88 THE POPULAR SCIENCE MONTHLY. 



and of their total want of conscience." I think this observation is 

 warranted by the facts, for although I have heard it objected that the 

 feeling displayed by the terrier in this case was that of wounded pride 

 rather than of wounded conscience, still, from what has been previ- 

 ously said concerning this distinction in the case of animals, it will be 

 seen that in this instance it is not easy to draw the line between these 

 two sentiments. 



The followin"- instances, however, all of which occurred with the 

 terrier just mentioned, are free from this difficulty : 



For a long time this terrier was the only canine pet I had. One 

 day, however, I brought home a large dog, and chained him up out- 

 side. The jealousy of the terrier toward the new-comer was extreme. 

 Indeed, I never before knew that jealousy in an animal could arrive at 

 such a pitch ; but, as it would occupy too much space to enter into 

 details, it will be enough to say that I really think nothing that could 

 have befallen this terrier would have pleased him so much as would 

 any happy accident by which he might get well rid of his rival. Well, 

 a few nights after the new dog had arrived, the terrier w r as, as usual, 

 sleeping in my bedroom. About one o'clock in the morning he began 

 to bark and scream very loudly, and, upon my waking up and telling 

 him to be quiet, he ran between the bed and the window in a most 

 excited manner, jumping on and off the toilet-table after each jour- 

 ney, as much as to say: "Get up quickly; you have no idea of what 

 shocking things are going on outside ! " Accordingly, I got up, and 

 was surprised to see the large dog careering down the road ; he had 

 broken loose, and, being wild with fear at finding himself alone in a 

 strange place, was running he knew not whither. Of course I went 

 out as soon as possible, and after about half an hour's work succeeded 

 in capturing the runaway. I then brought him into the house and 

 chained him up in the hall ; after which I fed and caressed him with 

 the view of restoring his peace of mind. During all this time the 

 terrier had remained in my bedroom, and, although he heard the 

 feeding and caressing process going on down-stairs, this was the only 

 time I ever knew him fail to attack the large dog when it was taken 

 into the house. Upon my reentering the bedroom, and before I said 

 anything, the terrier met me with certain indescribable grinnings and 

 prancings, which he always used to perform when conscious of hav- 

 ing been a particularly good dog. Now, I consider the whole of this 

 episode a very remarkable instance in an animal of action prompted 

 by a sense of duty. No other motive than the voice of conscience can 

 here be assigned for what the terrier did ; even his strong jealousy ot 

 the large dog gave way before the yet stronger dread he had of the 

 remorse he knew lie should have to suffer, if next day he saw me dis- 

 tressed at a loss which it had been in his power to prevent. What 

 makes the ease more striking is, that this was the only occasion dur- 

 ing the many years he slept in my bedroom that the terrier disturbed
