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

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: (( specimens philological slavicae ) OR ( specimen philosophiae slavicae ))*.
