Animal heat during incubation is not noticeableuntil about the tenth day, though a fresh, stronglyfertilized egg, having been subjected to a tempera-ture of 1030 for thirty-six hours, and then brokenin a saucer, will reveal a live, pulsating heart, thebeats of which may be counted, and it will makeabout sixty before it stops or dies. As the animal heat increases less artificial heatis required to keep up the proper temperature inthe egg chamber. On this account it is generallynecessary to occasionally adjust the regulator alittle the last week of incubation ; but the lampflame or flames should be gradually (a little at atime) lowered if it appears
