favorable as those secured in feeding the two lots of uncooked tender- 
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 percent. 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
