THE PSYCHIC DEVELOPMENT OF YOUNG ANIMALS 141 
The bitch puppy was taken upstairs in my house to- 
day to be weighed. She, like two of the dogs, seemed 
abashed by the new surroundings, but soon recovered, 
and when some one entered by the front door down- 
stairs, one storey, turned the head in the direction of 
the sound. 
50th day— When crying this morning, one of them 
was well whipped, with the result that it remained 
quiet for some hours after. Dogs, young and old, easily

it meant (had been before whipped two or three times), 
As I moved the whip she put up one paw as if to ward 
it off. 
52nd day.—Cooler to-day and the puppies are quieter.

like an old dog than formerly. 
53rd day—When I lift the whip, and wave it 3 
feet above them, another lifts a paw. They all look as 
if they knew the meaning of a whip better. 
When I shouted “ Puppy!” from an upper verandah, 
about 50 feet distant, two of them that were lying
