grinding the nosestone
It is well known that gastric pains occur especially often in those who masturbate. According to a personal communication made to me by Wilhelm Fliess, it is precisely gastralgias of this character which can be interrupted by an application of cocaine to the "gastric spot" discovered by him in the nose, and which can be cured by the cauterization of the same spot.
