Hence we learn, that a moderately sized egg loses, at an ave- 
rage, about .75 gr. in twenty-four hours, and this uniformly 
during a very long period. The loss appears to be somewhat 
greater in summer than in winter, owing, doubtless, to the dif- 
ference in temperature, which, in the above instance, varied 
from 40° to 70°. The whole of the contents of this egg were 
found collected at the smaller extremity in a solid state, but, on 
being put into water, they absorbed a large quantity of it, and 
assumed an appearance not much unlike that of a recent egg, 
the smell being also perfectly fresh. 
The relative weights of the shell, albumen, and yolk of dif- 
ferent eggs are very different. With the view of investigating 
this subject, and of obtaining an average, the following experi- 
ments were made. The eggs were boiled hard in distilled wa- 
ter, and the different parts weighed immediately in their moist' 
state:
