The authors made an experiment for the purpose of examining the active principle of the so- called venous sense of smell. The experiment was carried out as follows: 1) Healthy presons having normal sense of smell were injected with 10mg of alinamin (Vita minB1) into the cubital vein. After the injection, resiratory action was restrained. Then, air was only inhalated through the nostrils passively or actively. No positive olfactory response could be elicited in the above procedure. 2) Total laryngectomized patients were next examined. When these patients were inhibited to breathe through the oral cavity, they had no positive olfactory response. 3) Positive olfcctory response could be elicited only perioral respiratory action, that is, in case air was inhalated from the choana to the nosttrils through the oral cavity, the subjects showed positive response. 4) Furthermore, the saliva lebel of vitamin B1 after the injection was proved to 3 times as much as befor. From the results mentioned above, the authors concluded that there exist no venous sense of smell, and this type of sensation might be designated as taste sense of smell.
