CHANGES IN FRESH BEEF DURING COLD STORAGE. 
59 
Table 33 shows the composition of the carcass expressed in terms 
of percentages of the fresh material. 
Table 34 shows the composition of the carcass expressed in terms 
of percentages of the moisture-free and fat-free material. 
There are appreciable losses of moisture which are somewhat 
greater, on the whole, than those observed in the case of carcass No. 3, 
stored 42 days. 
Slight changes in the ash are without significance. 
The data for total nitrogen seem to show appreciable decreases in 
this constituent. The fact that similar, though smaller, decreases 
were noted in the nitrogen content of carcasses Nos. 2 and 3, stored 
for 28 and 42 days, respectively, makes it appear that these apparent 
losses of nitrogen from the meat during storage may have some sig- 
nificance.
