In water the temperature rose 46 deg. F. and 62 deg. F. in 
10 minutes, and in air 96 deg. F. in 12 minutes. In water the 
temperature fell 16 deg. F and 11 deg. F. in 10 minutes and 
in air 26 deg. F. in 15 minutes. 
Even though conditions were imperfect, the tables show 
that the eggs are not subjected to sudden changes of tem- 
perature. Nests which were entirely immersed in water for 
134 hours, showed interiors perfectly dry. At the end of two 
hours, however, the porous rind became somewhat moist, but 
the water had not reached the core. 
This porous rind, in practically all nests, varied from two 
to seven millimeters in width, with an average of 5.6 mm. 
Fifteen nests, cut transversely in half, showed the follow- 
ing measurements. 
Width of Core. Width of rind on each side.
