In studying the data contained in Table XVIII, we notice the 
following points of interest: 
(1) During the first three months, the loss of solids was very 
marked, though varying in degree in different experiments. The 
decrease of solids was move gradual after the third month. 
(2) The loss was not uniform in the different experiments 
when the apple juice used varied in composition as in experi- 
ments 1 to 10; and even when the same apple juice was used, 
as in experiments 11 to 16, 17 to 21, 29 to 36, the loss of solids 
varied. 
(3) In several cases, the amount of solids was below 2 per 
ct. when the acetic acid was above 4.5 per ct., as in experi- 
ments 4,7, 8, 16, 18, 19, 20,°227 Bi a2) ra oe 
(4) In old vinegar standing in a cask with the bung-hole 
open, there is evaporation of water and this may be considerable,
