feet by the equal development of the cartilage throughout 

 the whole extent of the margin,, it would have covered fully 

 one-third of the whole ear. Two cases have been commu- 

 nicated to me, one in North America and the other in 

 England, in which the upper margin is not at all folded 

 inward, but is pointed, so that it closely resembles the 

 pointed ear of an ordinary quadruped in outline. In one 

 of these cases, which was that of a young child, the father 

 compared the ear with the drawing which I have given* of

the ear of a monkey, the Cynopitliecus niger, and says that 

 their outlines are closely similar. If, in these two cases, 

 the margin had been folded inward in the normal manner, 

 an inward projection must have been formed. I may add 

 that in two other cases the outline still remains somewhat 

 pointed, although the margin of the upper part of the ear 

 is normally folded inward in one of them, however, very 

 narrowly. The above wood-cut (Fig. 3) is an accurate 

 copy of a photograph of the foetus of an orang (kindly sent 

 me by Dr. Nitsche), in which it may be seen how different 

 the pointed outline of the ear is at this period from its 

 adult condition, when it bears a close general resemblance
