But some late curious discoveries relating to bees having escaped the compiler of that article, we shall here supply the omission; and it is hoped that the importance of these discoveries, considered either in a philosophical or an economical view, will be a sufficient excuse for exhibiting them at so great length.

"Discoveries on the sex of Bees, explaining the manner in which their species is propagated; with an account of the utility that may be derived from these discoveries by the actual application of them to practice." The most skilful naturalists have been strangely misled in their opinion, that the bees, as well as the other tribes of animals, are perpetuated by copulation; though they acknowledge that they have never been able to detect them in the act. This part of phytics has been the principal object of my researches for several years past, having been indefatigably engaged in it by the pleasure I took in so curious an inquiry. The results of various experiments, made all in glass-hives, which carry with them an entire evidence, afford sufficient reasons to assert, that bees belong to that class of animals among which, although they have sexes, a true copulation cannot be proved; and that their eggs, like the spawn of fishes, most probably owe their fecundation to an impregnation from the males, as will appear in the sequel of this narrative.

"In order to be the better understood in the relation of my own experiments on the fecundation of bees, I here premise the outlines of the opinions generally adopted by naturalists on that head. They affirm, that the queen is the only female in the hive, and the mother of the next generation; that the drones are the males by which she is fecundated; and that the working bees, or bees that collect wax on the flowers, that knead it and form from it the combs and cells which they afterwards fill with honey, are of neither sex.

"But of late Mr Schirach, a German naturalist, has given us a very different view of the classes that constitute the republic of bees, in an ingenious publication in his own language, under the title of The Natural History of the Queen of the Bees; from which I beg leave to relate the author's doctrine with regard to the working-bees only, the quality and functions of the drones being points which do not appear to be yet settled by Mr Schirach himself. He affirms, that all the common bees are females in disguise; in which the organs that distinguish the sex, and particularly the ovaria, are obliterated, or at least, through their excessive minuteness, have not yet been observed; that every one of those bees in the earlier period of its existence is capable of becoming a queen-bee, if the whole community should think proper to nurse it in a particular manner, and raise it to that rank. In short, that the queen-bee lays only two kinds of eggs; viz., those that are to produce the drones, and those from which the working-bees are to proceed.

"The trials made by Mr Schirach seem to evince the truth of his conclusions in the most satisfactory manner, singular as they appear to be at first sight; and indeed, in my own judgement, from the constant happy result of my numerous experiments, which I began near two years before Mr Schirach's publication, and repeated every season since, I am enabled to pronounce on their reality. Chance befriended me in that discovery, whilst I was most anxiously endeavouring to ascertain the use of drones. It was in the spring of the year 1770, that I for the first time discovered what Maraldi had only conjectured, I mean the impregnation of the eggs by the males, and that I was made acquainted with the difference of size in the drones or males observed by Maraldi in his Observations upon Bees. We have of late found great quantities of drones much smaller than those we had formerly observed, and which of Sciences do not exceed in size the common bees; so that it would not have been easy to distinguish them in that hive from the common bees, had not the quantity of them been very considerable. It might certainly have happened that in those hives, where we have not been able to discover large drones, there were a great number of those little ones, which may have been intermixed among common bees when we were yet ignorant that any such small drones were existing."

Reaumur himself says, "We have likewise found drones that were no bigger than the common bees." They have notwithstanding escaped the observation of Mr Schirach, and of his friend Mr Hattorf member of an academy in Lusatia, who, in a memoir he presented in the year 1769, annihilates entirely the use of drones. drones in a hive; and advances this singular opinion, that the queen-bee of a hive lays eggs which produce young ones, without having any communication with the drones. For what purpose should wise nature then have furnished the drones with that large quantity of seminal liquor? To what use so large an apparatus of fecundating organs, so well described by Reaumur and Maraldi?

"But I beg leave to remark, that those gentlemen seem to have drawn too hasty conclusions from their experiments, in rejecting the drones as bearing no share in the propagation of those insects. Their observations, that hives are peopled at a time of the year when there are no drones in being, are no ways conclusive; as it is evident, that they had seen none but drones of a large size, their silence on the difference in the size of them justifying my remark. But to resume the narrative of my experiments: I had watched my glass-hives with indefatigable attention from the moment the bees, among which I had taken care to leave a number of drones, were put into them, to the time of the queen laying her eggs, which generally happens the fourth or fifth day. I observed the first or second day (always before the third) from the time the eggs are placed in the cells, that a great number of bees, fastening themselves to one another, hung down in the form of a curtain from the top to the bottom of the hive, in a similar manner they had done before at the time the queen deposited her eggs; an operation which (if we may conjecture at the instincts of insects) seems contrived to hide what is transacting: be that as it will, it answered the purpose of informing me that something was going forward. In fact, I presently after perceived several bees, the size of which through this thick veil (if I may so express myself) I could not rightly distinguish, inserting the posterior part of their bodies each into a cell, and sinking into it, where they continued but a little while. After they had retired, I saw plainly with the naked eye a small quantity of a whitish liquor left in the angle of the basis of each cell, containing an egg: it was less liquid than honey, and had no sweet taste at all. Within a day after, I found this liquor absorbed into the embryo; which on the fourth day is converted into a small worm, to which the working bees bring a little honey for nourishment during the first eight or ten days after its birth. After that time they cease to feed them; for they shut up the cells, where these embryos continue inclosed for ten days more, during which time they undergo various changes too tedious here to describe.

