*It is not certain that the principle of unique royalty, or maternity, is strictly observed among the Meliponitae. Blanchard remarks very justly, that as they possess no sting and are consequently less readily able than the mothers of our own bees to kill each other, several queens will probably live together in the same hive. But certainty on this point has hitherto been unattainable owing to the great resemblance that exists between queens and workers, as also to the impossibility of rearing the Meliponitae in our climate. It is in our domestic bees, therefore, that the idea, of whose movements we have given a cursory and incomplete picture, attains its most perfect form. Are these movements definitely, and for all time, arrested in each one of these species, and does the connecting-line exist in our imagination alone? Let us not be too eager to establish a system in this ill-explored region. Let our conclusions be only provisional, and preferentially such as convey the utmost hope, for, were a choice forced upon us, occasional gleams would appear to declare that the inferences we are most desirous to draw will prove to be truest. Besides, let us not forget that our ignorance still is profound. We are only learning to open our eyes. A thousand experiments that could be made have as yet not even been tried. If the Prosopes, for instance, were imprisoned, and forced to cohabit with their kind, would they, in course of time, overstep the iron barrier of total solitude, and be satisfied to live the common life of the Dasypodae, or to put forth the fraternal effort of the Panurgi? And if we imposed abnormal conditions upon the Panurgi, would these, in their turn, progress from a general corridor to general cells? If the mothers of the humble-bees were compelled to hibernate together, would they arrive at a mutual understanding, a mutual division of labour? Have combs of foundation-wax been offered to the Meliponitae? Would they accept them, would they make use of them, would they conform their habits to this unwonted architecture? Questions, these, that we put to Very tiny creatures; and yet they contain the great word of our greatest secrets. We cannot answer them, for our experience dates but from yesterday. Starting with Reaumur, about a hundred and fifty years have elapsed since the habits of wild bees first received attention. Reaumur was acquainted with only a few of them; we have since then observed a few more; but hundreds, thousands perhaps, have hitherto been noticed only by hasty and ignorant travellers. The habits of those that are known to us have undergone no change since the author of the "Memoirs" published his valuable work; and the humble-bees, all powdered with gold, and vibrant as the sun's delectable murmur, that in the year 1730 gorged themselves with honey in the gardens of Charenton, were absolutely identical with those that to-morrow, when
