favorable as those secured in feeding the two lots of uncooked jtender- 

 loin, as shown in Table 6. Pens 33 and 34 were fed rations containing 

 15 and 25 per cent of cooked ham. One bird, No. 58, in pen 33 was 

 removed on the thirty-fifth day on account of an injury, but it had 

 gained 8.8 per cent in weight at the time. The other birds were in 

 fine condition at the end of the test. The average gain in weight 

 was 1.5 per cent. The birds in pen 34 were in fine condition at the 

 close of the test and the average gain in weight was 5.6 per cent. By 

 referring to Table 6, it will be noted that the average gains in weight 

 of pens 23 and 24, respectively, getting raw ham, were somewhat 

 higher than those of pens 33 and 34 which were fed corresponding 

 percentages of cooked ham. This indicates a slightly lower anti- 

 neuritic value for the cooked ham.

DISCUSSION OF RESULTS. 



Since the identity of the antineuritic vitamin and the B-growth 

 vitamin, though highly probable, is not yet proved, information on 

 the subject is of interest. In the experiments which are reported in 

 this paper it has been noted that, as a rule, though with a few excep- 

 tions, a marked decline in weight precedes the development of poly- 

 neuritis. Occasionally, however, a pigeon will lose over a third of 

 its initial weight without developing the disease; on the other hand, 

 if a bird maintains its weight, it is only rarely that it develops poly- 

 neuritis. These relations may be clearly seen by comparing the charts 

 and tables in Part I of this paper. These facts are simply another 

 indication of the close relationship that is known to exist between the 

 antineuritic and the B-growth vitamins. 



The wide difference which was found in the antineuritic properties 

 of the ox and sheep muscle on the one hand and the hog muscle on the
