THE MONTHLY MICROSCOPICAL JOURNAL. JUNE 1, 1874. I.—On certain Beaded Silica Films Artijicially Formed. By Henry J. Slack, , Sec. (Bead be/ore tlie Royal Microscopical Society, May 6, 1874.) Plate LXIII., and upper part of LXIV. On a former occasion the writer called the attention of the Societyto the large number and variety of beaded patterns that could beobtained by making the artificial diatoms of Max Schultze. Informing these objects silicic fluoride gas is allowed to come intocontact in its nascent state, with cotton filaments moistened withwater. The result is a deposition of silica in the shape of irre-gular vesicles, the waUs of which exhibit beaded structures indefinite patterns; the beads in different, and in similar patterns,varying greatly in size; and many of the patterns being composedof two or more sized beads, usually symmetrically arranged. When the silica in this gaseous state comes into contact withwater, in a mass instead of being distributed in fin
