Of these Counts the learned Selden reckons but 6 Sorts, viz. the Single Count, (who hath no addition but his Christian name) 2d. Count Palatine (from Palatium or some Palace in it,) 3d. Count of the Empire, 4th. Count of Frontiers, where the Title of Mar∣quess is also us'd instead of Count, 5th. Count of Provinces, (or Counties joyn'd) which in Foraign parts are call'd Landgraves, (the word Grave and Comes signifying the same Title) and 6th. Count of Cities or Towns, and these latter, as in England, are call'd Comites Castrenses or Burgraves, or Counts of Castles or Burroughs, (all which are more fully describ'd in his second Book.) But I find that Cassiodorus in his 6th. Book mentions 22 Sorts more than Mr. Selden, of which 6 of Mr. Seldens, or 28 of Cassiodorus, we in England re∣tain but few, viz. a Count of a County, (as Algernonus, Comes Northumbriae; A Count of a City, (as Albericus or Awbry, Comes Oxoniae (or Oxford,) and Guilel∣mus, Comes Novi Castri or New Castle upon Tine, (being both a Castle and Burrough.)
3. All the curiosity lies in finding out how Comes or Count happens to be trans∣mutted into the word Earl, so much dif∣ferent in Pronuntiation and Orthography from each other, and yet, as we say, are the same in Substance.
