NATURALL augurie is a physicall or philosophicall observation; bicause humane and naturall reason may be yeelded for such events: as if one heare the cocke crow manie times together, a man may ghesse that raine will followe shortlie; as by the crieng of rooks, and by their extraordinarie using of their wings in their flight, bicause through a naturall instinct, provoked by the impression of the heavenlie bodies, they are mooved to know the p. 209 times, according to the disposition of the weather, as it is necessarie for their natures. And therefore Jeremie saith; Milvus in cœlo cognovit tempus suum. The physician may argue a strength towards in his patient, when he heareth him neeze twise, which is a naturall cause to judge by, and conjecture upon. But sure it is meere casuall, and also verie foolish and incredible, that by two neezings, a man should be sure of good lucke or successe in his businesse; or by meeting of a tode, a man should escape a danger, or atchieve an enterprise, &c.
