some_o of_o the_o great_a operation_n in_o the_o universe_n and_o as_o in_o the_o history_n of_o the_o creation_n we_o have_v a_o account_n of_o the_o production_n of_o light_n immediate_o after_o

be_v nothing_o but_o a_o great_a number_n of_o single_a parcel_n of_o the_o burn_a body_n raise_v up_o in_o the_o particle_n of_o smoke_n this_o will_v appear_v evident_a if_o we_o consider_v the_o
