crown to this apparently drone root—the change whichproceeds is astonishing and the prosthesis is perfect. The method is simple and effective. Prepare the badlydecayed root as one in ordinary practice, ream out all thebroken-down tissue and depend on sound structure, fit thecrown, be it Logan, Davis, Brewster or Justi, in the usualmanner; just before setting same apply a bit of wax to themetallic post and insert in the cosmolined canal. At first intro-duction you may have an excess of wax; remove, and overalcohol flame soften and trim where indicated, then reinsertand after getting a good, accurate adaptation, the initial step THE DENTAL SUMMARY 505 is complete (Fig. i). Then lake the crown with its wax-encased post and invest entirely in the ring of your castingapparatus and after freeing the wax from investment andbeing assured of the perfect dryness of the case proceed toliquidate the gold and by means of air, steam, or better still,suction, cast the case.

cells. In the drawing given, youwill see cells in different stages of growth. At A, is a cell just being converted into aqueen-cell; at B, one where the thin wallsare extended so as to form a queen-cell prop-er, almost ready to seal up. This occurs atjust about 9 days from the time the egg Avaslaid. In 7 days more, 16 days in all fromthe time the egg was laid, the queen willhatch out, a perfect insect. C is a cell justvacated. Now bear in mind exactly what 1 QUEERS. 227 QUEENS. say, or you will get confused. If, instead ofeggs, larvae 3 days old are given the bees, theywill rear a queen, and, in this case, she willhatch in only ten days after the larvae weregiven them. These ten-day queens may bejust as good as any;*^ but to be on the safeside. I would prefer giving them larvte oneor two days younger, that they might havethe benefit of this excess of food and largercell, during the whole of their larval period.The six-day larvje are quite large fellows, asyou will see by the cut at F.

QUEEX-CELLS. There are some queer things about queen-cells, as you will notice. After the cell issealed, they go and put a great excess ofwax on it, give it a long tapering point, andcorrugate the sides something like a thim-ble, as shown at C This corrugation, orroughness, when closely examined, will beseen to be honey-comb on a very small scale.Now right here is a point that you will notfail to observe : Bees, like other folks, some-times make mistakes ; for they do not seemto know any better than to use a drone-lar-va for rearing a queen, if such happens tobe present. Therefore, when selecting eggsfor this purpose, be sure you do not givethem any contained in drone comb. Theywill go right on, and dose the poor dronewith the royal jelly, but the poor fellow usu-ally dies before it is time to hutch out, andthen the bees and their owner wait in vainfor the cell to hatch. It has been reportedof late, that the inmate of sucli a cell some-times hatches, but he is only a drone, eventhen,
