hard floors (bamboo or other material) with only the petate or a small 

 hard pillow between the head and the floor. This is the coolest way to 

 sleep in the tropics, the soft pillow being particularly hot and oppressive. 

 "\¥lien the baby is placed npon a petate, in acquiring the habit it normally 

 lies flat upon its back and the head is either straight or turned slightly to 

 one side. After a few months a flat place is formed on that part of the 

 head resting on the petate, and the child then lies on this flat place until 

 the head becomes misshapen and sometimes badly deformed. 



When my daughter was about one or two months old we kept her in a 

 woven bed with only a sheet and a petate beneath her until about the third 

 month when I noticed a small flat place in the occipital region of the head, 

 after which we used a small pillow and the head soon resumed its normal 

 dorsal rotundity. 



This matter is a subject of great interest and may Idc one of vital im- 

 portance because .such deformities may result in impaired mental ability 

 by undue pressure and distortion of the brain when it is developing most 

 rapidly. We would therefore suggest that a study of the school children 

 be made by the teachers in the public schools, using the cephalograph ( 7 ) 

 originated by Doctor Bean, one of which is owned by the Bureau of 

 Educa,tion. The teachers are probably the only ones who can control the 

 children sufficiently without the aid of the parents so that their head 

 outlines can be made. Eecords should be kept showing the physical and 

 mental condition of the child and from time to time the head oiltlines 

 should be made, the parents having been instructed previously about the 

 piroper head rest for their children. The teachers may be able to induce 

 the youngest children also to have their head outlines made in order that 

 the study may begin in the cradle, or rather on the petate, at which time 

 the most good can be accomplished. 



If the deformed condition of infancy persists during the adult life of 

 the individual, then otherwise dolichocephalic or mesocephalic heads be- 

 come mesoceplialic or brachycephalic, and a part at least of the brachy- 

 cephally and mffsocephally of the Orient is not natural. 



The vertical occiput and the front honibe may be only deformities and 

 not racial or true morphologic characteristics. For this reason, I believe 

 the cephalic index is not the best differential factor although it still may 

 be of some service and should not be discarded entirely, but relegated to 

 a subordinate position in racial anatomy. 



Forty-two heads of Taytayans give evidence of dorsal flattening to 

 a noticeable degree, and among these greatly distorted heads are in- 

 cluded all those of the Primitives, 6 of the Australoid, 1 B. B. B., 

 ] Adriatic, 6 Iberian Blends (Alpine), 5 Primitive Blends (flg. 10), 

 3 Adriatic Blends, and the remainder are Blends of various sorts. Ii) 

 connection with the ear type, it is of interest to note that 13 of the 42 

 flat heads had ears of the odd type, although 16 odd type ears were not
