Gustatory Sensation 
(3) In order that introspection may not be influenced by an 
odour sensed in the act of inspiration. O's nostrils must be very 
tightly plugged, for the same reason. 
(4) Yes. The name of the stimulus would bring a host of 
associations with it, and a pure experiment would then be 
impossible. 
Results. — The following results maybe taken as typical: 
Solution. Taste reactions of a single papilla, on different days. 
Tar 
(1) Sharp, salty taste ; (2) Salty. 
Anise 
(1) Very sharp; (2) Sour, with sharp burn. 
Alcohol 
(1) Salt and bitter ; (2) Salt. 
Lemon 
(1) Burns: sour or salt; (2) Sharp burn. 
Wintergreen 
(1) Sweet; (2) Sharp taste. 
Alum 
(1) Very slightly salt ; (2) Nothing. 
Bitter Almond 
(1) Bitter: burns; (2) «-Bitter: burns. 
Cherry 
(1) Sweet; (2) Sweet. 
Peach 
(I) ? Cold; (2) Cold. 
Epsom salts 
(1) Salty; (2) Burns. 
Orange 
(1) Sweet; (2) Nothing. 
Sarsaparilla 
(1) Sour, and slightly bitter ; (2) Bitter. 
Pineapple 
(1) Sweet; {2) Sweet. 
Etc., etc. 
EXPERIMENT XVI 
§ 29. Taste Contrasts. Cautions not noted in the Text. — 
‘Strong’ and ‘weak,’ as applied to taste solutions, are doubly 
relative terms. (1) Individuals differ. Thus, if the 30 °Jo sugar 
solution give no sensation beyond a ‘ sharp burn,’ it will plainly 
be necessary to reduce the strength of the standard sweet. 
(2) Practice makes a great difference. Thus, in the early stages 
of taste-work, a salt solution of 2 % sat. sol. may be subliminal. — 
The Instructor must not expect, then, that the numerical results 
of this experiment will show any great uniformity, as between 
different students. 
O knows the quality of the standard and of the weaker solu¬ 
tions, but should not know whether one of the weaker solutions 
or merely water is to be expected in a given case.
