have_v be_v some_o invisible_a partition_n between_o they_o but_o to_o return_v to_o the_o unminglable_a liquor_n we_o be_v former_o speak_v of_o the_o cause_n why_o these_o retain_v their_o distinct_a surface_n my_o present_a task_n do_v not_o oblige_v i_o to_o inquire_v into_o but_o this_o i_o shall_v observe_v in_o general_a that_o it_o seem_v to_o depend_v very_o much_o upon_o the_o texture_n of_o the_o particular_a liquor_n and_o perhaps_o too_o upon_o the_o peculiar_a motion_n of_o their_o minute_n part_n for_o i_o have_v observe_v that_o though_o pure_a spirit_n of_o wine_n and_o salt_n of_o tartar_n resolve_v into_o a_o liquor_n by_o the_o moisture_n of_o the_o air_n will_n when_o put_v together_o retain_v distinct_a surface_n or_o present_o regain_v they_o if_o you_o

curiosity_n to_o make_v a_o trial_n with_o oil_n of_o turpentine_n abstract_v skilful_o and_o with_o a_o very_a gentle_a fire_n for_o otherwise_o the_o experiment_n may_v easy_o miscarry_v from_o melt_v or_o at_o least_o well_o decrepitate_v sea-salt_n we_o find_v according_a to_o expectation_n that_o though_o there_o appear_v no_o visible_a alteration_n in_o the_o oil_n yet_o we_o can_v easy_o by_o shake_v confound_v it_o with_o pure_a spirit_n of_o wine_n moreover_o though_o lixiviate_v liquor_n and_o oil_n will_v not_o by_o a_o ordinary_a agitation_n be_v permanent_o join_v yet_o i_o have_v try_v that_o by_o digest_v a_o good_a while_o a_o solution_n of_o salt_n of_o tartar_n with_o oil_n of_o almond_n i_o can_v reduce_v they_o to_o a_o soft_a saponary_a substance_n which_o experiment_n make_v somewhat_o more_o to_o my_o present_a purpose_n than_o the_o common_a practice_n of_o soap-boilers_a because_o i_o do_v not_o as_o they_o boil_v away_o the_o water_n wherein_o the_o lixiviate_v salt_n be_v dissolve_v i_o may_v add_v also_o that_o if_o you_o put_v one_o part_n of_o quicksilver_n into_o about_o four_o part_n of_o oil_n of_o vitriol_n you_o will_v find_v at_o least_o if_o the_o experiment_n proceed_v always_o after_o the_o same_o manner_n as_o it_o have_v do_v with_o i_o that_o the_o two_o liquor_n will_v remain_v distinct_a whilst_o you_o keep_v they_o in_o the_o cold_a but_o if_o by_o degree_n of_o heat_n you_o bring_v the_o oil_n of_o vitriol_n to_o boil_v it_o will_v pierce_v the_o surface_n of_o the_o quicksilver_n and_o by_o partly_o incorporate_n with_o it_o reduce_v it_o to_o a_o substance_n very_o differ_v from_o what_o it_o be_v but_o because_o these_o two_o last_o experiment_n may_v be_v with_o less_o improbability_n than_o the_o two_o that_o precede_v they_o refer_v to_o other_o cause_n i_o shall_v no_o far_o insist_v on_o they_o but_o take_v notice_n of_o one_o thing_n more_o concern_v the_o difference_n of_o fluid_a

of_o those_o other_o and_o reduce_v they_o to_o determinate_a shape_n this_o i_o have_v take_v pleasure_n to_o consider_v in_o some_o chemical_a liquor_n which_o i_o have_v purposely_o put_v together_o for_o instance_n have_v pour_v spirit_n of_o wine_n upon_o oil_n of_o tartar_n per_fw-la deliquium_fw-la as_o chemist_n call_v it_o i_o find_v that_o the_o superficies_n wherein_o they_o touch_v each_o other_o be_v flat_a or_o as_o to_o sense_n parallel_n to_o the_o horizon_n but_o if_o this_o be_v do_v in_o a_o very_a slender_a or_o narrow_a glass_n with_o the_o mouth_n unstopped_a though_o the_o low_a surface_n of_o the_o spirit_n of_o wine_n which_o touch_v the_o other_o liquor_n appear_v very_o level_a yet_o the_o upper_a superficies_n which_o be_v contiguous_a to_o the_o

we_o suppose_v that_o oil_n as_o it_o will_v better_o fill_v up_o the_o little_a cavity_n of_o the_o stone_n so_o it_o will_v more_o exact_o keep_v â—ut_v the_o air_n and_o less_o easy_o vanish_v

