Miss Graham continued to reside in London, and to devote herself more unreservedly to various studies and active labours in the service of God her Saviour. During her residence in the metropolis, the ministry of the Rev. Watts Wilkinson, and a deep study of the sacred volume, were the means of advancing her knowledge and experience of scriptural truth. Adorned by God with high intellect, which she cultivated with care, and sanctified for her Master’s service, she thirsted for knowledge, and relished its acquisition with peculiar delight. She wrote a treatise on the intellectual, moral, and religious uses of mathematical science, which abounds with wise and judicious observations on the objects and motives of the worldly and Christian student.
But her studies were not confined to the severer branches of knowledge. In some of her more lively exercises of mind she took up the subject of chemistry. She wrote a short but accurate development of the principles of music. Botany also attracted her attention. She had prosecuted, as one of her chiefest studies, the noble literature and tongue of Britain. The best writers on the philosophy of mind were familiar to her. With the principles of Locke she was thoroughly acquainted. She had profited much by Stewart. “Butler’s Analogy” was also upon her first shelf. She had cultivated an acquaintance with the classics of ancient Greece and Rome, and was perfectly familiar with the French, Italian, and Spanish languages. In order to improve herself in the knowledge of the languages, she made considerable use of them in mutual correspondence with her young friends.
Her peculiar singleness of aim stimulated her to apply her literary acquisitions to valuable practical purposes. The discovery of a strong tincture of infidelity among the Spanish refugees, combined with the recollection of her own fall, excited a compassionate, earnest, and sympathetic concern on their behalf. The following extract from a letter written in September, 1825, gives a touching view of her feelings towards these unhappy men. “I have read one part of ‘Las Ruinas,’ and in reading it I was struck with the reflection that the best answer would be a continual reference to the word of God. I thought therefore of placing my observations on the blank pages, and of filling the margin of the printed paper with references. I beseech you to pray, that if I be not a fit instrument for the conversion of the souls of these poor Spanish exiles, the Holy Spirit would be pleased to raise up some other.”
