This space involves: a 'vertical', in which the implications are drawn up fever, 'a successive struggle between cold and heat', may occur in a single episode, or in several; these may follow without interruption or after an interval; this respite may not exceed twelve hours, attain a whole day, last two whole days, or have a poorly defined rhythm;' and a 'horizontal', in which the homologies are transferred in the two great subdivisions of the spasms are to be found, in perfect symmetry, the `partial tonics', the 'general tonics', the 'partial clonics', and the 'general clones';' or again, in the order of the discharges, what catarrh is to the throat, dysentery is to the intestines; a deep space, anterior to all perceptions, and governing them from afar; it is on the basis of this space, the lines that it intersects, the masses that it distributes or hierarchizes, that disease, emerging beneath our gaze, becomes embodied in a living organism.
