This is in accordance with Harvey’s text—“Maturescere profectum salutis.” Grabe, however, reads, “Maturescere prefectum salutis;” making this equivalent to “ad prefectam salutem.” In most mss. “profectum” and “prefectum” would be written alike. The same word (“profectus”) occurs again almost immediately, with an evident reference to and comparison with this clause.
