L
Labored and far-fetched elocution
Laid down in a most unflinching and vigorous fashion
Lamentable instances of extravagance
Lash themselves into fury
Lax theories and corresponding practises
Lay hold of the affections
Leaden mood of dulness
Lend a critical ear
Lest the requirements of courtesy be disregarded
Links in the chain of reasoning
Little less than scandalous
Lofty and distinguished simplicity
Long-sighted continuity of thought and plan
Looking at the matter by and large
Looming large and ugly in the public view
Loose and otiose statement [otiose = lazy; indolent; of no use]
Lost in indolent content
Lovely beyond all words
Lucidity and argumentative vigor
Lulled into a sense of false satisfaction
