is held in abeyance, when this power is permanently withdrawn by death, the drug no longer affects the individual cells. The contraction or expansion ceases almost at once." The Chemist cleared a space before him on the table. "In a well-managed club like this," he said, "there should be no flies, but I see several around. Do you suppose we can catch one of them?"
