![[ !<> ] AN ACCOUNT OF AN EXTRAORDINARY PHEASANT. EVERY deviation from that original form and ilru6lure which gives the diftingui£hing charadler to the produdtions of Nature, may not improperly be called monftrous. According to this acceptation of the term, the variety of monfters will be almoft infinite; and, as far as my knowledge has extended, there is not a fpecies of animals, nay, there is not a fingle part of an animal body, which is not fubjed: to an extra- ordinary formation. Neither does this appear to be a matter of mere chance; for it may be obferved, that every fpecies has a difpofition to deviate from Nature in a manner peculiar to itfelf. It is likewife worthy of remark, that each fpecies of animals is difpofed to have nearly the fame fort of defe<fls, and to have certain fupernumerary parts of the fame kind: yet every part is not alike difpofed to take on a great variety of forms; but each part of each fpecies feems to have its monftrous form originally imprefled upon it. It is well known, that many orders of animals have the two parts de- figned for the purpofe of generation different in individuals of the fame fpecies, by which they are diftinguifl:ied into male and female -, but this is not the only mark of diftinftion ; in the greateft part, the male being diftinguifhed from the female by various other marks. The varieties which are found in the parts of generation themfelves, I fhall call the iirft, or principal marks, being originally formed in them and belonging equally to both fexes; all others depending upon thefe I fhall call fecon- dary, as not taking place till the firft are becoming of ufe, and being principally, although not entirely, in the male. One of the moft general marks is, the fuperior ftrength of make in the male ; and another circumftance, perhaps equally fo, is this ftrength being dired;ed to one part more than another, which part is that moft](https://iiif.wellcomecollection.org/image/b21172924_0111.jp2/full/800%2C/0/default.jpg)
