body_n by_o mean_n of_o alteration_n that_o appear_v not_o to_o be_v other_o than_o mechanical_a exper._n i._n and_o first_o have_v with_o a_o very_a mild_a heat_n slow_o evaporate_v about_o a_o four_o part_n of_o good_a turpentine_n i_o find_v that_o the_o remain_a body_n will_v not_o when_o cold_a continue_v a_o liquor_n but_o harden_v into_o a_o transparent_a gum_n almost_o like_o amber_n which_o as_o i_o look_v for_o prove_v electrical_a exper._n ii_o second_o by_o mix_v two_o such_o liquid_a body_n as_o petroleum_n and_o strong_a spirit_n of_o nitre_n in_o a_o certain_a proportion_n and_o then_o distil_v they_o till_o there_o remain_v a_o dry_a mass_n i_o obtain_v a_o brittle_a substance_n as_o black_a as_o jet_v and_o who_o superficies_n where_o it_o be_v contiguous_a to_o the_o retort_n be_v glossie_n like_o that_o mineral_n when_o polish_a and_o as_o i_o expect_v i_o find_v it_o also_o to_o resemble_v jet_n in_o be_v endow_v with_o a_o electrical_a faculty_n exper._n iii_o three_o have_v burn_v antimony_n to_o ash_n and_o of_o those_o ash_n without_o any_o addition_n make_v a_o transparent_a glass_n i_o find_v that_o when_o rub_v as_o electrical_a body_n ought_v to_o be_v to_o excite_v they_o it_o answer_v my_o expectation_n by_o manifest_v a_o not_o inconsiderable_a electricity_n and_o this_o be_v the_o worthy_a of_o notice_n because_o that_o as_o a_o

part_n of_o the_o antimonial_a sulphur_n be_v separate_v and_o leave_v among_o the_o scoriae_fw-la so_o glass_n of_o antimony_n make_v without_o additament_n may_v easy_o as_o experience_n have_v inform_v we_o be_v in_o part_n reduce_v to_o a_o regulus_n a_o body_n not_o reckon_v among_o electrical_a one_o and_o that_o you_o may_v not_o think_v that_o it_o be_v only_o some_o peculiar_a and_o fix_a part_n of_o the_o antimony_n that_o be_v capable_a of_o vitrification_n let_v i_o assure_v you_o that_o even_o with_o the_o other_o part_n that_o be_v wont_a to_o fly_v away_o namely_o the_o flower_n a_o antimonial_a glass_n may_v without_o a_o addition_n of_o other_o ingredient_n be_v make_v exper._n iu._n fourthly_o the_o mention_n of_o a_o vitrified_a body_n bring_v into_o my_o mind_n that_o i_o more_o than_o once_o make_v some_o glass_n of_o lead_n per_fw-la se_fw-la which_o i_o find_v no_o very_a easy_a work_n that_o also_o be_v not_o whole_o destitute_a of_o a_o electrical_a

and_o oil_n the_o retort_n be_v wary_o break_v and_o the_o remain_a matter_n be_v take_v out_o in_o a_o lump_n which_o though_o it_o have_v quite_o lose_v its_o colour_n be_v burn_v quite_o black_a and_o though_o it_o be_v grow_v strange_o brittle_a in_o comparison_n of_o amber_n so_o that_o they_o who_o believe_v the_o virtue_n of_o attract_v light_a body_n to_o flow_v from_o the_o substantial_a form_n of_o amber_n will_v not_o expect_v it_o in_o a_o body_n so_o change_v and_o deprive_v of_o its_o noble_a part_n yet_o this_o caput_fw-la mortuum_fw-la be_v so_o far_o from_o

from_o the_o forego_n instance_n afford_v we_o by_o the_o glass_n of_o antimony_n we_o may_v learn_v that_o when_o the_o form_n of_o a_o body_n seem_v to_o be_v destroy_v by_o a_o fiery_a analysis_n that_o dissipate_v the_o part_n of_o it_o the_o remain_a substance_n may_v yet_o be_v endow_v with_o electricity_n as_o the_o caput_fw-la mortuum_fw-la of_o amber_n â—ay_v acquire_v it_o as_o in_o the_o case_n of_o the_o glass_n of_o antimony_n make_v of_o the_o calx_fw-la and_o of_o the_o flower_n and_o from_o the_o second_o example_n abovementioned_a and_o from_o common_a glass_n which_o be_v

to_o proceed_v from_o the_o substantial_a or_o even_o from_o the_o essential_a form_n of_o the_o attrahent_fw-la but_o may_v be_v the_o effect_n of_o unheeded_a and_o as_o it_o be_v fortuitous_a
