_Parallels_.--“Jonah rings” have been put together by Mr. Clouston
in his _Popular Tales_, i. 398, &c.: the most famous are those of
Polycrates, of Solomon, and the Sanskrit drama of “Sakuntala,” the plot
of which turns upon such a ring. “Letters to kill bearer” have been

“the substituted letter” by the same authority in _Occ. u. Or._, ii.
289. Mr. Baring-Gould, who was one of the pioneers of the study of
folk-tales in this country, has given a large number of instances of
“the pre-ordained marriage” in folk-tales in Henderson, _l.c._
