If the herd over which a usufruct has been established perishes entirely by accident or disease and through no fault of the usufructuary, the usufructuary is liable to the owner only for an account of the hides, or their estimated value at the date of restitution.
If the herd does not perish entirely, the usufructuary is liable to replace, up to the amount of the growth, the heads of the animals that have perished.
