that_o grant_v and_o the_o parallax_n of_o the_o comet_n unknown_a i_o will_v undertake_v very_o easy_o to_o make_v out_o almost_o any_o hypothesis_n which_o be_v the_o fault_n also_o of_o mr._n

he_o have_v place_v it_o it_o be_v very_o rational_a that_o the_o motion_n of_o it_o at_o first_o if_o cast_v out_o of_o the_o sun_n shall_v be_v very_o swift_a but_o than_o it_o ought_v likewise_o to_o have_v accelerate_a its_o motion_n in_o the_o same_o manner_n in_o its_o return_n back_o to_o it_o again_o which_o it_o do_v not_o in_o his_o hypothesis_n for_o a_o stone_n or_o any_o other_o

it_o almost_o i_o say_v because_o the_o resistance_n of_o the_o air_n do_v so_o far_a impede_fw-la the_o motion_n of_o the_o body_n through_o it_o that_o it_o never_o suffer_v it_o to_o acquire_v the_o same_o degree_n of_o velocity_n with_o which_o it_o be_v first_o shoot_v upward_o this_o be_v sufficient_o evident_a from_o a_o pendulum_n which_o if_o it_o be_v throw_v upward_o and_o be_v

be_v throw_v but_o beside_o in_o his_o hypothesis_n he_o seem_v to_o take_v no_o notice_n at_o all_o of_o the_o latitude_n of_o the_o comet_n which_o seem_v to_o carry_v it_o much_o far_o off_o from_o the_o sun_n when_o he_o suppose_v it_o to_o be_v return_v near_o and_o indeed_o upon_o the_o whole_a his_o hypothesis_n seem_v rather_o a_o product_n of_o chance_n than_o of_o any_o contrivance_n for_o he_o in_o endeavour_v to_o set_v off_o the_o longitude_n of_o the_o comet_n according_a to_o tycho_n table_n and_o to_o trace_v its_o way_n by_o suppose_v the_o earth_n annual_a motion_n make_v
