1 In calculating the percentage of grease in the last three columns the amount of grease removed by 4 

 gasoUne treatments is accepted as the total amount contained in the samples and is used as a basis, because- 

 the per cent of difierenee between the grease removed by the third and by the fourth treatment is shown to 

 be neghgible, the average being only 0.3. 



2 The weight of grease removed is determined by the siabtraction of the conditioned weight of degreased 

 wool from the conditioned weight of greasy wool. It is shown in the previous discussion that not all mois- 

 ture is removed by conditioning. However, variation in moi.¥ture content of conditioned wool is not suffi- 

 cient to cause appreciable error. Consequently sUght errors caused by overweight due to moisture in the- 

 degreased samples occur at times but are not sufficient to affect the value of the final results. 



The average results in Table 5 show that from the Eambouillet 

 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
