..the category of stones. Wilkins divides them into common (silica, gravel, schist), modics (marble, amber, coral), precious (pearl, opal), transparent (amethyst, sapphire) and insolubles (chalk, arsenic). Almost as surprising as the eighth, is the ninth category. This one reveals to us that metals can be imperfect (cinnabar, mercury), artificial (bronze, brass), recremental (filings, rust) and natural (gold, tin, copper). Beauty belongs to the sixteenth category; it is a living brood fish, an oblong one.

These ambiguities, redundancies and deficiencies remind us of those which doctor Franz Kuhn attributes to a certain Chinese encyclopaedia entitled 'Celestial Empire of benevolent Knowledge'. In its remote pages it is written that the animals are divided into: (a) belonging to the emperor, (b) embalmed, (c) tame, (d) sucking pigs, (e) sirens, (f) fabulous, (g) stray dogs, (h) included in the present classification, (i) frenzied, (j) innumerable, (k) drawn with a very fine camelhair brush, (l) et cetera, (m) having just broken the water pitcher, (n) that from a long way off look like flies.
