 myself on being so circumstanced, since I am thus enabled to express 

 my respect for your high scientific attainments and for those original 

 observd,tions and writings which have appeared during the long period 

 that has elapsed since I first enjoyed the privilege of friendly inter-

 and my official connexion with you. 



I am, 

 Your Grace's faithful and obedient servant,
