No. 411.] INCUBATION OF ALLIGATOR EGGS. 195 
have been contained in so small an egg is quite astonishing. 
These three artificially hatched alligators are now living, in 
apparent good health, in a glass-covered box in the laboratory. 
They are fed, about once a week, on small bits of raw meat 
which are thrown into the shallow pan of water in their box. 
It is probable that had the first lot of eggs been treated as was 
the second lot, the desired stages of development might have 
been obtained.
