TABLE II 



In Table II, column 3, "M" signifies maie, "F" female. In column 4 "C" signifies 

 control animal, "T" thyroid-fed rat. The rat numbers given in Table II are those actually 

 used. The rats were taken in the same order in the compilation of Table I. 



The lymph-glands selected for comparison were all those macroscopically visible lying in 

 the anterior triangles of the neck along the internal jugular veins, and above the level of the 

 thyroid cartilage. The right anterior tibialis muscle was taken for comparison of muscle 

 tissue. 



Consideration of Results 



The litter used in experiment 6 was weak and undersized and 

 could not be considered normal; it was not surprising, therefore, 

 that the results in that experiment were not in agreement with those 

 from the remaining five. Experiment 6 will be considered separately.
