It should be borne in mind that the recommendations made above 
are suitable only for fresh eggs in which it is desired to examine the yolk 
and white separately. In old market eggs, or preserved eggs in which 
the yolk is weakened, and in decomposed eggs in which the yolk and 
white have become mixed, different methods would be required; and 
here, as in the bacteriological examination of other egg products, the 
technique must be evolved ih accordance with the particular aim of the 
investigation.

shapes may be used for the immersion of the eggs in the disinfecting solution, in the 
alcohol and during ignition. 
Methods for the detection of anaerobic microorganisms probably do not present 
unusual difficulties. The method of Hesse, involving the use of a layer of sterile 
olive or paraffin oil over the surface of the mixture is probably the best. In this 
case samples may be withdrawn by means of a sterile pipette.
