DETERMINING GREASE AND DIRT IX Wool.. 
13 
by two; 14.78 by three; and 15.10 by four. This indicates that after 
three treatments of gasoline the remaining grease is not sufficient to 
cause any appreciable error, there being only 0.04 per cent removed 
by the fourth treatment from the Rambouillel samples and 0.32 
per cent from the crossbred. 
The results of three other runs of 20 samples each of Rambouillets 
and crossbreds (based on the results of Table 5, which show that three 
is the least number of treatments which can be used) show in Table 6 
the amount of grease removed by each extraction above the third 
until the samples are free from grease.

each succeeding treatment.
