3.45 respectively in the after feeding condition. The condition 

 of feeding also showed an increase of the mean, 9.97, and the 

 standard deviation, 3.79, showing a marked reaction to the 

 stimulus of feeding, more so than was shown in Three H and 

 very nearly as great as in Seven H. Consequently, the nervous 

 activity of Two H increased during feeding. 



Finally, studying the composite of Five H, (Fig. 5), we see 

 that a very nervous animal is indicated, which is readily shown 

 by the conformation of the three polygons. Many variations 

 exist and the polygons appear irregular and straggling. Here 

 again the feeding stimulus shows its effect in increasing the 

 nervous activity of the animal. The mean and standard 

 deviation, (8.22 and 4.15), in the before feeding condition, 

 increased to 11.97 and 5.16 respectively, in the feeding con- 

 dition. Comparing the before and after feeding conditions, the 

 mean S.22 and standard deviation 4.15 in the before feeding 

 condition decreased to 7.92 and 3.09 in the after feeding con- 

 dition, instead of increasing as was shown in the former subjects. 

 This may seem contradictory, but may be explained by the 

 fact that the pneumographic tracings of Five H in the after 

 feeding condition were taken too far away from the regular 

 feeding time. Consequently, the mean decreased instead of 

 increased. Had the after feeding condition been recorded 

 nearer the feeding condition, the mean probably would have 

 increased, and so established a like condition as in the first 

 three animals. Taking the after feeding record farther away 

 from the regular feeding time, up to a certain point, the nervous 

 activity decreased, and with it the mean, as has been before 

 explained. Because of the time element then the after feeding 

 condition in this case would tend to indicate less nervous 

 activity than in the before feeding condition. 



In this connection an interesting fact might be brought 

 out regarding all the subjects studied. Looking at all the 

 polygons of the feeding condition, it will be noted they extend 

 to the right of the others and are wider and flatter. Then 

 in the after feeding condition the polygons move toward the 

 left and become higher and narrower. And in the before 

 feeding condition the polygons are a little to the right of the 

 after feeding condition and slightly wider and flatter than in 

 the after feeding condition, with the exception of Two H, 

 where the before feeding tracings were taken farther from
