accumulating only during three nights, seems to have lost rela- 

 tively more nitrogen than B-2, perhaps because the house was 

 much warmer than the one from which samples B came ; although 

 this seems an insufficient explanation to account for so large a 

 difference. 



Examination of Table 1, especially comparison of the samples 

 B-1 and B-2, shows that the fact that nitrogen has been lost is 

 obscured by the further fact that there has been an even 

 larger loss of water. The percentage of nitrogen in B-2 (Table 1) 

 is larger than in B-1, but only because the former is drier. Table 

 2 shows that there has been a large actual loss.
