round bodied, with a chest index of 90. This animal, there- 

 fore, is similar to the bassethound grandparent in bodily 

 shape, yet behaviorally it falls with the shepherd into group 

 B under each experimental situation. Therefore, the bodily 

 form and behavioral relationship found in the bassethound 

 grandparent would seem to be reversed in this case. One 

 dog of the group, 863 $ , a brother of 867 $ , is not only 

 round bodied like 867 6 but has the short legs of the basset- 

 hound. This dog looks very like a pure bassethound, as 

 shown in plate 103 (fig. 3). It is also classified in the basset- 

 hound or A group in the experiments and is considered a 

 pure A type. In this case, then, there is a body and behavior 

 correlation similar to that found in the pure bassethound 

 grandparent. 



In the F 2 s discussed thus far, 1811 $ , 1812 $ , 1152 $ , 867 S , 

 and 863 $ , there has been no wide variation in the individual 

 performances, that is, each animal gave about the same 

 type of performance in the different experimental situations. 

 Two dogs among the F 2 s, however, 1153 $ and 1528 9 , were 

 unusual in this regard. Both performed well in the condi- 

 tioned food taking situation and were classified as A-plus 

 and B-minus, respectively. Yet when they were trained in 

 the conditioned avoiding situation, they fell into a different 

 classification. For example, when the attempt was made to 

 develop the conditioned avoiding reaction in 1528 9 , the ani- 

 mal became hyper-excitable. She could not restrain the escape 

 reaction after the shock was introduced. In this case there 

 is an exaggeration of the motor systems, and in contrast 

 to the well balanced performance in the food taking situa- 

 tion, the motor situation causes hyper-excitability. This is 

 in direct contrast to the bassethound grandparent, which is 

 inactive under both conditions, and to the German shepherd 

 grandparent, which is very active but trainable in all situa- 

 tions. For this reason, 1528 9 is considered a mixed be- 

 havioral type, in that she has behavioral characteristics 

 similar to both, but with an exaggerated motor performance. 

 Animal 1153 $ followed somewhat the same pattern as 1528 $ .
