Census Directors register the existence of a new will creature when the first act of will is performed; they indicate the death of a will creature when the last act of will takes place. The partial emergence of will observed in the reactions of certain of the higher animals does not belong to the domain of the Census Directors. They keep count of nothing but bona fide will creatures, and they are responsive to nothing but will function. Exactly how they register the function of will, we do not know.