thought_n not_o improper_a that_o this_o tract_n shall_v attend_v it_o as_o a_o kind_n of_o appendix_n without_o the_o first_o and_o last_o part_n of_o a_o letter_n whereof_o the_o body_n only_o be_v necessary_a to_o the_o design_n of_o it_o a_o essay_n of_o the_o intestine_a motion_n of_o the_o particle_n of_o quiescent_a solid_n where_o the_o absolute_a rest_n of_o body_n be_v call_v in_o question_n sect_n i._o to_o remove_v the_o doubt_n or_o scruple_n that_o begin_v to_o be_v discourse_v of_o just_a before_o we_o last_o part_v i_o shall_v need_v to_o do_v little_o more_o than_o enlarge_v the_o particular_n which_o you_o know_v i_o have_v then_o time_n but_o brief_o to_o make_v mention_n of_o for_o the_o state_n of_o the_o question_n be_v as_o you_o may_v remember_v this_o whether_o there_o be_v among_o body_n any_o absolute_a rest_n on_o which_o occasion_n i_o answer_v that_o rest_v be_v a_o word_n that_o to_o i_o seem_v somewhat_o ambiguous_a i_o think_v it_o be_v requisite_a to_o clear_v the_o sense_n of_o the_o question_n before_o i_o offer_v at_o answer_v it_o for_o the_o word_n rest_v when_o we_o speak_v of_o distinct_a mass_n of_o matter_n look_v upon_o as_o quiescent_n do_v in_o the_o vulgar_a acception_n of_o the_o term_n signify_v such_o a_o state_n of_o a_o visible_a and_o entire_a body_n or_o rather_o of_o the_o corpuscle_n it_o consist_v of_o that_o they_o be_v actual_o vnmoved_a as_o to_o sight_n the_o eye_n and_o perhaps_o not_o the_o touch_n be_v not_o able_a to_o discern_v any_o local_a motion_n in_o they_o consonant_o to_o this_o first_o member_n of_o the_o distinction_n of_o the_o word_n rest_v i_o brief_o intimate_v to_o the_o company_n that_o in_o this_o sense_n of_o a_o corpuscle_n be_v at_o rest_n i_o think_v it_o manifest_v that_o there_o be_v such_o a_o thing_n in_o rerum_fw-la natura_fw-la since_o without_o grant_v such_o a_o rest_n in_o the_o component_a particle_n of_o some_o kind_n of_o body_n as_o diamond_n iron_n porphiry_n etc._n etc._n it_o will_v be_v i_o conceive_v very_o hard_o to_o explain_v how_o there_o can_v be_v such_o solid_a mass_n as_o those_o mineral_n be_v make_v up_o of_o small_a and_o separable_a particle_n which_o be_v say_v i_o add_v that_o i_o see_v no_o reason_n why_o such_o a_o kind_n of_o firmness_n where_o the_o inward_a motion_n of_o the_o insensible_a particle_n be_v almost_o infinite_o slow_a may_v not_o suffice_v to_o give_v a_o account_n of_o as_o great_a a_o firmness_n as_o we_o use_v real_o to_o find_v among_o consistent_a body_n but_o whereas_o i_o have_v intimate_v to_o the_o company_n by_o the_o late_o begin_v distinction_n that_o beside_o this_o popular_a sense_n of_o the_o word_n rest_v there_o be_v a_o second_o more_o rigid_a and_o philosophical_a notion_n or_o kind_n of_o rest_n which_o for_o distinction_n sake_n may_v be_v call_v absolute_a or_o perfect_a rest_n which_o import_v a_o continuance_n of_o a_o body_n in_o the_o same_o place_n precise_o and_o include_v a_o absolute_a negation_n of_o all_o local_a motion_n though_o never_o so_o slow_a or_o imperceptible_a i_o tell_v they_o that_o in_o this_o rigid_a sense_n of_o the_o word_n rest_v i_o dare_v not_o affirm_v that_o there_o be_v any_o body_n at_o rest_n in_o the_o universe_n at_o least_o for_o any_o long_a time_n but_o willing_o allow_v it_o to_o be_v make_v a_o problem_n whether_o there_o be_v any_o or_o no_o add_v that_o perhaps_o i_o incline_v to_o the_o negative_a part_n of_o the_o question_n have_v thus_o historical_o sum_v up_o what_o pass_v betwixt_o we_o about_o the_o state_n of_o the_o controversy_n i_o need_v not_o tell_v you_o that_o the_o doubt_v i_o express_v be_v think_v to_o relish_v too_o much_o of_o a_o paradox_n and_o therefore_o since_o the_o company_n be_v quick_a separation_n allow_v i_o then_o no_o opportunity_n of_o enlarge_n and_o since_o i_o promise_v no_o better_a argument_n than_o may_v be_v expect_v in_o a_o point_n that_o i_o propose_v but_o as_o problematical_a i_o shall_v now_o endeavour_v to_o show_v you_o that_o the_o side_n of_o the_o problem_n i_o be_v judge_v incline_v to_o be_v at_o least_o
