LIZARDS. 89 
and active, they do not seem, when at liberty, as a rule, to range 
far from their holes or natural homes. I have known escaped 
foreign Lizards of this genus to keep for weeks in or near the 
same spot, appearing there with great regularity every bright 
day, to bask in the sun, and to watch for prey, until, very often, 
they were finally re-captured. Indeed, if a Lizard’s Vivarium be 
placed with the door open in a retired position on some lawn or in 
a kitchen garden in all probability the inmates will, provided 
that they are quite tame, come out of the case in the day-time 
and roam about in its very near neighbourhood, and return 
to it at night, or whenever the weather ceases to be fine and 
sunny. 
The Eyed Lizard is oviparous, and occasionally deposits its 
eggs when in confinement. If the eggs are laid within a reason- 
able period after the animal’s capture, it is quite worth while to 
attempt to hatch them. 
These eggs, as well as those of other Lizards, can be artificially 
incubated and the young reared without much difficulty. They 
may be hatched in an ordinary chicken-incubator or in a small 
tin canister placed in a sufficiently warm situation. The length 
of time expended in the hatching depends upon the temperature 
with which the eggs are surrounded. I have found about 96deg. 
Fahrenheit a suitable heat for the incubation of the eggs of 
Reptiles. It is important to see that the atmosphere of whatever 
incubator used is not so dry as to shrivel the eggs, nor so moist 
as to encourage the growth of fungus. If an ordinary tin canister 
be employed for the hatching of Lizards’ eggs, the bottom of it 
should be covered rather thickly with damp moss, above which 
the eggs ought to be packed interspersed with more moss. <A few 
small holes for ventilation should be made in the lid of the tin. 
A good position for this rough-and-ready canister-incubator is 
to place it upon the top of the little boiler which is used 
to heat such a Vivarium as that illustrated at Fig. 6. Of 
course the temperature ought to be watched and tested from 
time to time. 
The young Lizards will be ready to feed almost directly they 
have left the shell, and they can be reared without difficulty if 
the directions, which will be given in another place, are followed.
