both of us been privy to for many years. On representing 

 this to Mr. Darwin, he gave us permission to make what use 

 we thought proper of his memoir, &c. ; and in adopting our 

 present course, of presenting it to the Linnean Society, we 

 have explained to him that we are not solely considering the 

 relative claims to priority of himself and his friend, but the 

 interests of science generally ; for we feel it to be desirable 

 that views founded on a wide deduction from facts, and 

 matured by years of reflection, should constitute at once a 

 goal from which others may start, and that, while the scientific 

 world is waiting for the appearance of Mr. Darwin's complete 

 work, some of the leading results of his labours, as well as 

 those of his able correspondent, should together be laid before 

 the public." 



The title of the joint paper was " On the Tendency 

 of Species to form Varieties ; and on the Perpetuation 

 of Varieties and Species by Natural Means of Selec- 

 tion." It was read July 1st, 1858.
