We can picture the youthful teacher--he was but twenty-eight--among students in a university which they themselves controlled--some of them perhaps the very men who five years before had elected him--at the last meeting with his class, perhaps giving a final demonstration of the woodcuts, which were of an accuracy and beauty never seen before by students' eyes, and reading his introduction.

There would be sad hearts at the parting, for never had anyone taught anatomy as he had taught it--no one had ever known anatomy as he knew it.

But the strong, confident look was on his face and with the courage of youth and sure of the future, he would picture a happy return to attack new and untried problems.

Little did he dream that his happy days as student and teacher were finished, that his work as an anatomist was over, that the most brilliant and epoch-making part of his career as a professor was a thing of the past.

A year or more was spent at Basel with his friend Oporinus supervising the printing of the great work, which appeared in 1543 with the title "De Humani Corporis Fabrica." The worth of a book, as of a man, must be judged by results, and, so judged, the "Fabrica" is one of the great books of the world, and would come in any century of volumes which embraced the richest harvest of the human mind.
