_v instance_n of_o opacous_a gem_n wherefore_o have_v mention_v only_o the_o sardonix_n because_o it_o be_v not_o always_o opacous_a i_o shall_v add_v concern_v transparent_a one_o that_o jeweller_n reckon_v among_o saphire_n not_o only_o that_o sort_n of_o azure_a gem_n which_o usual_o pass_v for_o such_o but_o also_o another_o sort_n of_o stone_n because_o of_o their_o saphirine_n degree_n of_o hardness_n though_o for_o their_o want_n of_o tincture_n they_o call_v they_o white_a saphire_n 6._o the_o six_o and_o last_o circumstance_n belong_v to_o the_o forego_n argument_n or_o consideration_n be_v this_o that_o sometime_o one_o may_v find_v gem_n that_o be_v partly_o tinct_a and_o partly_o not_o as_o if_o the_o tinge_a pigment_n mix_v with_o one_o part_n of_o the_o matter_n whereof_o the_o stone_n consist_v whilst_o it_o be_v liquid_a or_o soft_a be_v not_o copious_a enough_o to_o diffuse_v itself_o to_o the_o whole_a nor_o to_o give_v a_o equal_o intense_a colour_n to_o all_o that_o portion_n that_o it_o tinge_v it_o be_v true_a that_o in_o some_o case_n the_o diffusion_n may_v be_v stop_v by_o the_o petrescent_a juice_n coagulate_v first_o in_o another_o part_n than_o that_o with_o which_o the_o tincture_n be_v mix_v and_o perhaps_o

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 think_v ●e_n may_v probable_o derive_v it_o from_o metalline_n or_o mineral_n mixture_n i_o question_v not_o but_o as_o you_o will_v think_v this_o allegation_n new_a so_o you_o will_v be_v apt_a to_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