"To evince the reality of this observation, and to prove that the eggs are fecundated by the males, and that their presence is necessary at the time of breeding, I proceeded to the next experiments. They consisted in leaving in a hive the queen with only the common bees, without any drones, to see whether the eggs she laid would be prolific. I accordingly took a swarm, shook all the bees into a tub of water, and left them in it till they were quite senseless, which gave me an opportunity to distinguish the drones without any danger of being stung. After I had recovered the working-bees and their queen from the state they were in, by spreading them on brown paper in the sun, I replaced them in a glass-hive, where they soon began to work as usual: the queen laid eggs, which I little suspected to be impregnated, as I thought I had separated all the drones or males, and therefore omitted watching the bees; but at the end of 20 days (the usual time of their hatching) I found to my surprize some of the eggs hatched into bees, others withered away, and several of them covered with honey. I immediately inferred that some of the males, having escaped my notice, had impregnated only part of the eggs; but, in order to convince myself of the truth of my supposition, I thought it necessary to take away all the brood-comb that was in the hive, in order to oblige the bees to provide a fresh quantity, being fully determined to watch narrowly their motions after new eggs should be deposited in the cells. This was done accordingly, and at last the mystery was unravelled. On the second day after the eggs were placed in the cells, I perceived the same operation which I have related in a former experiment; I mean, the bees hung down in the form of a curtain, while others thrust the posterior part of their body into the cells: I then introduced my hand into the hive, broke off a piece of the comb containing two of those insects, and kept them for examination. I found in neither of them any thing (a circumstance peculiar to drones only); and upon dissection, by the help of a Dollond's microscope, discovered in them the four cylindrical bodies, which contain the glutinous liquor of a whitish colour, observed by Maraldi in the large drones.

"Having till then never observed any difference in the size of drones, I immediately perused the Memoirs on Bees published by Messrs Maraldi and Reaumur, and found that they had remarked it frequently. The reason of that difference must, I doubt, be placed amongst other arcana of nature. I found myself therefore under a necessity, in my next experiments, to be more particular in destroying the males, even those which might be suspected to be such.

"I once more immersed all the same bees in water; and, when they appeared to be in a senseless state, I gently pressed every one of them between my fingers, in order to distinguish those armed with stings from those that had none, which last I might suspect to be males. Of these I found 57, exactly of the size of common bees, yielding a little whitish liquor on being pressed between the fingers. I killed every one, and replaced the swarm in a glass-hive, where they immediately applied again to the work of making cells; and on the fourth or fifth day, very early in the morning, I had the pleasure to see the queen-bee depositing her eggs in those cells, which she did by placing the posterior part of her body in each of them. I continued on the watch most part of the ensuing days, but could discover nothing of what I had seen before.

"The eggs, after the fourth day, instead of changing in the manner of caterpillars, were found in the same state they were in the first day, except that some of them were covered with honey. But a very singular event happened the next day about noon: all the bees left their own hive, and were seen attempting to get into a neighbouring common hive, on the stock of which I found their queen dead, having, no doubt, been slain in the engagement. The manner in which I account for this event is as follows: the great desire of perpetuating their species, which is most observable in these insects, and to which end the concurrence of the males seems so absolutely necessary, made them desert their own habitation where no males were left, in order to fix their residence in a new one, in which, there being a good stock of males, they might the better accomplish their purpose. If this does not yet establish the reader's faith of the necessity of the males bearing a share in the fecundation of the ova, the next experiment cannot, I presume, fail to convince him.

"I took the brood-comb which, as I observed before, had not been impregnated; I divided it into two parts; one I placed under a glass-bell No. 1, with honey-comb for the bees' food; I took care to leave a queen, but no drones, among the common bees I confined in it. The other piece of brood-comb I placed under another glass-bell No. 2, with a few drones, a queen, and a number of common bees proportioned to the size of the glass; the rest I disposed of as before. The result was, that in the glass No. 1, no impregnation happened; the eggs remained in the same state they were in when put into the glass; and, upon giving the bees their liberty on the seventh day, they all flew away, as was found to be the case in the former experiment: whereas in the glass No. 2, I saw, the very day after the bees had been put under it, the impregnation of the eggs by the drones in every cell containing eggs; the bees did not leave their hive on receiving their liberty; and, in the course of 20 days, every egg underwent all the above-mentioned necessary changes, and formed a pretty numerous young colony, in which I was not a little startled to find two queens.

"Fully satisfied concerning the impregnation of the eggs by the males, I desisted for the present from any further experiments on that head, being exceedingly anxious to endeavour to account for the presence of this new queen.

"I conjectured that either two queens, instead of one, must have been left among the bees I had placed under that glass; or else that the bees could, by some particular means of their own, transform a common subject into a queen. In order to put this to the test, I repeated the experiment with some variation. I got four glass-hives blown flat, which I thought preferable to the bell-shaped ones I had used before, as I could with those better examine what was going forward. I took a large brood-comb from an old hive, and, after having divided it into several pieces, I put some of them containing eggs, worms, and nymphs, with food, viz.: honey, &c., under each of the glasses; and confined within each a sufficient number of common bees, among which I left some drones, but took care that there should be no queen.

"The bees finding themselves without a queen, made a strange buzzing noise, which lasted near two days; at the end of which they settled and betook themselves to work; on the fourth day I perceived in each hive the beginning of a royal cell, a certain indication that one of the inclosed worms would soon be converted into a queen. The construction of the royal cell being nearly accomplished, I ventured to leave an opening for the bees to get out; and found that they returned as regularly as they do in common hives, and showed no inclination to desert their habitation. But, to be brief, at the end of twenty days, I observed four young queens among the new progeny.
