and avoids them. At night he sleeps, curled up as is the 

 mode with normal dogs. To awake him a loud sound, e.g., 

 the bray of a bicycle horn, is requisite. It is easier to 

 awake him by a pat on the flank, and to this, if repeated, he 

 soon answers with a growl. When awake, if one of his 

 feet be taken he tries to escape much as a normal dog 

 will try, but somewhat awkwardly ; if not released he barks 

 angrily and turning his head bites at the hand holding him, 

 though clumsily missing his object sometimes widely and 

 biting the air. If, as he is standing quietly, one foot be 

 moved into a strained position, it is at once withdrawn and 

 the uneasy pose corrected. When placed on a table, in the 

 top of which there is a little trap-door so that one of his feet 

 set on the trap can be let slowly down from under him, he 

 allows the foot to sink a little way and then withdraws it 

 smartly. One of the dogs in running about injured a hind- 

 foot ; after the hurt it still continued to roam on, but limping 

 with three legs ; that is, it was able to co-ordinate movements 

 quite unusual to it. With these dogs when a light draught 

 of air through a tube was turned upon the conjunctiva, the 

 eye blinked and the head was turned aside. When the 

 draught was directed to the ear the head was shaken. 

 On the other hand, when the draught was turned upon 

 the hair of the feet no notice was taken, although a 

 normal dog will lift the foot at once and search for the 

 disturbance. 



The dog can feed itself, eating solid food, crunching 

 bones and lapping up milk or water ; but to start its 

 feeding the muzzle has to be dipped into the dish. Food is 

 not sought for, yet if feeding time be deferred the dog 

 begins to show signs which seem to indicate impatience ; 

 he begins to move quickly about his cage, and rears himself 

 against the bars, putting up his fore-paws on the railing. A 

 little quinine (bitter) added to his sop of meat and milk led to 

 the morsels, after being taken into the mouth, being without 

 hesitation rejected. None were ever swallowed, although 

 directly an undoctored piece was given it was swallowed and 

 apparently with relish. Goltz threw to his own house-dog 

 a piece of the same doctored meat. The creature wagged
