References appear with "et" instead of "and" between authors

[ChiPro]

Hi all,

I'm using BibDesk as my reference package in Lyx. I have set the Lyx options
(Documents > Settings) to "Natbib: Author-year" and the citation style to
"[author1] and [author2] ([year])".

Unfortunately, when I produce my PDF file, the reference appears as


[Author1] et [Author2] (2000)


instead of the desired


[Author1] and [Author2] (2000).


Any help would be appreciated.

Thanks,
CP
