The character in questionis only latent in them, or rather only temporarily invisible;perhaps simply not developed by reason of the absenceof some necessarv external factors. The atavists do not, so to speak, depart from therace, as do those of Oenothera scintillans; the race con- The Inheritance of Fasciations. 491 stitutes a uniforni group of individuals and only differsfrom constant races or true varieties by the extraordi-narily high degree of variability of its distinguishingcharacter. This degree of variability relates not only to thedegree of expansion of the axis, but also to the mannerin which the anomaly is manifested. First we have to
