Perhaps you should try some spelling variations:
"acta philosophical mechanical" » "acta philosophical mechanics", "acta philosophical ethical", "acta philosophical medical", "meta philosophical mechanical", "art philosophical mechanical", "a philosophical mechanical"
"acta philosophia mechanica" » "acta philosophical mechanics", "acta philosophie mechanique", "acta philosophia britannica", "act philosophy mechanica", "a philosophia mechanica", "la philosophia mechanica"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"acta philosophia mechanica\") OR (\"acta philosophical mechanical\"))".
• Removing quotes may allow a broader search: (( acta philosophia mechanica ) OR ( acta philosophical mechanical )).
• Adding a wildcard symbol may retrieve word variants: (("acta philosophia mechanica") OR ("acta philosophical mechanical"))*.
