In his travels to Cambridge, which began to be frequent about this time, his gains were greater. For there he first became acquainted with Miss Emma Isola, for whom, as I can testify, he at all times exhibited the greatest parental regard. When he and Mary Lamb first knew her, she was a little orphan girl, at school. They invited her to spend her holidays with them; and she went accordingly: the liking became mutual, and gradually deepened into great affection. The visit once made and so much relished, became habitual; and Miss Isola's holidays were afterwards regularly spent at the Lambs' house. She used to take long walks with Charles, when his sister was too old and infirm to accompany him. Ultimately she was looked upon in the light of a child; and Charles Lamb, when speaking of her (and he did this always tenderly), used invariably to call her "Our Emma." To show how deep his regard was, he at one time was invited to engage in some profitable engagement (1830) whilst Miss Isola was in bad health; but he at once replied, "Whilst she is in danger, and till she is out of it, I feel that I have no spirits for an engagement of any kind." Some years afterwards, when she became well, and was about to be married, Lamb writes, "I am about to lose my only walk companion," whose mirthful spirits (as he prettily terms it) were "the youth of our house." "With my perfect approval, and more than concurrence," as he states, she was to be married to Mr. Moxon. Miss Emma Isola, who was, in Charles Lamb's phrase, "a very dear friend of ours," remained his friend till death, and became eventually his principal legatee. After her marriage, Charles, writing to her husband (November, 1833), says, "Tell Emma I every day love her more, and miss her less. Tell her so, from her loving Uncle, as she has let me call myself." It was, as I believe, a very deep paternal affection. The particulars disclosed by the letters of 1823 and 1824 are so generally unimportant, that it is unnecessary to refer to them. Lamb, indeed, became acquainted with the author of "Virginius" (Sheridan Knowles), with Mr. Macready, and with the writers in the "London Magazine" (which then had not been long established). And he appears gradually to discover that his work at the India House is wearisome, and complains of it in bitter terms: "Thirty years have I served the Philistines" (he writes to Wordsworth), "and my neck is not subdued to the yoke." He confesses that he had once hoped to have a pension on "this side of absolute incapacity and infirmity," and to have walked out in the "fine Isaac Walton mornings, careless as a beggar, and walking, walking, and dying walking;" but he says, "the hope is gone. I sit like Philomel all day (but not singing), with my breast against this thorn of a desk."
