that_o the_o moisture_n may_v oose_v gentle_o out_o the_o body_n will_v bend_v still_o more_o and_o more_o as_o their_o absence_n give_v it_o leave_v but_o if_o the_o motion_n wrought_v in_o it_o be_v

by_o any_o mean_n to_o slide_v they_o over_o as_o for_o example_n let_v we_o borrow_v of_o gallileus_n the_o proportion_n of_o weight_n between_o water_n and_o air_n he_o 18._o show_v we_o how_o the_o

which_o two_o never_o miss_v to_o reign_v whenever_o the_o water_n freeze_v and_o both_o of_o they_o argue_v great_a store_n of_o little_a earthy_a dry_a body_n abound_v in_o they_o which_o sweep_v

it_o may_v be_v light_a in_o the_o bulk_n than_o water_n by_o reason_n of_o the_o great_a pore_n cause_v in_o it_o through_o the_o shrink_n up_o of_o the_o part_n of_o water_n together_o which_o

that_o his_o last_o argument_n ground_v upon_o the_o the_o swim_n of_o ice_n in_o water_n have_v no_o more_o force_n then_o if_o he_o will_v prove_v that_o a_o iron_n or_o earthen_a dish_n be_v

and_o thus_o you_o see_v three_o root_n of_o three_o divers_a plant_n all_o in_o the_o same_o plant_n proceed_v by_o natural_a resolution_n from_o one_o primitive_a source_n whereof_o that_o which_o

the_o oily_a part_n be_v fit_a for_o the_o continuance_n and_o solidity_n of_o the_o plant_n for_o we_o see_v that_o viscuosity_n and_o oiliness_n hold_v together_o the_o part_n where_o they_o
