Prayer to St. Albert the Great O God our Father, | Fountain and Origin of all wisdom, | you made the bishop St. Albert | great in harmonizing human wisdom | with divine faith; | grant, | we beseech you, | that adhering to his magisterial teaching, | and through the advance of the sciences, | we may come to a deeper knowledge | and love of you, | per scientiam ad Dominum. | We ask the Blessed Mother Mary | to intercede on our behalf | to bring us closer to her Son Jesus | along with St. Albert the Great, | our patron saint. Amen. St. Albert the Great, | Patron Saint of the College of Science, / pray for us! 1 METHODS OF CHEMICAL ANALYSIS 2 F. Sevilla III / J.H.
