But the cup of the iniquities of his oppressors was now full, and their hour of retribution was at hand. The blow dealt against them was not so severe as injured justice might have required, but it was dealt with an ignominious scorn that made compensation for its want of severity. There were at that time many men of high spirit and great attainments in the Scottish bar. They knew that the age they belonged to was one, in which the safety of the public liberties was intimately allied with the independence of the bar. It was not an uncommon practice for a few of the ablest and most popular advocates to unite together in vindication of the victim of some formidable system of oppression; and, fortunately for Williamson, his case attracted their generous interest. Andrew Crosbie, the prototype of Scott's Pleydell, threw his whole energies, and they were not small, into this cause. The pleadings at our bar at that time were full of philosophy, general declamation, and poetry; and we have before us some papers from Crosbie's pen which are brilliant and pleasing specimens of this class of forensic rhetoric. At the present day the rhetoric of the law appeals only to the jury, and in the shape of vocal oratory. In the days of our grandfathers it was addressed to the learned bench, and was embodied in carefully prepared written pleadings. The intellectual rank of the audience to be influenced, and the medium of communication, would thus naturally invest the pleadings of these old lawyers with a literary turn, not equalled in the corresponding productions of this age. So we find that Crosbie bursts open the case with these well-turned periods:-- "That liberty which the constitution of this country considers as its favourite object, is the result of the due equipoise which our law has established between the authority of magistrates and the rights of the people. As the relative duties of society must be enforced by the magistrate, and compliance with the laws exacted from the citizens by means of his authority, all the power that is necessary for these salutary purposes is bestowed upon him; and, in the due execution of it, he is not only entitled to the protection of the law, but is an object of its veneration. Yet the same principles that have thus armed him with authority, for the benefit of society, have wisely imposed on him a restraint from abusing it."
