Falcons (from falx, a reaping-hook) are marvellously organised for rapine, and realise the ideal of a bird of prey.
The Faus (falso: from falx) appears to have been a kind of spear with a broad, cut-and-thrust blade.
From this septum is formed the falx cerebri and other parts.
It is divided into two hemispheres by the falx cerebri, a partition which follows the middle line of the skull.
Into this cleft dips a portion of the dura mater, called the falx cer´e-bri, from its resembling a sickle.
In the falx is a poison-sac from which poison flows through the hollow fang and out at its tip.
