marked the regions by red lines and traced these on transparent 
paper. These areas were then measured from the paper. 
Around the fingers he wound strips of paper of a uniform 
width. Other uneven surfaces he covered with gummed paper. 
Although Meru measured several subjects, the results for a 
thirty-six years old man, corpulent, 171 cm. in height, and 
body-weight 78.2 kg., only are given.

Head 80,380 mm?.

Both sides (his own figure) 2,243,490 mm?. 
By pelvic region MrEH means the dermal surface of the 
hips, i. e., the area between a line running along the crest of 
the pelvis and one transversely around the thigh about on a 
level with the ‘uberculum pubicum. ‘This region is innervated 
by lumbar and sacral nerves and is included in the area for the 
the entire leg. 
MeEeEn’s line between the neck region and the trunk region 
runs from the top of the acromion process along the clavicle on 
the ventral surface of the body and on the dorsal surface to 
about the level of the spine of the seventh cervical vertebra. 
Since, however, the nn. supraclaviculares innervate a portion of 
the skin below the clavicle, it is probable that his area for the 
neck region is a trifle too small for the skin innervated by the 
cutaneous nerve fibers in the dorsal spinal roots C. I-IV.
