(Edinburgh: Adam and Charles Black, 1889), p. 405 (on Miss Elizabeth Smith):
On my first becoming acquainted with Miss Smith's pretensions, it is very true that I regarded them with but little concern; for nothing ever interests me less than great philological attainments, or at least that mode of philological learning which consists in mastery over languages. But one reason for this indifference is, that the apparent splendour is too often a false one. They who know a vast number of languages rarely know any one with accuracy; and, the more they gain in one way, the more they lose in another. With Miss Smith, however, I gradually came to know that this was not the case; or, at any rate, but partially the case; for, of some languages which she possessed, and those the least accessible, it appeared, finally, that she had even a critical knowledge. It created also a secondary interest in these difficult accomplishments of hers, to find that they were so very extensive. Secondly, That they were pretty nearly all of self-acquisition. Thirdly, That they were borne so meekly, and with unaffected absence of all ostentation. As to the first point, it appears (from Mrs. H. Bowdler's Letter to Dr. Mummsen, the friend of Klopstock) that she made herself mistress of the French, the Italian, the Spanish, the Latin, the German, the Greek, and the Hebrew languages. She had no inconsiderable knowledge of the Syriac, the Arabic, and the Persic.
