A ring for sampling of one gram of feces was devised to substitute for weighing feces for the fecal egg count of helminths. It was 12mm in diameter and 8.84mm in depth, its space being one ml. A handle 100mm in lenth was attached to the ring. Fecal consistency was classified into solid, soft, diarrheal and watery diarrheal. When a fecal mass was kept in the ring, it was regarded as solid or soft. Soft feces were not released from the ring in to water by gentle shaking, but soft feces were easily. Feces that were not kept in the ring were rgearded as diarrheal or watery diarrheal. Watery diarrheal feces could be poured into the ring which was placed on paraffin paper, but diarrheal feces could not. Mean weight of solid, soft, diarrheal and watery diarrheal feces which were measured by the ring was 1.11, 1.16, 1.07 and 1.06g, respectively. They were close to 1.0g. There fore, the ring was regarded as useful for the measurement of one gram feces in practical fecal examinations of helminth and the objective judgment of fecal consistency.
