although it may be an approximation to the truth, it

The object of this work is to present a new hypoth- 

 esis which will be seen to bear a close resemblance to 

 the one which has been advocated by Darwin, although 

 careful examination will show that it is in reality very 

 different. I hope to show that it is not open to the ob- 

 jections which are urged against the pangenesis hypoth- 

 esis, while it contains all the features which give value 

 to the latter.
