MEMOIR OF PLINY.

 prove, may justly be ranked. - It is with extreme 

 willingness, therefore, that I execute your commands ; 

 and should indeed have claimed the task, if you had 

 not enjoined it. He was at that time with the fleet 

 under his command at Misenum. On the 24th of 

 August, about one in the afternoon, my mother de-
