He also smiled maliciously in the presence of certain physical theories and considered visionary, if not actually insane, the Jesuit Secchi, to whom he imputed the making of triangulations on the host as a result of his astronomical mania, for which reason it was said that he had been forbidden to celebrate mass. Many persons also noticed in him some aversion to the sciences that he taught, but these vagaries were trifles, scholarly and religious prejudices that were easily explained, not only by the fact that the physical sciences were eminently practical, of pure observation and deduction, while his forte was philosophy, purely speculative, of abstraction and induction, but also because, like any good Dominican, jealous of the fame of his order, he could hardly feel any affection for a science in which none of his brethren had excelled—he was the first who did not accept the chemistry of St. Thomas Aquinas—and in which so much renown had been acquired by hostile, or rather, let us say, rival orders. This was the professor who that morning called the roll and directed many of the students to recite the lesson from memory, word for word. The phonographs got into operation, some well, some ill, some stammering, and received their grades. He who recited without an error earned a good mark and he who made more than three mistakes a bad mark. A fat boy with a sleepy face and hair as stiff and hard as the bristles of a brush yawned until he seemed to be about to dislocate his jaws, and stretched himself with his arms extended as though he were in his bed. The professor saw this and wished to startle him. “Eh, there, sleepy-head! What’s this?

This question, instead of offending the class, amused them, and many laughed—it was a daily occurrence. But the sleeper did not laugh; he arose with a bound, rubbed his eyes, and, as though a steam-engine were turning the phonograph, began to recite. “The name of mirror is applied to all polished surfaces intended to produce by the reflection of light the images of the objects placed before said surfaces. From the substances that form these surfaces, they are divided into metallic mirrors and glass mirrors—”
