Sir Humphry's health was in so shattered a state, that it often rendered his inclinations and feelings sensitive and variable to a painful degree. Frequently he preferred being left alone at his meals; and in his rides, or fishing and shooting excursions, to be attended only by his servant. Sometimes he would pass hours together, when travelling, without exchanging a word, and often appeared exhausted by his mental exertions. When he passed through Heidelberg to see my mother, he named all this to her, and with evident feeling thanked her for her request, that he would on all occasions consider me as alone desirous to contribute to his ease and comfort. I mention this to account for my having so seldom spoken of his passing remarks, and for any apparent change which occurred in our arrangements, named in the Journal. To give any adequate idea of the beauty and grandeur of the scenes I beheld, must be well known to be impossible by those who have visited these parts of Europe, or been accustomed to view the changing tints and hues of the fine sky that encircles them; but if I have imparted only a faint reflection of the pleasure such scenes bestow, even in recollection, or have given enjoyment to any of my readers, my object will be fully attained, nor shall I then regret having listened to the voice of my perhaps too partial friends.
