_Spelling of Britannia, &c._ (Vol. iii., pp. 275. 463.).--I believe that
there is no mistake as supposed in the inscription on the Geo. III.
shilling. The double "T" is expressive of the plural "Britt." for
"Britanniarum". Have we not many similar instances, _e. g._ "codd." for
"codices," "libb." for "libri;" or, one of every-day occurrence, "pp."
for "pages?"
