THE human mind enjoys to-day an enormous possession of ideas, 

 heaped up, selected, sifted out by the centuries. The multitude 

 of men have disappeared without contributing to this store a jot. 

 Those who have had the fortune to add something, to leave some- 

 thing, should have their part in the glory and the recognition which 

 is their due.
