Fig. 1 The basal surface of the tectorial membrane from the left cochlea of 

 the adult hog drawn with the coil opened slightly to obviate the overlapping of 

 its edges existing in its natural coil in the cochlea. Drawing made from several 

 teased out membranes, some whole but slightly damaged in places, others broken 

 in removal and the pieces mounted in their order on the slide.
