40 WESLEY MILLS ON. 



feet they can follow the movements of an oliject the size of a table napkin. Both the eyes 

 and head are moved. 



On striking a single blow on the bottom of a watering can they all rushed olf to the dis- 

 tant part of the pen with all the expressions of fear. 



They are now well supplied with teeth in both jaws, but in regard to this also, there are 

 individual differences. 



They iday much more. 



Being rather chilly to-day they huddle together. 



Same day at 7 p.m. When all are playing, a slight but well defined sound causes them 

 all to stop at once. 



When the hand is put down in front of them after they recover, one comes up wagging 

 the tail. 



The eyes are now very widely open, the expression changed, and the}' can follow the 

 movements of a table napkin at a distance of six to seven feet ; but winking by the old test 

 is not appreciably more pronounced. 



One of the puppies when placed on the floor of the kennel covered with sawdust, plays 

 about, cries and is evidently very uneasy, if not confused. When put on the top of the box 

 on which they are usually fed, it sniffed and looked towards the white plate from which 

 they drink their milk. When held in the arms it soon manifests uneasiness — when placed 

 near the edge of the box it grew very uneasy, but does not jump off. Almost at once 

 when placed back in the pen it became quiet and soon began to play. By its movements 

 they indicate clearly that the direction of sound is perceived. 



21th day. — The puppies follow a small object (3x1 inches) dangled before them at 15 

 inches. 



One is observed playing with a straw three or four inches from it. In this act there is 

 the use of the mouth and the forelimb with all that this implies. 



There is clear evidence that sounds made at the outer door of the kennel and in the 

 adjacent yard are heard. 



A basket in which meat had been kept and giving off a strong odour when brought 

 near the pen is plainly smelled. The dam is brought within about three feet of the puppies 

 but unseen by them. First one and then another begin to sniff and soon to cry. 



The playing shows advance ; better use is made of the hind limbs, which develoj^ func- 

 tionally much more slowly than the forelegs. The head and neck movements are also better 

 in all respects. 



Now and even some days since increase in the quantity and quality of the coat, with 

 changes in the shape of tlie head are evident ; and in both physical and psychic characteristics 

 individuality is to be noted. 



To-day play seemed in one case to change into a little quarrel for a few seconds. 



One is observed to utter an abortive hark in its sleep. 



28^/( day. — INoises above the kennel in my pigeon loft have greater effect on the puppies 

 than on the mature dogs in the adjoining kennel. 



They can now follow with the eyes the small objects used in all these experiments at a 

 distance of four or five feet ; while a napkin, etc., can be followed anywhere within their 

 kennel conqiartment. 



Various objects as a plate, glass, a folded napkin and a Spratt's dog biscuit, are pre- 

 sented, but they mouth all about equally, so that distinct selective choice is not shown.
