summarized as nearly as possible in Professor Mackenzie's own words : 

 (i) In a certain proportion of women whose nasal organs are 

 healthy, engorgement of the nasal cavernous tissue occurs with unvary- 

 ing regularity during the menstrual epoch, the swelling of the membrane 

 subsiding with the cessation of the catamenial flow. Pathology also 

 furnishes a variety of cases of analogous nature. The investigations of 

 Flicss would seem to indicate that painful, profuse and irregular men- 

 struation may be temporarily dissipated by the application of cocaine to 

 the nasal mucous membrane, or permanently controlled by cauteriza- 

 tion. According to him, only the inferior turbinated body and the 

 tuberculum septi possess a special relation to the dysmenorrhoeic pains. 

 These two localities he accordingly designates as genital zones (Geni- 

 talstellen). 



(2) The presence of vicarious nasal mestruation. 



(3) The well-known sympathy between the erectile portions of 

 the generative tract and other erectile structures of the body, e. g., the 

 nipples. 



(4) The occasional dependence of phenomena referable to the 

 nose during sexual excitement, e. g., sternutation, epistaxis, occlusion 

 of the nasal passages. 



(5) The occasional dependence of genito-urinary irritation upon 

 affections of the nasal passages. 



(6) Venery and masturbation seems to have a tendency to initiate 

 inflamation of the nasal mucous membrane, or to aggravate existing 

 disease of that structure. 



(7) It is, finally, quite possible that irritation and congestion of 

 the nasal mucous membrane precede, or are the excitants of, the olfac- 

 tory impression that forms the connecting link between the sense of 

 smell and erethism of the reproductive organs exhibited in the lower 

 animals and in those individuals whose amorous propensities are aroused 

 by certain odors that emanante from the person of the opposite sex.
