"Though I deeply felt the pain of leaving my adoptive home, yet I fancied it would not become me as a man to show any emotion, still my voice failed me when my dear mother embraced me with tears in her eyes. Little Ellen stood pale, and silent by her side. I turned to her with some joke and jestingly gave her different directions about the care of my zoological collection, (preserved in camphor and spirits of wine) which I had entrusted to her charge. Then I drew this child of eight into my arms to bid her farewell. As I kissed her, I was startled by a sudden shudder which ran through her frame, as if an asp had bitten her. She staggered back with closed eyes and nearly fainted away. She quickly recovered however, and next day wrote me a childishly merry letter. "Since that day I only once touched her lips again, and then they were cold and closed for ever. "How the six years of my University career passed, how I found life at home when I returned for the holidays would be useless to relate. It would be a long, and monotonous narrative. Some estrangement arose between me and my foster-sister, partly through my fault, for science and study monopolized my attention more and more. From year to year this strange girl grew more reserved in my presence. Only in her charming letters could I discover a trace of the old intimacy of our childhood. "Her outward development did not fall short of its early promise. "She was fullgrown at the age of fourteen; somewhat slender, but quite formed. The small portrait of her which I once showed you has but little resemblance. Her character, if I may so express my self, was even more mature than her person, and only betrayed itself in her movements. A stately calm, an indifference, scarcely concealed for many things which generally appear alluring at her age, isolated her a good deal. Then again, when she wished to please, her smile, the gentle and timid yielding up of herself had a charm not to be described. Few knew her real value, her genuine upright soul; and among those few, her brother was not. I was then too much engrossed by my studies, too eager to solve the mysteries of physical science, to care about the secrets of that young heart. Strange to say although I was always of a sensual disposition, and certainly no paragon of virtue, and having eyes to see could easily perceive, that all my conquests, compared with that remarkable girl, appeared like housemaids beside a young princess, yet it never entered my head to fall in love with her. When I wrote home, it was always to my foster-mother, and she had to remind me sometimes, of what was due to my little sister. "She once wrote that the child who was as reserved as ever, did not show what she felt, although my neglect seemed to hurt her, and one day when I had forgotten even to mention her in my letter, she had cried the whole night.
