Antiquary, the Spainards borrowed their double L. (LL) from the
people of Mexico, who received it from the Welsh; and the Dutch
brought a Bird with a white Head from the Streights of Magellan,
called by the Natives, Penguin, which word in the Old British (and
in Modern British) signifies 'White Head;' and therefore seems
Originally to have come from Wales. This must be allowed an additional
Argument, to omit others that occur in Favour of Madoc's three
American Expeditions."[dd]

of America, p. 193. Edit. 1748.]

It would hence seem that these Writers were inclined to believe
the Tradition concerning Madog; for they say that it is a notion
supported by something more than bare Conjectures.

They say also that they have omitted other Arguments in Favour of
Madog's Expeditions.

In the British Tongue, the double L (LL) hath a peculiar sound,
different from any in other Tongues. It hath been said that in
the Spanish it has the same sound. But a Gentleman who understands
the Spanish Language informed me that it is not like the Welsh
double, LL, though it hath a peculiar sound. However, if the Spanish
Tongue hath such a sound, or one near to it, it might have been
derived from the Inhabitants of Mexico or Guatimala; for we have
very strong reasons to believe that the Descendants of Madog's
Colony, spread themselves over a great part of America. But more
of this hereafter.
