54 Daruin- Wallace Celebration. 



auspicious occasion of the special meeting to commemorate 

 the fiftieth anniversary of the reading of the joint essay, " On 

 the Tendency of Species to form Varieties, and on the 

 Perpetuation' of Varieties and Species by natural means of

 on an event to which the scientific advances of fifty years 

 are largely due.
