72 Dr P rout's Experiments on the Changes which tahe place 
increased in bulk and fluidity, has now apparently acquired its 
original size and consistence. The following are the results of

At this period ossification has made some progress, the yolk 
has parted with some of its phosphorus, which appears in the 
other principles of the egg, and the quantity of earthy matter 
has increased. 
Experiments on the egg at the end of the third week, or at 
the full period of incubation. 
At this period an egg has lost upon an average about 160 
grains, taking the original weight to be 1000 ; and the weight of 
the constituent principles of two eggs in their moist stated and 
without boiling, were as follows;
