An essay concerning a vacuum Wherein is endeavoured to be demonstrated, that a vacuum interspersum runs through the world, and is more or less in all bodies. By a lover of the corpuscular philosophy.

air_n or_o thin_a substance_n call_v it_o what_o you_o please_v within_o the_o cavity_n of_o cork_n than_o in_o the_o pore_n of_o lead_n but_o this_o do_v not_o solve_v the_o difficulty_n unless_o it_o can_v be_v prove_v that_o a_o rarefy_a body_n together_o with_o the_o materia_fw-la subtilis_fw-la therein_o comprehend_v have_v equal_a closeness_n of_o part_n with_o a_o body_n more_o

place_n and_o that_o which_o have_v empty_a space_n of_o its_o own_o can_v never_o fill_v the_o cavity_n of_o another_o body_n as_o have_v be_v say_v but_o let_v we_o hear_v what_o account_n our_o

and_o subtle_a than_o all_o other_o matter_n see_v all_o matter_n be_v equal_o dense_a and_o solid_a but_o this_o matter_n say_v they_o be_v exceed_o rarefy_a nevertheless_o the_o difficulty_n be_v still_o the_o same_o viz._n how_o come_v it_o to_o be_v more_o rarefy_v they_o will_v tell_v we_o it_o proceed_v from_o the_o non-compression_n of_o the_o part_n but_o then_o their_o distance_n will_v be_v the_o great_a and_o so_o they_o grant_v there_o be_v vacuum_n and_o interval_n for_o unless_o these_o be_v grant_v the_o part_n be_v as_o much_o compress_v as_o in_o condense_a matter_n but_o if_o they_o be_v as_o much_o compress_v they_o be_v not_o more_o remote_a from_o one_o another_o and_o if_o they_o be_v not_o more_o remote_a from_o one_o another_o they_o be_v not_o more_o rarefy_v and_o so_o this_o subtle_a matter_n will_v prove_v as_o dense_a as_o any_o other_o matter_n thus_o far_o the_o learned_a frenchman_n of_o which_o the_o sum_n be_v this_o no_o rarefaction_n without_o

be_v the_o least_o of_o all_o capable_a as_o be_v the_o most_o rarefy_a so_o that_o there_o can_v be_v no_o rarefaction_n without_o a_o vacuum_n hither_o may_v be_v refer_v two_o instance_n the_o one_o of_o rarefaction_n and_o the_o other_o of_o condensation_n both_o which_o do_v strong_o plead_v for_o a_o vacuum_n namely_o the_o torricellian_a experiment_n and_o that_o of_o a_o windgun_n as_o

empty_a for_o whilst_o the_o mercury_n be_v a_o pour_v in_o at_o first_o some_o small_a bubble_n will_v still_o escape_v together_o with_o it_o and_o when_o the_o tube_n be_v invert_v and_o the_o
