Mrs. Grierson (says she) 'gave a proof of her knowledge in the Latin tongue, by her dedication of the Dublin edition of Tacitus to the lord Carteret, and by that of Terence to his son, to whom she likewise wrote a Greek epigram. She wrote several fine poems in English[1], on which she set so little value, that she neglected to leave copies behind her of but very few. 'What makes her character the more remarkable is, that she rose to this eminence of learning merely by the force of her own genius, and continual application. She was not only happy in a fine imagination, a great memory, an excellent understanding, and an exact judgment, but had all these crowned by virtue and piety: she was too learned to be vain, too wise to be conceited, too knowing and too clear-sighted to irreligious. 'If heaven had spared her life, and blessed her with health, which she wanted for some years before her death, there is good reason to think she would have made as great a figure in the learned world, as any of her sex are recorded to have done. 'As her learning and abilities raised her above her own sex, so they left her no room to envy any; on the contrary, her delight was to see others excel. She was always ready to advise and direct those who applied to her, and was herself willing to be advised. 'So little did she value herself upon her uncommon excellences, that it has often recalled to my mind a fine reflexion of a French author, _That great geniuses should be superior to their own abilities._ 'I perswade myself that this short account of so extraordinary a woman, of whom much more might have been said, will not be disagreeable to my readers; nor can I omit what I think is greatly to the lord Carteret's honour, that when he was lord lieutenant of Ireland, he obtained a patent for Mr. Grierson, her husband, to be the King's Printer, and to distinguish and reward her uncommon merit, had her life inserted in it.' Thus far Mrs. Barber. We shall now subjoin Mrs. Pilkington's account of this wonderful genius.
