The effect of N-methyl-formimino-methylester on the neural olfactory threshold in albino mice

The effects of N-methyl-formimino-methylester were studied in albino mice. Very short exposure (0.5 and 1 s) to the concentrated vapour led to an increase of the neural olfactory threshold to geraniol by a factor of 10(5)-10(7). There was a slow recovery of the olfactory sensitivity and after about 40 days the threshold values returned to normal.
