EXAMINATION OF FROZEN EGG PRODUCTS. 79 
DETERMINATION OF ETHER EXTRACT FROM THE Sotips DrRiepD WITH AND 
WirHout 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.

sand.

Errecr veon EtaHer Extract DETERMINATION OF THE AMOUNT OF SAMPLE USED 
For Tota SoLips 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).
