Brewer's: Dum Vivimus, Vivamus
(Latin). While we live, let us enjoy life. The motto of Dr. Doddridge's coat of arms, which he converted into the subjoined epigram —
`Live, while you live,' the epicure would say, `And seize the pleasures of the present day.' `Live, while you live,' the sacred preacher cries, `And give to God each moment as it flies.' Lord, in my views let each united be; I live in pleasure, when I live to thee.
