rapidly but grown slowly. Helen has been delayed in everything 

 except size, has metamorphosed slowl}^ but has grown rapidly. 

 Mar}^ had a Hyper ear at birth, Helen had a Hj^po ear at birth. 

 Mary's nose was long at birth and rapidly approached the 

 Hyper form, Helen's was short at birth and has retained the 

 Hyper form. Mary's head elongated rapidly. Helen's elongated 

 slowly. Mary crawled, climbed, stood alone, walked and talked 

 earlier than Helen. Mary's teeth are small and apparently 

 immature, Helen's are large and perfect. Mary is Hyper with 

 rapid metamorphosis and slow growth, and Helen is Hypo with 

 slow metamorphosis and rapid growth. I shall watch with 

 interest their future development. 



The Meso ear has a prominent or intermediate helix, lobule and 

 anthelix, and a depressed or intermediate tragus and antitragus. 

 The ear is nearlj^ flat, the bowl is shallow, and the helix is not 

 so much rolled in as in the Hypo ear. The Meso ear type is 

 somewhat intermediate between the Hypo and Hj^per types and 

 it may be considered as the fundamental or generahzed type of 

 ear from which the Hypo and Hyper type have evolved in differ- 

 ent directions. 



The Meso ear is usually large and thick and heavy. The helix 

 and anthelix being equally prominent a double roll is formed near 

 the dorsal margin of the ear. The lobule and lower helix turn 

 out from the head in the form of a shelf, and not to the same 

 extent as in the Hypo ear, and the shelf, instead of being horizon- 

 tal as in the Hypo ear, has a gentle slope forw^ard or maj^ be 

 precipitous. At times the ear is almost flat, and quadrangular 

 in shape. 



Hyper-phylo-morph: An ear that is more or less intermediate 

 between the Hyper and Meso types occurs frequently. The 

 Hyper characteristics predominate although in each ear some 

 Meso characteristics may be seen. This is a male ear type 

 because very few appear among the women. 



It may be well to determine the relation of the form of nose, 

 head and face to the type of ear. 



Nasal index and ear type: The noses of the persons with 

 Hypo ears are relatively broader than those with Hyper ears
