CUTANEOUS SENSATIONS. 

 BY C. S. SHERRINGTON. 



THE SENSE OF TOUCH Touch-Spots The Adequate Stimulus Weber's Law in 

 respect to Tactual Sensations The Spatial Quality of Touch Theory of 

 "Localising" Power of Touch Projection of Touch Illusions in Tactual 

 Judgments Reaction Time for Touch THE SENSE OF TEMPERATURE "Cold" 

 and "Warmth" as Distinct Species of Sense Distribution of Apparatus for 

 Thermal Sensations in the Skin, etc. The Adequate Stimulus Other Stimuli 

 Paradoxical Sensation of Cold Some Characters of " Cold " and " Warmth 

 Sensations Relation of Thermal Sensation to Pain Influence of Areal Extent 

 of Stimulus upon Intensity The Physiological "Zero-temperature and 

 "Adaptation" The Degree of Projection of Thermal Sensation The Thermal 

 Sense in relation to Thermotaxis The Liminal Difference of Intensity of 

 Stimulus Reaction Time Antagonism of Sensations of "Cold "and "Warmth 

 Paths of Conduction COMMON SENSATION Cutaneous Pains considered in 

 relation to Pain in general Relation of Pain to Intensity of Reaction Quality
