1 In calculating the percentage of grease in the last three columns the amount of grease removed bv 4 
gasoline treatments is accepted as the total amount contained in the samples and is used as a basis, because 
the per cent of difference between the grease removed by the third and by the fourth treatment is shown to 
be negligible, the average being only 0.3. 
2 The weight of grease removed is determined by the subtraction of the conditioned weight of degreased 
wool from the condit ioncd weight of greasy wool. It is shown in the previous discussion that not all niois- 
tnre is removed by conditioning. However, variation in moisture content of conditioned wool is not suffi- 
cient to cause appreciable error. Consequently slight errors caused bv overweight due to moisture in the 
degreased samples occur at times but arc not sufficient to affect the value of the final results. 
The average results in Table 5 show that from the Rambouillet 
fleece samples the grease removed by one treatment was 15.04 per cent 
of the conditioned weight of raw wool; 17.31 by two; 18.11 by three; 
and 18.15 by four. The average results from the crossbred fleece 
samples were 12.09 per cent of grease removed by one treatment; 13.19
