Perhaps you should try some spelling variations:
specimina philologica » specimens philological
specimina philologiae » specimens philological, specimen philosophiae
philologiae slavicae » philologica slavicae, philologica slavica, philologie slave
specimen philologiae » specimens philological, specimen philosophiae, specimen histological

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((specimina philologica) OR (specimina philologiae)) slavicae ) OR ( specimen philologiae slavicae ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((specimina philologica) OR (specimina philologiae)) slavicae ) or ( specimen philologiae slavicae ))*".
