In electrical weather they are never lively, even though the day be intermittingly hot and bright; and at such times they are often almost lethargic, and show great indifference as to feeding. They appear to have an extreme and instinctive objection to rain. Cloudy weather makes them dull. A passing cloud will make them discontinue eating. And the passage of a person or object suddenly between them and the sun will cause them as suddenly to draw in their heads. The dislike of clouds and their accompaniments is therefore a very marked instinct with them. If not fed, they will go and help themselves, not to grass, but to some white Clover growing with the grass in the garden; or in default of this, to some of the garden plants—by preference the fleshy-leaved ones, such as the Echiveria or Sedum—after which they will retire to some warm place, and bask in the sun. They have a special liking for the warm vine-border in front of my greenhouse; and if the day be not too hot, they will tilt themselves up edgeways against the south wall of the greenhouse, or upon the edge of some tuft of flowers; or if the sun is too warm, they will then cover their heads up with leaves or earth on the bed, leaving their backs uncovered and exposed to the heat. (In this respect they seem to remind us of the habits of the tiger in his jungle.) But they appear greatly to prefer being fed, and having their food found for them; indeed further, one, at least, much prefers to have his food held up to him, and almost put into his mouth when he opens it. They take their food with a snapping movement; masticate it little if at all; and when feeding themselves, cut or tear it with the sharp-hooked anterior portion of the upper jaw. In the hottest weather their appetites are very fine (thus they will eat several large Lettuce leaves at one time), and they bear a close relation to the warmth and clearness of the day, and the period of the year. Their favourite foods are—besides Trefoil, already mentioned, and garden flowers—Lettuces, Dandelions, French Beans, etc. They are much attracted by yellow blossoms, and greedily eat those of the Dandelion and Buttercup. One of my creatures is very fond of sliced Apple, though the other will not eat it. But the vegetable of which they are most fond is the Green Pea. Both of them will leave all other food for this, and they will consume at a meal a very considerable number of these Peas. Indeed, so fond are they of them, that they will follow a person accustomed to feed them with them about the garden, and will even try to clamber up his legs to get at them. After sleeping and basking, they will again eat, and then again sleep once or twice more during the day; but in cooler or doubtful weather, they usually eat only once a day, and sometimes not at all.
