D, plate; E, phosphorus paste; F, oven. The phosphorus
paste of Boettger, 1842, contained 10 phosphorus, 25 antimony sulfide,
12.5 manganese dioxide, 15 gelatin. According to Figuier (page 579), R.
Wagner substituted lead dioxide for the manganese dioxide. (From
FIGUIER, volume 3, 1874, page 576.)]
