"Quasars forever"
or, more likely given that it was written in 1874:
"like a star for eternity"
Inscription over the stage of Sanders Theater, Harvard University, Cambridge Massachusetts: Qui.Autem.Docti.Fuerint.Fulgerbunt.Quasi.Splendor.Firmamenti
Et.Qui.Ad.Ivustitam.Erudunt.Multos
Quasi.Stellae.In.Perpetuas.Aeternitates
