symptoms, such as diarrhoea, anaemia, intermittent fever, restlessness, irritability and convulsions are attributed to these worms. The treatment is the administration of santonin, followed by a purgative.
The events of the three years from1820-1823were the beginning of a series of convulsions which lasted till 1874.
Small doses increase the sensibility of touch, sight and hearing; large doses cause twitching of the muscles and difficulty in swallowing; while in overdose violent convulsions are produced.
The patient is then seized with violent convulsions of a tetanic character; the arms are stretched out, respiration impeded, the muscles are rigid, the body is thrown into opisthotonos, i.e.
it is the same atua or spirit which will at times enter not the image but the priest himself, throw him into convulsions and deliver oracles through him."
