"Who has won more fame in the field of chemistry than this author? Who can boast of more happy successes or more excellent results? He worked night and day, never letting go of his object, nature; through this science he improved our life and put others share in what he had discovered with superhuman assiduity, at his own peril, at his own expense -- the first, the only one to achieve such happy results. But how devout was this guileless soul at all times! How pure his heart in serving God! He gave us generous love to one and all, and pious veneration to the Divine tterances, distinguishing in the most prudent manner between the principles of religion and the whole field of natural and chemical science. I refer to the writings of this man, which he published for the great good of human race; treatises on the style that prevails in the Holy Scriptures, on the love of God, on the design of God, the Creator, on the duty of gratitude and reverence, to be rendered by man to the Almighty God, his Redeemer."
