Sorry this site doesn't exist any longer.
I did not find time to translate all in english nor did i find someone to help me in that enterprise.
I suggest you go now to the french version of the page located here :
http://www.multimania.com/nea/nea1789-1794/htm/home/lance.htm

Desolé, cette page n'existe plus.
Le site est maintenant concentré à l'adresse suivante :
