 arrangement, is due to Swammerdam, but in many 

 other respects Ray has improved on the method of 

 his illustrious cotemporary. He has indicated and 

 characterized several natural groups with great accu-

 without influence in leading to the present improved 

 state of entomological science. Of the imperfec-

 aware than himself. He laments especially the in- 

 accuracy of that part of it relating to flies, and ex* 

 presses a hope that he should soon be able to fur-

 January 1 705. He was buried in the church-yard 

 of his native parish, where a monument was some 

 time afterwards erected to his memory, by the care 

 of Bishop Compton, and others of his friends. It
