Fig. 46.— Diagrams to illustrate the direction taken by the 

 Laminae at different parts of the Foot, as seen in Vertical 

 Section. 



In the top figure the section is made through the toe of the foot : 

 a, being part of the pedal bone ; b, the horny wall ; c, the laminae, 

 which are practically straight, the weight being imposed from 

 top to bottom in their length. The middle figure is a vertical 

 section just behind the point of the frog : the lamina?, c, give the 

 appearance of being placed above one another ; they are rather 

 more obliquely placed than is shown in the drawing. The lower 

 figure is a vertical section through the posterior part of the foot : 

 a, being the lateral cartilage, and c, the laminae, which should 

 slope rather more than is shown in the figure : it will be observed 

 that the lamina?, as in the previous figure, are placed one above 

 the other — this arrangement gives strength.
