lodgings, placing them under a circular glass dome, of 10 inches diameter, 
with a few leafy twigs of koromiko (Veronica salicifolia), and giving them 
water in an oblong flint-glass salt-cellar, which, from its form and thick- 
ness, they could not upset. I knew they must be hungry, and I tried them 
with several things in the way of food, as bits of meat, both raw and cooked, 
of various fruits, of bread, of succulent roots and vegetables, and with small 
larve (caterpillars), but nothing would they touch. At last, as the warm 
weather came on, I tried them with a few flies, which were killed, or made 
motionless, in catching, these, also, they would not touch, or even look at. 
At length I put some living flies into their crystal palace, and these they 
soon caught and ate—that is the three adult lizards. For a long time I 
sought in vain for very small tiny flies for the young ones, and when I did 
succeed in getting a few, it was some time before the baby lizards 
managed to catch and swallow any (although the little things pursued them 
with longing eyes!) as the fly, when caught, in struggling, would often 
escape out of their tiny mouths, which was the more easily effected through 
the lizards not having any teeth to hold by, and the powers of the young 
ones were but feeble through their long fasting. One day I happened to 
give them three or four of the large red-brown viviparous flesh-fly (Musca 
lemica), thinking the large lizards, at least, would now have a good meal, 
and when I was not a little surprised to see them scuttle about in all direc- 
tions, wholly turning away from these flies, and apparently endeavouring to 
hide themselves (or their heads) among the koromiko leaves. For some 
time I did not understand this new movement, and I subsequently noticed, 
that while some of these red-brown flesh-flies were eaten (being gone), 
others were left dead on the floor of their cage. 
Early in November I was sorry to observe that the young ones, although 
all four had grown rapidly in length, were daily becoming more weak, 
especially the two entirely green ones; this, of course, was owing to their 
not eating. On the 8rd of November one of the young green ones died. 
At this time, too, the head of one of the adult lizards (as I believe, the 
female one) swelled much, changed to a livid colour, and grew to an un- 
shapely size, with a bloody discharge distilling from its ears. I thought, 
that something being the matter with its head, the other lizards in their 
scrambling about over each other (which they commonly do) had fixed their 
sharp claws in its ears, being now tender, and so caused them to bleed, &c. 
The sick lizard, however, was very patient under it; and as its disorder 
increased, the skin of its head became more and more stretched with the 
swelling, and great and irregular throbbings or undulations were very 
apparent. (Here I should mention, that the regular pulsation in their 
throats is always prominently seen), And so, as this diseased lizard became
