1. The percentage of diseased moths of silkworms in a lot diminishes gradually as the date of eclosion retards.<br>2. Accordingly, its distribution does not show binomial distribution or POISSON distribution, in many cases.<br>3. The diseased moths of a lot, eclosed on the same day, show binomial distribution, regardless of the date of eclosion.<br>4. Such being the case, a lot is the population of assembly of worms, ranged with the diminishing percentage of pèbrine in accordance with deladed date of eclosion, holding the binomial distribution in each day.<br>5. For this reason, both, the sequential sampling inspection method devised by WALD and the method, ASTM Quality Control of Materials, cannot be used for the sampling inspection of mother moths of eggs, acid treated after chilled, and of eggs, hibernating.<br>6. The sampling of the silkworm mother moth must be the proportionate sampling.<br>7. In the case of common acid treated eggs, when all samples become free from pèbrine after daily sampling inspection, the whole eggs of a lot laid afterwards can be passed safely without inspection.
