During this summer of 1846, while her literary hopes were waning, an anxiety of another kind was increasing. Her father's eyesight had become seriously impaired by the progress of the cataract which was forming. He was nearly blind. He could grope his way about, and recognise the figures of those he knew well, when they were placed against a strong light; but he could no longer see to read; and thus his eager appetite for knowledge and information of all kinds was severely balked. He continued to preach. I have heard that he was led up into the pulpit, and that his sermons were never so effective as when he stood there, a grey sightless old man, his blind eyes looking out straight before him, while the words that came from his lips had all the vigour and force of his best days. Another fact has been mentioned to me, curious as showing the accurateness of his sensation of time. His sermons had always lasted exactly half an hour. With the clock right before him, and with his ready flow of words, this had been no difficult matter as long as he could see. But it was the same when he was blind; as the minute-hand came to the point, marking the expiration of the thirty minutes, he concluded his sermon.
