and fixate the pan. Tail wagging and other postural move- 

 ments are correlated with the head movement. After the 

 food is eaten they remain active and alert. 



The behavior charts (text-figs. 94 and 95) of German shep- 

 herd 438 9 and a Saluki-bassethound F 2 1382 9 are typical 

 of this group. As the chart for 438 9 shows, the magnitude 

 of the reaction at the beginning of the experiment is no 

 greater than that of animal 83 9 (text-fig. 89). As a rule 

 there was a short delay of the conditioned reaction, as shown

in text-figures 91 (fig. 3) and 92 (fig. 2). The response was 

 intense, and did not dwindle and disappear but remained 

 at its maximum value until an undue restlessness appeared 

 in the animal. Since there is a continuation of the conditioned 

 salivary reaction, the average of the response is larger than 

 that of the animals of group A. Thus these animals retained 

 a high level of activity. The short cuts made by the dogs 

 of group A do not appear. The end product is also quite 

 different in that the animals of group B do not settle down 

 to a definite mode of performance. Spontaneous undirected
