X-ray electron probe scan of the distribution of strontium and sulfur in an insect (area 320 micron square). but occasionally they have had an arrangement indicating that min- eralization proceeded by the formation of a few large, parallel oriented crystals (Fig. 6). The size of the individual crystals can be estimated from the size of the spots they produce; they commonly range between 10"- and 10"^ cm. in diameter, the celestite fossils being composed of crystals larger than those of quartz. In a few cases the mean crystallite size has been so small that the powder patterns have been completely devoid of spots. For many of the celestite insects, the crystallites have been so big and numerous that identification could.
