 DIADELPHIA. 



' Then names are good, for how, without their aid 

 Is knowledge gained by man, to man conveyed ? 

 But from that source, shall all our pleasure flow ? 

 Shall all our knowledge be, these names to know ? 

 Then he with memory blest, shall bear away 

 The palm from GREW, and MIDDLETON, and RAY : 

 No ! let us rather seek in grove and field, 

 What food for wonder, what for use they yield ; 

 Some just remark, from Nature's people bring, 

 And some new source of homage for her King."
