The verb and adverb are precisely in the same condition with the substantive and adjective. An adverb, which expresses a certain modification of the action expressed by the verb, is not separable from it even in imagination. And therefore I must also give up the following lines.

And which it much || becomes you to forget
’Tis one thing madly || to disperse my store

But an action may be conceived leaving out a particular modification, precisely as a subject may be conceived leaving out a particular quality; and therefore when by inversion the verb is first introduced, it has no bad effect to interject a pause betwixt it and the adverb which follows. This may be done at the close of a line, where the pause is at least as full as that is which divides the line:

While yet he spoke, the Prince advancing drew
Nigh to the lodge, &c.

The agent and its action come next, expressed in grammar by the active substantive and its verb. Betwixt these, placed in their natural order, there is no difficulty of interjecting a pause. An active being is not always in motion, and therefore it is easily separable in idea from its action. When in a sentence the substantive takes the lead, we know not that action is to follow; and as rest must precede the commencement of motion, this interval is a proper opportunity for a pause.

On the other hand, when by inversion the verb is placed first, is it lawful to separate it by a pause from the active substantive? I answer not, because an action is not in idea separable from the agent, more than a quality from the substance to which it belongs. Two lines of the first rate for beauty have always appeared to me exceptionable, upon account of the pause thus interjected betwixt the verb and the consequent substantive; and I have now discovered a reason to support my taste:

In these deep solitudes and awful cells,
Where heav’nly-pensive || Contemplation dwells,
And ever-musing || Melancholy reigns.

The point of the greatest delicacy regards the active verb and the passive substantive placed in their natural order. On the one side it will be observed, that these words signify things which are not separable in idea. Killing cannot be conceived without some being that is put to death, nor painting without a surface upon which the colours are spread. On the other side, an action and the thing on which it is exerted, are not, like substance and quality, united in one individual subject. The active subject is perfectly distinct from that which is passive; and they are connected by one circumstance only, that the action exerted by the former, is exerted upon the latter. This makes it possible to take the action to pieces, and to consider it first with relation to the agent, and next with relation to the patient. But after all, so intimately connected are the parts of the thought, that it requires an effort to make a separation even for a moment. The subtilising to such a degree is not agreeable, especially in works of imagination. The best poets however, taking advantage of this subtilty, scruple not to separate by a pause an active verb from its passive subject. Such pauses in a long work may be indulged; but taken singly, they certainly are not agreeable. I appeal to the following examples.

The peer now spreads || the glitt’ring forfex wide

As ever sully’d || the fair face of light
