But such popularity among the students was apt to beget a different feeling among the professors; it especially roused Mr. Vilant, the gentleman as whose substitute Chalmers had been acting. Mr. Vilant, it appeared, had been granting certificates without communication with his assistant--a grievous offence in his eyes. Accordingly, at the public examination of his classes at the end of the session, Chalmers broke out into a severe invective against him, and delivered a long, sarcastic speech in condemnation of his conduct. The professors knew not how to look, but at last the Principal brought the speech of Chalmers to an end, and he proceeded with his examination as if nothing had happened.
His capacity of combining strong feeling in one direction with perfect self-control in every other was very remarkable. Many years afterwards, when expressing his views with extraordinary energy in the General Assembly on the question that led to the Disruption, he was interrupted by a layman, who remarked that they were all pleased to hear him, excited though he was, but that there were limits, etc., etc. 'Excited!' exclaimed Chalmers, in great astonishment; 'does the gentleman say that I am excited? I am as cool as an algebraic problem.' His head was in no degree disturbed by the vehemence of his heart.
A short time had to elapse between the close of the session and his ordination as minister of Kilmany, which Mr. Chalmers devoted to a visit to Edinburgh. His father was disappointed and mortified that on the eve of entering on so solemn a profession, he did not put the interval to use at home in the way of earnest meditation and prayer. For that, however, the son did not see the slightest necessity. He deemed himself already sufficiently prepared for his duties, with the nature of which he was well acquainted. In this strain he wrote to his father, adhering to his plan. A few years later he would have felt most differently, and, ashamed of his carelessness, he would have most cordially fallen in with all that his father had written.
