Allow me, dear Prof. Owen, to send to you for kind identification specimens of the insect, which produces the Melitose (or Eucalyptus Manna) on Euc. viminalis . Though much controversy about the origin of this saccharine crumblike substance has been going on for very many years, I have only this season been able by the help of an Assistant of mine

Let me hope, honored and venerable friend, that this year may again be to you one of unimpaired health and scientific triumphs, and that providence will grant you yet many other years for your luminous career & worldly happiness.
