'when talking on the subject of prayer [to Johnson on his deathbed], Dr. Brocklesby repeated from Juvenal,--
"Orandum est, ut sit mens sana in corpore sano",
and so on to the end of the tenth satire; but in running it quickly over, he happened, in the line,
"Qui spatium vitae; extremum inter munera ponat",
to pronounce supremum for extremum; at which Johnson's critical ear instantly took offence, and discoursing vehemently on the unmetrical effect of such a lapse, he shewed himself as full as ever of the spirit of the grammarian'.
