the lower jaw of a six months' foetus, Meckel's cartilage can readily be 

 seen with the naked eye. The cartilage shows up as a greyish white 

 elevated line along the inner surface of the jaw. The cartilage lies close 

 under the inner aspect of the condyle, and, first of all, runs almost 

 horixontally forwards till it reaches a point below the coronoid process,

here it bends sharply down to the lower border of the bone, and then 

 runs along just inside the lower border of the jaw to terminate in a 

 slight knoli opposite the interval between the canine and lateral 

 incisor teeth (Fig. !.">, II.). From this small knob a delicate ridge 

 nins upwards and inwards, terminating at the symphysis just above 

 the genial tubercle- this ridge seems to indicate the course of that
