The third part has for its object a study of the hereditary 
transmission of the floral anomalies of the Maize. His experi-

The great musica of the new forms were obtained from a

author has afforded evidence of the mutational character of the 
origin of this plant’s descendants. His final conclusion is that 
severe and violent mu ailablons constitute a general and convenient 
method of inducing mutability in groups of plants which have 
hitherto been perfectly stable.
