Note 92 — THE PART PLAYED BY ACCIDENT IN INVENTION AND DISCOVERY.[81]
Thomas J. (Thomas Joseph) McCormack translation
"Crescunt disciplinae lente tardeque; per varios errores sero pervenitur ad veritatem. Omnia praeparata esse debent diuturno et assiduo labore ad introitum veritatis novae. Jam illa certo temporis momento divina quadam necessitate coacta emerget."
Quoted by Simony, In ein ringförmiges Band einen Knoten zu machen, Vienna, 1881, p. 41.
