Fig. 1 Reaction of Slurry Fallout Particle on Reagent Film. The white circular area is halide reaction representing 2.9 x 10 1 g NaCl. The central elliptical area is slurry artifact of insoluble solids representing 7.2 x 10°? cc, Particle density is 1.19 g/cc. The annular rings in the chloride reaction area are thought to be a Liesegang phenomenon. =3- LOL EEE ee
