From Alexander Agassiz 4 March 1872
Summary
Thanks for new [6th] edition of Origin.
Is working on Echini.
The more material he gets the less easy it is to diagnose a genus or species. Has little doubt that "classification is nothing but the most arbitrary convenient tool, depending upon the material at our command at a special time".
