particular marks of confidence and favour

This caution produced overtures from a great many young gentlemen of rank and distinction, who courted my alliance, by demanding Serafina in marriage; and from the number I had actually selected one person, who was in all respects worthy the possession of such an inestimable prize. His name was Don Manuel de Mendoza. His birth was noble, and his character dignified with repeated acts of generosity and virtue. Yet, before I would signify to him my approbation of his suit, I resolved to inform myself whether or not the heart of Serafina was totally unengaged, and indifferent to any other object, that I might not lay a tyrannical restraint upon her inclinations. The result of my inquiry was a full conviction of her having hitherto been deaf to the voice of love; and this piece of information, together with my own sentiments in his favour, I communicated to Don Manuel, who heard these tidings with transports of gratitude and joy. He was immediately favoured with opportunities of acquiring the affection of my daughter, and his endeavours were at first received with such respectful civility, as might have been easily warmed into a mutual passion, had not the evil genius of our family interposed.
O my friend! how shall I describe the depravity of that unhappy virgin’s sentiments! how recount the particulars of my own dishonour! I that am descended from a long line of illustrious Castilians, who never received an injury they did not revenge, but washed away every blemish in their fame with the blood of those who attempted to stain it! In that circumstance I have imitated the example of my glorious progenitors, and that consideration alone hath supported me against all the assaults of despair.
As I grudged no pains and expense in perfecting the education of Serafina, my doors were open to every person who made an extraordinary figure in the profession of those amusing sciences in which she delighted. The house of Don Diego de Zelos was a little academy for painting, poetry, and music; and Heaven decreed that it should fall a sacrifice to its regard for these fatal and delusive arts. Among other preceptors, it was her fate to be under the instruction of a cursed German, who, though his profession was drawing, understood the elements and theory of music, possessed a large fund of learning and taste, and was a person remarkable for his agreeable conversation. This traitor, who like you had lost one eye, I not only admitted into my house for the improvement of my daughter, but even distinguished with particular marks of confidence and favour, little thinking he had either inclination or capacity to debauch the sentiments of my child. I was rejoiced beyond measure to see with what alacrity she received his lessons, with what avidity she listened to his discourse, which was always equally moral, instructing, and entertaining.
