separately, [ have divided the observations into four groups, 
and taken the average value of the corresponding data for all 
the vessels included in a group, and the results are given i 
table V. No. 1 indicating a pressure much less than any other 
vessel is allowed to stand by itself and forms the first line of 
table V. Nos. 2-6 showing pressures between 28°0 and 28° 
inches form the second group, and the average of the observa- 
tions for these five vessels is given in the second line of table 
. Nos. 7-11 showing pressures between 28°5 and 29-0 inches 
form the third group and the averages are given in the third
