Perhaps you should try some spelling variations:
"specimen histological polemical" » "specimen philological polemical", "specimen histological cortical", "specimen historical political", "specimens philological polemical", "specimen pathological polemical", "special histologic polemical"
"species pathologic slavicae" » "species philologica slavicae", "species philologiae slavicae", "specific pathologic slavicae", "species pathogenic slavicae", "specimen pathological slavicae"

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: "((\"species pathologic slavicae\") OR (\"specimen histological polemical\"))".
• Removing quotes may allow a broader search: (( species pathologic slavicae ) OR ( specimen histological polemical )).
• Adding a wildcard symbol may retrieve word variants: (("species pathologic slavicae") OR ("specimen histological polemical"))*.
