Determination of Ether Extract prom the Solids Dried With and 



Without Sand. 



The analyst who proposed the use of sand in the determination of 

 solids noted that sand had no effect on the amount of ether extract 

 obtained from whole egg or yolk, and did not seem to accelerate the 

 extraction. The figures which he obtained are given in Table 29.

Effect upon Ether Extract Determination of the Amount of Sample Used 

 for Total Solids Determination. 



The difference is so small as to show that either amount may be 

 used, with a slight preference for the larger amount because of greater 

 uniformity (Table 30).
