[8] The "Elke" is an obsolete name for the Wild Swan (_Cygnus musicus_), which occurs in the present day in the same numbers and under precisely similar circumstances as Browne describes; but of course this was the only species of wild swan known to him. The remarkable recurvation of the trachea within the keel of the sternum, which also prevails to a greater or less degree in four out of the five or six species of Cygnus found in the Northern Hemisphere, did not escape Browne's notice, although he was not the first to describe it, and he rightly observes that this peculiarity is absent in the Mute Swan (_C. olor_), but exists in a different and even more exaggerated form in the Crane. He, however, was mistaken as to the extreme northerly range which he assigns to this species. So marked a feature as the absence of the "berry" on the beak of this species did not escape Browne's observation, and he refers to it in the eighth letter to Merrett, who in his second letter to Browne remarks "the difference in the elk's bill by you signified is remarkable to distinguish it from others of its kind," indicating that this distinction was previously unknown to him. A white large & strong billd fowle called a Ganet[9] which seemes to bee the greater sort of Larus. whereof I met with one kild by a greyhound neere swaffam another in marshland while it fought & would not bee forced to take wing another intangled in an herring net wch taken aliue was fed with herrings for a while it may be named Larus maior Leucophæopterus as being white & the top of the wings browne. [9] As a rule the Gannet does not approach the shore, except to breed, but follows the shoals of fish far out at sea. The circumstance mentioned by Browne is by no means singular, and several such instances of storm-driven Gannets being captured far inland are recorded. The "Scotch Goose, _Anser scoticus_," mentioned further on (p. 13 _infra_), is also in all probability intended for the Gannet; it is the _Anser Bassanus sive Scoticus_ of Jonston. The "Marshland" here mentioned is a tract of country reclaimed in ancient times from the sea, lying to the west of the town of Lynn, of some 57,000 acres in extent, and bordering upon the estuary of the Wash. [_Fol. 7._] In hard winters I have also met with that large & strong billd fowle wch clusius describeth by the name of Skua Hoyeri[10] [fr _struck out_] sent him from the faro Island by Hoierus a physitian. one whereof was shot at Hickling while 2 thereof were feeding upon a dead horse.
