the_o several_a body_n of_o light_n there_o be_v several_a property_n tincture_n and_o power_n and_o that_o as_o one_o star_n differ_v from_o another_o in_o glory_n according_a to_o the_o apostle_n so_o one_o star_n and_o one_o planet_n differ_v from_o another_o in_o its_o virtue_n in_o its_o colour_n in_o its_o tincture_n and_o in_o its_o property_n and_o consequent_o that_o those_o eminent_a

6._o last_o as_o the_o sunshining_a on_o the_o rest_n of_o the_o planet_n do_v not_o as_o we_o say_v only_o bare_o illuminate_v their_o body_n but_o beside_o this_o through_o the_o power_n virtue_n
