work very well. The other apparatus used will be described 
further on.

Extent, 2x3 cms. Dots indicate cold ; circles, heat ; the larger ones 
represent the spots which give a strong reaction ; the smaller, those which 
give a weak one. The top of the map is peripheral, the bottom central. 
The light side is the radial ; the left the ulnar.

the ulnar. 
In the statement of results it will be necessary to give them in 
chronological order to show how far they were independent. 
When first experimenting, a cold brass point, 1 '5 nuns, in diameter, 
was the only instrument used. With this I had found that cold 
was felt in spots, some spots giving an intense sensation, others a 
wreak one ; that the skin between these spots was not sensitive 
to cold ; that the points were differently distributed in different 
parts of the same individual, and in similar parts of different 
individuals ; that they were very small—as shown by the fact that 
unless a spot was carefully marked it could not be easily found 
again, for passing the point even very close to it did not rouse a 
sensation, as a rule ; that they were permanent—once having been 
found they always could be found again ; that they were easily 
exhausted—this being shown by the fact that, when the metal 
point was drawn down the arm and a certain number of points 
were observed, if it was again drawn down immediately, the 
number noticed on the second trip was almost always less than 
on the first, but if some minutes were allowed to elapse between 
the two trips, then the second result was, as a rule, like the first. 
When I had gone thus far, Blix’s paper was received. Blix 
(1), besides noting all the points above mentioned, found similar 
spots for heat, and found that what was true of the cold-spots 
■was true of the heat-spots also, so far as their arrangement and 
distribution were concerned. He noticed also that the arrange¬ 
ment on symmetrical parts was not symmetrical ; that the rela-
