The consequence is a return of the haemorrhage ; or else the haemorrhage recurs from some other trivial cause, .... and unless care is taken a Vicious Circle forms which may lead to more serious consequences.” 2 Rhinolith. The development of the various forms of calculi occurring in the body is dependent on reciprocal reactions between the primary nucleus and the subjacent mucosa, and the same principle applies to the rhinoliths occasionally met with. The nucleus, whether consisting of a foreign body, of blood or of mucus, becomes encrusted with cal¬ careous matter derived from the nasal secretions, and becomes in turn a source of irritation to the mucosa.
