Hereof there want not many examples in _Aristotle_, through all his Book of Animals; we shall instance onely in three of his Problems, and all contained under one Section. The first enquireth, why a Man doth cough, but not an Oxe or Cow; whereas, notwithstanding the contrary is often observed by Husbandmen, and stands confirmed by those who have expressly treated _De Re Rustica_, and have also delivered divers remedies for it. Why Juments, as Horses, Oxen, and Asses, have no eructation or belching, whereas indeed the contrary is often observed, and also delivered by _Columella_. And thirdly, Why Man alone hath gray hairs? whereas it cannot escape the eyes, and ordinary observation of all men, as Horses, Dogs, and Foxes, wax gray with age in our Countries; and in the colder Regions, many other Animals without it. And though favourable constructions may somewhat extenuate the rigour of these concessions, yet will scarce any palliate that in the fourth of his Meteors, that Salt is easiest dissolvable in cold water: Nor that of _Diascorides_, that Quicksilver is best preserved in Vessels of Tin and Lead. Other Authors write often dubiously even in matters wherein is expected a strict and definite truth; extenuating their affirmations, with _aiunt_, _ferunt_, _fortasse_: as _Diascorides_, _Galen_, _Aristotle_, and many more. Others by hear-say; taking upon trust most they have delivered, whose Volumes are nicer Collections, drawn from the mouths or leaves of other Authors; as may be observed in _Plinie_, _Elian_, _Athenæus_, and many more. Not a few transcriptively, subscribing their Names unto other mens endeavours, and meerly transcribing almost all they have written. The _Latines_ transcribing the _Greeks_, the _Greeks_ and _Latines_, each other. [Sidenote: _The Antiquity, and some notable instances of Plagiarism, that is, of transcribing or filching Authors._]
