The memorials he has left on questions of the greatest difficulty are useful and interesting to study, because of the method of work they reveal. It is exactly the method which our old professors of rhetoric used to teach for the orderly arrangement of a French dissertation or an historical essay. The principal and fundamental fact is noted down about the middle of the left-hand page, with a large bracket embracing sub-divisions; each of these sub-divisions is in turn accompanied by a bracket embracing sub-divisions of these sub-divisions; and so on to the end of the right-hand page, which is filled from top to bottom with minute and close writing: there you have a multitude of slight facts following one another in methodical order, all focussing on the principal fact, found, as we have said, in the middle of the left-hand page. There is no college student but has built up his schemes for French essays on this model. But there is no question, in La Reynie's portfolios, of rhetorical dissertations or Latin compositions; he deals there with irrevocable sentences about to be pronounced 'on the flesh and blood of men,' to use his own phrase. And if we go from these bracketed plans to the memoirs and reports to which they guided the magistrate's thought, we find ourselves in possession of marvels of clear thinking and judging. During the long poison case, La Reynie showed himself indefatigable in work. He had no other concern than right and the triumph of justice. And in proportion as the number of criminals increased, and the greatest names in the French nobility and Parlement were found to be compromised by his inquiries--in proportion as relatives, friends, all who feared for themselves, and nobility and Parlement fearing for their honour and their privileges, were up in arms against him, his courage grew, his activity redoubled; he pushed on his inquiries, urging the king, urging the ministers, demanding new warrants, fresh arrests, seeking permission to extend his formidable investigations over an ever-widening circle. Sorceresses and magicians thronged about the royal Court like swarms of wasps about a hive of honey. In this monstrous hive were concentrated the wealth and honours which awoke and stimulated the ambitions and passions in which the sorceresses found their booty.
