"Mingled considerations" may produce a "ferment in the oeconomy" of the mind
Metaphor in Context
In the mean time Sir Launcelot, having ordered supper, retired into his own chamber, and gave a loose to the most tender emotions of his heart. He recollected all the fond ideas which had been excited in the course of his correspondence with the charming Aurelia. He remembered, with horror, the cruel letter he had received from that young lady, containing a formal renunciation of his attachment, so unsuitable to the whole tenour of her character and conduct. He revolved the late adventure of the coach, and the declaration of Mr. Clarke, with equal eagerness and astonishment; and was seized with the most ardent desire of unravelling a mystery so interesting to the predominant passion of his heart. --All these mingled considerations produced a kind of ferment in the oeconomy of his mind, which subsided into a profound reverie, compounded of hope and perplexity.
