Irrestrainable

Direr still, hideous clamor of masked cannon, right in their very faces, added the horror of surprise to the disorder of attack, and the thick blue lines broke in irrestrainable confusion.

Madame d'Houdetot for the next three or four months, which were among the most bitter in Rousseau's life, for then the bitterness which became chronic was new and therefore harder to be borne, wrote him the wisest, most affectionate, and most considerate letters that a sincere and sensible woman ever wrote to the most petulant, suspicious, perverse, and irrestrainable of men.

We appreciate that this may not be the expression of an irrestrainable vanity, or obsessing greed, realising that very probably his professional insight into human character informs him that the subject of the sales of books is the range of the book clerk's mind.
