a temptation for the sake of his children, but the world would have lost all the great discoveries with regard to human diseases. It is not unlikely that these would have been made even without Pasteur, There is no doubt, however, that their discovery {320} would have been very much delayed and that as a consequence almost untold human suffering that has been prevented would have occurred. It must never be forgotten that such men as Lister and Koch derived their most fertile suggestions from the discoveries made by Pasteur. Pasteur's life may very well be held up, then, as a model to the present and future generations of what the highest ideals of a scientific career can be. Dr. Christian Herter, in the discourse already quoted from, has stated this so well and at the same time has joined with it so felicitously a quotation from Pasteur's advice to young men, that we can find no better way in which to close this consideration of Pasteur's career than by quoting him once more: "To have fought the long battle of life with unwavering constancy to the loftiest ideals of conduct, toiling incessantly without a thought of selfish gain; to have remained unspoiled by success and unembittered by opposition and adversity; to have won from nature some of her most precious and covert secrets, turning them to use for the mitigation of human suffering;--these are proofs of rare qualities of heart and mind. Such full success in life did Louis Pasteur attain, and from the consciousness of good achieved his noble nature found full reward for all his labors. "Of the children whom nature has endowed with splendid gifts there are few whose lives have affected so profoundly and so beneficently the fate of their fellows, few who have earned in equal degree the gratitude and reverence of all civilized men. Although not many can hope to enrich science with new principles, all of us may gain from Pasteur's life the inspiration to cultivate the best that is in us. Let us keep living in our memories the inspiring words which the master spoke on the seventieth anniversary of his birthday:
