Die Physiologie und Psychologie des Lachens und des Komischen
by Ewald Hecker
If I lay the present little book on the Christmas table for you, dear Kahlbaum, I know, of course, that I will not make you unexpected surprise with it; for you knew about the creation of the little work, and from the beginning you took the most lively interest in it. But I hope to give you a little pleasure anyway. Above all, however, I would like to relieve you, with the dedication of this book, of a small portion of the gratitude which I owe you in so great a measure for the cordial interest that you have always taken in me and my spiritual education, for the friendly sympathy that you mean Free studies, for your constant readiness to respond to my plans and work and to support me with true advice
