RESPONSES TO ODORANTS 69 



reserve the proviso that no other binding mechanism of appreciable 

 capacity be active. Stuiver's (1958) assumption that practically all the 

 odorant molecules striking the mucous surface are trapped indefinitely 

 long seems most applicable to odorants of high aqueous solubility. 



With increase in capacity of any trapping mechanism there should, of 

 course, be an increase in flow dependence for the attainment of a given 

 concentration of odorant molecules at some point within the mucus. The 

 kinetics of stimulus transport to the vomeronasal and trigeminal receptors 

 presents interesting problems for study.
