What subject does he take? Melancholy, his own individual mood; and he takes it like a schoolman. None of St. Thomas Aquinas's treatises is more regularly constructed than his. This torrent of erudition flows in geometrically planned channels, turning off at right angles without deviating by a line. At the head of every part you will find a synoptical and analytical table, with hyphens, brackets, each division begetting its subdivisions, each subdivision its sections, each section its subsections: of the malady in general, of melancholy in particular, of its nature, its seat, its varieties, causes, symptoms, prognosis; of its cure by permissible means, by forbidden means, by dietetic means, by pharmaceutical means. After the scholastic process, he descends from the general to the particular, and disposes each emotion and idea in its labelled case. In this framework, supplied by the Middle Ages, he heaps up the whole, like a man of the Renaissance--the literary description of passions and the medical description of madness, details of the hospital with a satire on human follies, physiological treatises side by side with personal confidences, the recipes of the apothecary with moral counsels, remarks on love with the history of evacuations. The discrimination of ideas has not yet been effected; doctor and poet, man of letters and savant, he is all at once; for want of dams, ideas pour like different liquids into the same vat, with strange spluttering and bubbling, with an unsavory smell and odd effect. But the vat is full, and from this admixture are produced potent compounds which no preceding age has known. SECTION IV.--Sir Thomas Browne
