hard_a matter_n to_o obtain_v spirit_n fine_a enough_o for_o such_o a_o purpose_n i_o shall_v subjoin_v a_o more_o easy_a one_o which_o be_v that_o if_o spirit_n of_o salt_n be_v add_v to_o the_o white_a of_o a_o egg_n beat_v to_o a_o certain_a thinness_n the_o mixture_n will_v be_v so_o much_o coagulate_v as_o not_o to_o afford_v the_o least_o drop_n though_o the_o glass_n in_o which_o the_o

the_o one_o as_o well_o as_o the_o other_o but_o it_o do_v not_o only_o experimental_o appear_v that_o a_o consistent_a body_n may_v result_v from_o a_o mixture_n of_o two_o fluid_n but_o also_o that_o a_o fluid_a may_v undergo_v such_o a_o alteration_n as_o to_o be_v change_v into_o two_o consistent_a body_n and_o this_o be_v evident_a in_o distil_a salad_n oil_n since_o the_o substance_n draw_v over_o be_v devoid_a of_o fluidity_n as_o well_o as_o that_o which_o remain_v behind_o and_o to_o make_v it_o appear_v that_o the_o reason_n of_o it_o be_v the_o bare_a result_n of_o texture_n

of_o the_o way_n abovementioned_a yet_o general_o at_o least_o three_o of_o they_o be_v at_o once_o concern_v semidiaphanous_a several_a body_n general_o esteem_v opacous_a semidiaphanous_a from_o

to_o produce_v colour_n genuine_a the_o short_a duration_n of_o colour_n no_o argument_n of_o their_o not_o be_v genuine_a and_o from_o what_o
except_o their_o peculiar_a texture_n will_v render_v they_o more_o capable_a of_o be_v work_v on_o by_o the_o ray_n of_o light_n than_o other_o body_n otherwise_o soft_a than_o they_o but_o
