the end of 10 days, 12 melons were removed, 6 of them being analyzed 
at once and the others allowed to stand for two days at room tempera- 
ture before analysis. The object was to represent in a measure the 
conditions to which the melons are exposed at the retail store. The 
results are shown in Table 11.

1 FR, field ripe; FS, full slip; HS, half slip; Im, immature. 
2 Refrigerator, 10 days, and at room temperature, 2 days. 
A sampling error is involved in these measurements and part of 
the change indicated is due to variation in the samples themselves. 
Six melons are not enough to represent the group. 
Averages are not given, as it is believed that greater accuracy is 
reached by considering each lot separately. Thus lot 1 shows no 
change in composition during the storage period. Lot 2 shows a 
decrease in composition during the two days in common storage, but 
none during refrigerator storage. An actual increase is apparent in 
lot 4 during refrigerator storage, but this difference is no doubt due 
to the sampling error. 
Comparing the sucrose values for the 10-day refrigerator storage 
lot with the check values, out of 24 determinations there were 15 
increases and 9 decreases. This indicates no change, as the small 
increases may have been due to loss of water by evaporation. 
A comparison of the sucrose values of the check samples with those 
of the samples stored in the refrigerator car and held for two days at 
room temperature shows 6 increases against 13 decreases. Taking 
into account the fact that any water loss by evaporation would cause
