5. "The atavists, as well as the selected individuals, produce 

 fasciated offspring, and often in proportions very Kttle lower 

 than those in which the selected individuals produce them." 



6. "Between the broadened specimens and the atavists there is 

 no essential or fundamental difference, in spite of the great 

 difference in their external forms." 



7. Fasciation is due to some internal hereditary quality, which 

 though often latent, becomes active in response to external 

 conditions. Its wide distribution causes one to assume that 

 it arose in some common ancestor of the forms which now 

 possess it. Hence, phylogeuetically, it must be very old. 



8. Poor races and rich races both may be strengthened or weakened 

 by selection and treatment, but the limits between races are 

 never transgressed. A poor race cannot become a rich one 

 through selection. The external conditions being the same, the 

 hereditary factor must be variable. 



The deVriesian conception of eversporting hereditary characters has 

 burdened the science of genetics with an extremely complex inter- 

 pretation of a set of facts that may be given a much clearer and simpler 

 explanation, and certainly more in accord with the modern strict use 

 of the term heredity. De Vries has urged the need of much more 

 research upon anomalies, and gives his results and conclusions rather 

 as suggestions than unquestionable facts. Further discussion of ever- 

 sporting races is given at the conclusion of this review. 



b) Inherited (germinal) form of fasciation. 



Pisum sativum iimhellatum Mill., Celosia cristata, Nicotiana tahacum 

 fasciata, and some races of Zea mays L. are well known examples of 

 hereditary fasciated races. With the exception of Nicotiana, nothing 

 is known concerning the manner in which they originated or the 

 genetic character of their immediate parents. Numerous observers vouch 

 for the absolute constancy in the transmission of this character by seed. 

 Pisum s. umbellatmn is figured in Gerarde's Herball as a separate 

 species. Lynch, (1900) Körnicke and Rimpau have grown this race 

 for a number of years, and all three regard it as perfectly constant in 

 its transmission of the fasciated character. My own observations have 

 led me to adopt the same view. Goebel grew Celosia cristata, and 

 found, contrary to de Yries that it was absolutely constant as regards 

 fasciation.
