Some of the fragrance definitely disappears into your nose.  Otherwise, 
you'd smell nothing.  The question is, Is it replaced at a sufficient 
rate to keep the odor at the same intensity.  Maybe not.  Perhaps I'll have 
some beginning biology students do this in lab.  You'd want a large cross-
section of sniffers, of course.  However, the other thing that can occur is 
that one's nose's nerve cells get "fatigued" or desensitized from 
stimulation and one ceases to smell much.
