58 The Scottish Naturalist. 



to me by my sister, Mrs. Wills, at Shenards, near Welvryn, in 

 that county, last summer." 



In July 187 1, the late Sir Henry Holland* thus addressed me : 

 " I cannot feel satisfied without writing a few lines to thank you for 

 the very valuable Treatise on ' The Physiology and Pathology of 

 Mind in the Lower Animals.' ... I am one of those who do not 

 object to the word ' Mind ' thus applied, as you will see, I think, 

 in an article I wrote for the Edinburgh Review of January last, 

 on the 3 vols, of M. Laugas, having relation to this and other 

 kindred subjects. You will observe in this article (written on a 

 voyage to and from Jamaica last autumn), that I especially 

 allude to the Sense of Fun in the higher animals, as a striking 

 demonstration of the relation of their faculties to those of man. 

 I do not perceive that you include this in your Enumeration, 

 but it undoubtedly ought to have place there." 



It is quite the case that I have not yet published all the ma- 

 terial I have collected in proof of the possession by other 

 animals, as well as man, of a Sense of Fun or Humour. Such 

 proofs, if not very abundant, are at least convincing. They 

 are to be found for instance, in those very "practical jokes" 

 which certain animals play, not only upon each other, but upon 

 man himself. 



In August 1 87 1, I had the following letter from Dr. Humph- 

 reys Storer of Boston, Massachusetts, formerly Professor of 

 Obstetrics and Medical Jurisprudence in Harvard University, 

 Cambridge, Mass. 



" I have been much gratified by reading your paper in the 

 ' British and Foreign Medico-Chirurgical Review,' on ' Insanity 

 in the Lower Animals,' and feel prompted to send you an 

 anecdote relating to a favourite Newfoundland Dog of my own, 

 which, on account of his size, I was compelled to destroy, a 

 few years since, at the age of 13 J years. I relate this to show you 

 that dogs do not always want the faculty of speech, to make 

 themselves fully understood. My dog ' Tiger ' — a splendid fellow 

 weighing over 90 lbs. — was a great favourite with my whole 

 family, and consequently was allowed, for several years, to do 

 pretty much as he pleased. Upon removing my residence to 

 another portion of the city, the new house was fitted up with 

 some more costly furniture, requiring more care in its preserva- 

 tion than we had been accustomed to bestow upon the old.
