follow_v that_o as_o much_o water_n as_o be_v draw_v up_o above_o the_o level_n of_o the_o whole_a bulk_n in_o the_o cistern_n must_v needs_o press_v into_o the_o sink_a arm_n from_o the_o next_o

nothing_o violent_v it_o to_o rest_v in_o the_o place_n that_o the_o ascend_a water_n which_o be_v low_o than_o it_o leau_v at_o liberty_n for_o it_o to_o take_v possession_n of_o and_o then_o it_o can_v be_v doubt_v but_o that_o this_o descend_a water_n have_v all_o its_o weight_n in_o press_v down_o apply_v to_o drive_v up_o the_o rise_a water_n in_o the_o sink_a arm_n of_o the_o syphon_n &_o

must_v needs_o draw_v the_o water_n that_o be_v the_o other_o immersed_a arm_n as_o long_o as_o the_o end_n of_o its_o pipe_n reach_v low_a than_o the_o level_n of_o the_o water_n in_o the_o cistern_n for_o so_o long_o it_o appear_v by_o what_o we_o have_v say_v it_o must_v needs_o be_v more_o weighty_a since_o part_v of_o the_o rise_a water_n in_o the_o sink_a arm_n of_o the_o syphon_n be_v coum_n erpoise_v by_o as_o much_o descend_a water_n in_o the_o cistern_n and_o thus_o it_o be_v evident_a that_o out_o of_o this_o experiment_n it_o can_v be_v infer_v that_o part_n of_o water_n do_v not_o weigh_v within_o the_o orb_n of_o their_o own_o whole_a but_o only_o that_o two_o equal_a part_n of_o water_n in_o their_o own_o orb_n namely_o that_o which_o rise_v in_o the_o sink_a arm_n and_o that_o which_o press_v down_o from_o the_o whole_a bulk_n in_o the_o cistern_n be_v of_o equal_a weight_n and_o balance_n one_o another_o so_o that_o never_o so_o little_a odds_o between_o the_o two_o

pass_v so_o if_o we_o conceive_v the_o superficies_n from_o which_o the_o light_n reflect_v to_o be_v diverse_o order_v in_o respect_n of_o reflection_n it_o must_v of_o necessity_n follow_v that_o it_o will_v have_v a_o divers_a lustre_n and_o sight_n as_o we_o see_v by_o experience_n in_o the_o neck_n of_o pigeon_n and_o in_o certain_a position_n of_o our_o eye_n in_o which_o the_o light_n pass_v through_o our_o eyebrow_n make_v a_o appearance_n as_o though_o we_o see_v divers_a colour_n stream_v from_o a_o candle_n we_o look_v upon_o and_o according_o we_o may_v observe_v how_o some_o thing_n or_o rather_o most_v appear_v of_o a_o colour_n more_o incline_v to_o white_a when_o they_o be_v irradiate_v with_o a_o great_a light_n then_o when_o they_o stand_v in_o a_o lesser_a and_o we_o see_v painter_n heighten_v their_o colour_n and_o make_v they_o appear_v light_a by_o place_v deep_a shadow_n by_o they_o even_o so_o much_o that_o they_o will_v make_v object_n appear_v near_o

appear_v the_o clear_a as_o the_o other_o do_v more_o dusky_a wherefore_o if_o we_o put_v the_o superficies_n of_o one_o body_n to_o have_v a_o colour_n better_a disposition_n for_o the_o reflection_n of_o light_n than_o another_o have_v we_o can_v but_o conceive_v that_o such_o difference_n in_o the_o superficies_n must_v needs_o beget_v variety_n of_o permanent_a colour_n in_o the_o body_n and_o according_a as_o the_o superficies_n of_o the_o same_o body_n be_v better_a or_o worse_o dispose_v to_o reflection_n of_o light_n by_o polish_n or_o by_o compressure_n together_o or_o the_o like_a

through_o which_o it_o pass_v in_o they_o therefore_o and_o in_o nothing_o else_o we_o be_v to_o make_v our_o enquiry_n to_o begin_v then_o we_o may_v observe_v that_o light_n pass_v through_o a_o

we_o may_v observe_v that_o those_o beam_n which_o continue_v light_a and_o endure_v very_o little_a mutation_n by_o their_o passage_n make_v as_o many_o refraction_n make_v much_o great_a deflexion_n

which_o hinder_v they_o from_o appear_v at_o the_o first_o and_o in_o like_a manner_n if_o you_o put_v a_o burn_a glass_n between_o the_o light_n and_o the_o prism_n so_o as_o to_o multiply_v the_o

thus_o you_o have_v the_o true_a and_o adequate_a cause_n of_o the_o appearance_n of_o such_o colour_n now_o to_o understand_v what_o colour_n and_o upon_o which_o side_n will_v prism_n appear_v we_o may_v consider_v that_o when_o light_n pass_v through_o a_o glass_n or_o other_o diaphanous_a body_n so_o much_o of_o it_o as_o shine_v in_o the_o air_n or_o upon_o some_o reflect_a body_n big_a

which_o proceed_v from_o the_o light_n to_o the_o two_o side_n of_o the_o superficies_n at_o which_o the_o light_n enter_v be_v so_o refract_v that_o at_o their_o come_n out_o again_o through_o the_o
