     What a stir about nothing! Phenicopter is no more (pace Dr Septimus Wind and his eyriecal friend, Dr Eagles) than the common flamingo (simplex). Why ask such silly questions? What, for example, is a caterpillar? and why so denominated? There is the common quail as there is the common flag-beetle. A king (or queen) fisher might devour eaglets, but what is that to the spider in ordinary? and what has the spider to do with the Neapolitan tarentella? Unicorns and bicorns may be gregarious without even subterfuge or sideral ornament.

     But as far as horned species are concerned, if these natural defences were the result of buntings, we should have races of unicorns, not bicorns, that is, the horns ought to have shot out on the spots of the natural “stimulus” from the foreheads, not from the sides!

     Buttings and batterings mean that the points of impact would be the frontal portion of the skull, so that if such batterings and buttings had anything to do with the inducing the flow of blood thereto and the consequent inducement of growth, the result would have been unicorns, not bicorns in which the horns appeared at points not affected by the impacts.

They illustrate a venerable controversy: are we looking at unicorns, or bicorns in profile?

     Sympathetic to the animal’s plight, the dwarf mongoose was about to propose support for rhinoceros protection and conservation, when Tosthenes took everyone off balance with his delighted mooing. / ‘That’s only one of my skills. I like composing acrostics while calculating the number of oxpeckers cleaning ticks from buffalo, giraffes and fellow rhinos. Let me give you an example: / Benign shrub and tree browsing / Individuals, members of the / Contemplative class / Of higher mammals / Rational in our mud-bathing, though / Near-sighted, our existence is threatened by / Savage horn coveters. / ‘Bicorns,’ said Snowcub who, later on, would be horrified at the memory of how he had at this point taken fancy to and snapped up a fat spider appearing from out of nowhere under his nose. / Tosthenes snorted approval. ‘A sharp-minded mongoose with anything but a dwarf brain. Yes, we prefer to think of ourselves as bicorns. The perpendics rarely make sense. Why, if they named another creature unicorn, did they slap that Greek tag on us?’
