Why, reasoned Beck & Miles, should the numan nose not do the same...
...which are normally cooler than they are. Therefore the cells radiate heat waves across the air stream. Beck & Miles theorized that when pure air is passing through the nostrils, the cells give no signal; they are getting rid of their heat at the standard rate.
