 Using brain wave as an index of stimulation the threshold value of the sense of smell was sought. The subjects of this test composed of 20 individuals whose sense of smell was normal; the object of smell consisted of strawberry essence diluted to various strengths. The response was 10% when the dilution was 6400 times; 45% at 1600 times; 55% at 800 and 200 times alike; 65% at 50 times; 70% when there were no dilution. Changes in respiration curves were recognised in 30% of the number examined.
