Dear Vern, I found the death record of a William STIMPSON, aged 42, sailer, born in Leftshire? England, who died in the Hopital de la conception, Marseille 27 Aug 1875.
Click on "Marseille", "Registres ..." and "Rechercher".
Next page, click on "Sépulture, décès", then against where it says "Annee" put 1875 in the second box, then click on "Selectionner un mois" and chose "aout", then click on "Rechercher" at the bottom.
Next page: tick the box against the second entry: "
MARSEILLE , Acte : Décès , 1875 , Août , Registre : 6 "
and then click on the binoculars symbol.
That should get you to the register, you want page 52 of 64. bottom left.
the record also states "no other information", presumably they mean they cannot give his parents' names.
I hope this helps,
