‘DISCUSSION OF RESULTS 
The deterioration of the summer-packed material, as measured by 
the loss of available chlorine, was regular for the first nine months, 
(Table 3 and figs. 2 and 3.) After this time samples from packers 
C and D deteriorated more rapidly than those from packers A, B, 
and KE. The material put up by packers C and D came from different 
manufacturers, who SEs made material for packers A and E. The 
excessive deterioration is therefore ascribed to the type of container | 
in which the samples were packed rather than to the method of manu- 
facture. At the end of the experiment the samples from packers | 
C and D contained more water than those from packers A, B, and E

indicating that the containers were not tight. The subsamples from 
packers C and D kept in glass bottles deteriorated at about the same 
rate as those from packers A, B, and EK. ‘Thus it is evident that the } 
difference in the behavior of the various series of samples was due to | 
the containers in which they were packed. 
During the experiment the paraffined fiber containers of all sizes | 
used by packer C and those of the 5-pound size used by packer D- 
became brittle after 5 or 6 months. The 12-ounce containers of 
packer C became noticeably brittle after storage for 3 months. 
The other containers of packers C and D showed evidence of deteriora-_ 
tion after standing for 8 to 9 months. i
