220 INITIATIVE IN EVOLUTION 



Schafer says : " An area of the dorsum of the distal phalanx 

 of a finger contains about seven times as many touch 

 spots as an equal area between the shoulders. Regions 

 poor in touch spots are the flexor surface of the upper 

 arm, the upper third of the thigh, the leg above the inner 

 malleolus, the neck, and in general the skin over sub- 

 cutaneous surfaces of bone." 1 



Table IV. — Distribution of Cold and Warmth Sensations. 



The Scale includes twelve grades of sensation in cold, and eight 

 in warmth sensations, and commences with the regions 

 which yield the maximal intensity of sensation. 

 Cold Sensations. 



1. Tips of fingers and toes, malleoli, ankle. 



2. Other regions of digits, tip of nose, olecranon. 



3. Chin, palm, gums, glabella (a small central area just above 



bridge of nose). 



4. Occiput, patella, wrist. 



5. Clavicle, neck, forehead, tongue. 



6. Buttock, upper eyelid. 



7. Lower eyelid, popliteal space, sole, cheek. 



8. Inner aspect of thigh, arm above elbow. 



9. Intercostal spaces along region of axillary line. 



10. Areola of mamma. 



11. Nipple, flank. 



12. Certain areas of loins and abdomen. 



Warmth Sensations. 

 Absent from lower gums, mucosa of cheek at second lower 

 molar and cornea. 



1. Tips of fingers and toes, cavity of mouth, conjunctiva, 



patella. 



2 . Remaining surfaces of digits, middle of forehead, olecranon. 



3. Glabella, chin, clavicle. 



4. Palm, buttock, popliteal space. 



5. Neck. 



6. Back. 



7. Lower eyelid, cheek. 



8. Nipple, loin. 



Table V. — Distribution of Cold and Warmth Spots. 



By stimulation of cold or warmth spots there is shown, not 

 only the quality and quantity of the stimulus, but the 

 locality. When punctiform stimuli are applied to pairs of
