Well, then, it will be remarked that between thebone attached to the membrane of the tympanum andthat which covers \\\q fenestra ovalis, or oval window,as it is termed, there is a fourth bone, the shape some-what of a blacksmiths anvil, and hence called incus. 342 FALLACIES OF DARWINISM. Now attached to the membrane of the tympanuminternally are two exquisite little muscles, one of whichextends and is joined to the minute orbicular bonebetween the stirrup and the anvil, and the other to themallet. Remember that the use of these little musclesis to restrict or modify the vibration caused on thetympanic membra
