Adjectives, and their Substantives, denoting Number and Multitude, are used in the singular Number: As, _Populus frequens_; _multa rosa_; _innumera avis_; _quam multo repetet Græcia milite_; _licet illi plurima manet lacrima_.
To mention but one Observation more: Some Adjectives, which in common Prose agree with their Substantives, are turned into the Neuter Gender and plural Number, and the Substantives into the Genitive Case: As, _Ultima mundi_; _ardua montis_; _cuncta terrarum_; _prospera rerum_; _dura rerum_; _aspera ponti_; _acuta belli_; _strata viarum_; _opaca locorum_; and many more to the like Purpose.
It would be endless, to produce all the Examples that come under these Rules; they abound in every Page almost of the best Poets, especially the _Lyric:_ For the _Lyrics_ chiefly delight in the true poetic Style, as may be collected from the Examples I have here produced, most of them from the Odes of _Horace_. But there are, besides, various poetical Expressions, which tho' not reducible to any particular Class, yet occur up and down in Reading, and are worthy of treasuring up in the Memory. Such are frequent in _Virgil_:
----_dederatque comam diffundere ventis_[22].
And giv'n the Winds, To wanton in her Tresses.
_Ut cum carceribus sese effudêre quadrigæ, Addunt se in spatia, & frustra retinacula tendens Fertur equis auriga, neque audit currus habenas_[23].
As when the Racers from the Barriers start, Oft whirling round the Goal, the Charioteer Vainly attempts to check the flying Steeds. Himself is born away, the dusty Car Swift smoaks along, nor bounding hears the Reins.
_Sic laudamus equum, facilis cui plurima palma Fervet, & exultat rauco victoria Circo: Nobilis hic, quocunque venit de gramine, cujus Clara fuga ante alios, & primus in æquore pulvis_[24].
We commend a Horse (Without Regard of Pasture, or of Breed) For his undaunted Mettle, and his Speed;
Who wins most Plates, with greatest Ease, and first Prints with his Hoofs his Conquest on the Dust. _G. Stephens._
But especially in the Prince of the Lyric Poets:
In rusty Silence mourns your Gate. _Oldsworth._
----_& ademptus Hector Tradidit fessis leviora tolli Pergama Graiis._
_Qua pinus ingens, albaque populus, Umbram hospitalem consociare amant Ramis, & obliquo laborat Lympha fugax trepidare rivo._
