Yet, to be exact, we will say that in this laboratory are held the classes of thirty or forty advanced students, under the direction of an instructor who performs his duties well enough, but as the greater part of these students come from the Ateneo of the Jesuits, where science is taught practically in the laboratory itself, its utility does not come to be so great as it would be if it could be utilized by the two hundred and fifty who pay their matriculation fees, buy their books, memorize them, and waste a year to know nothing afterwards. As a result, with the exception of some rare usher or janitor who has had charge of the museum for years, no one has ever been known to get any advantage from the lessons memorized with so great effort. But let us return to the class. The professor was a young Dominican, who had filled several chairs in San Juan de Letran with zeal and good repute. He had the reputation of being a great logician as well as a profound philosopher, and was one of the most promising in his clique. His elders treated him with consideration, while the younger men envied him, for there were also cliques among them. This was the third year of his professorship and, although the first in which he had taught physics and chemistry, he already passed for a sage, not only with the complaisant students but also among the other nomadic professors. Padre Millon did not belong to the common crowd who each year change their subject in order to acquire scientific knowledge, students among other students, with the difference only that they follow a single course, that they quiz instead of being quizzed, that they have a better knowledge of Castilian, and that they are not examined at the completion of the course. Padre Millon went deeply into science, knew the physics of Aristotle and Padre Amat, read carefully his “Ramos,” and sometimes glanced at “Ganot.” With all that, he would often shake his head with an air of doubt, as he smiled and murmured: “transeat.” In regard to chemistry, no common knowledge was attributed to him after he had taken as a premise the statement of St. Thomas that water is a mixture and proved plainly that the Angelic Doctor had long forestalled Berzelius, Gay-Lussac, Bunsen, and other more or less presumptuous materialists. Moreover, in spite of having been an instructor in geography, he still entertained certain doubts as to the rotundity of the earth and smiled maliciously when its rotation and revolution around the sun were mentioned, as he recited the verses “El mentir de las estrellas Es un cómodo mentir.” [29]
