Rh explained in this way, and I look upon it as an inherited tendency. But may not the habit have originated in the hunger of the chick, and have been worked in, sexually, at a later age, when the reproductive system had become active? Strong emotion, one may suppose, would require an outward manifestation in the shape of movements of some sort, and it would be such as were already known, that, by first coming to hand, would be likely to be first employed. If we had been accustomed to do one kind of work for which we had a suitable implement, and it became suddenly necessary to do some other for which we had none, it would be natural for us to catch up the one we had and make a shift with that. If a swim-bladder can be worked in as a lung, or a pair of legs as part of a mouth, then why not a hunger-signal as a love-signal? Be this as it may, it is certainly strange to see little fluffy chicks on the nest going through the same sort of pantomime as their parents do when in love. But why do I call them little? I have never seen such big baby things, and their size makes them look all the weirder. So great, indeed, is the chick's fluffiness that though the wings are tiny and the tail invisible, it looks almost, if not quite, as big as the graceful and delicately shaped parent bird sitting beside it.

The lethargy of these young fulmars is very noticeable. They do occasionally rise a little on their feet and shuffle about in the place where they sit, so that in this way they may, in time, turn quite round.
