92 PHILOSOPHICAL NOTES ON 



" Life is coutiuuous and not periodically interrupted ; ever since its first 

 appearance upon the earth in the lowest organisms it has continued without 

 break ; the forms in which it is manifested have alone undergone change. 

 Every individual alive to-da}' — even the very highest — is to be derived in an 

 unbrokfcHi line from the first and lowest." — Weisraaun, " On Heredity," 

 p. 159.
